Red Hat Enterprise Virtualization 3.3 Command Line Shell Guide

Table of Contents

Preface

1. Document Conventions

This manual uses several conventions to highlight certain words and phrases and draw attention to
specific pieces of information.

In PDF and paper editions, this manual uses typefaces drawn from the

Liberation Fonts

set. The

Liberation Fonts set is also used in HTML editions if the set is installed on your system. If not, alternative
but equivalent typefaces are displayed. Note: Red Hat Enterprise Linux 5 and later include the Liberation
Fonts set by default.

1.1. Typographic Conventions

Four typographic conventions are used to call attention to specific words and phrases. These
conventions, and the circumstances they apply to, are as follows.

Mono-spaced Bold

Used to highlight system input, including shell commands, file names and paths. Also used to highlight
keys and key combinations. For example:

To see the contents of the file my_next_bestselling_novel in your current working
directory, enter the cat my_next_bestselling_novel command at the shell prompt
and press Enter to execute the command.

The above includes a file name, a shell command and a key, all presented in mono-spaced bold and all
distinguishable thanks to context.

Key combinations can be distinguished from an individual key by the plus sign that connects each part of
a key combination. For example:

Press Enter to execute the command.

Press Ctrl+Alt+F2 to switch to a virtual terminal.

The first example highlights a particular key to press. The second example highlights a key combination:
a set of three keys pressed simultaneously.

If source code is discussed, class names, methods, functions, variable names and returned values
mentioned within a paragraph will be presented as above, in mono-spaced bold. For example:

File-related classes include filesystem for file systems, file for files, and dir for
directories. Each class has its own associated set of permissions.

Proportional Bold

This denotes words or phrases encountered on a system, including application names; dialog-box text;
labeled buttons; check-box and radio-button labels; menu titles and submenu titles. For example:

Choose System → Preferences → Mouse from the main menu bar to launch Mouse
Preferences. In the Buttons tab, select the Left-handed mouse check box and click
Close to switch the primary mouse button from the left to the right (making the mouse
suitable for use in the left hand).

To insert a special character into a gedit file, choose Applications → Accessories →

Red Hat Enterprise Virtualization 3.3 Command Line Shell Guide

Character Map from the main menu bar. Next, choose Search → Find… from the
Character Map menu bar, type the name of the character in the Search field and click
Next. The character you sought will be highlighted in the Character T able. Double-click
this highlighted character to place it in the Text to copy field and then click the Copy
button. Now switch back to your document and choose Edit → Paste from the gedit menu
bar.

The above text includes application names; system-wide menu names and items; application-specific
menu names; and buttons and text found within a GUI interface, all presented in proportional bold and all
distinguishable by context.

Mono-spaced Bold Italic or Proportional Bold Italic

Whether mono-spaced bold or proportional bold, the addition of italics indicates replaceable or variable
text. Italics denotes text you do not input literally or displayed text that changes depending on
circumstance. For example:

To connect to a remote machine using ssh, type ssh username@domain.name at a shell
prompt. If the remote machine is example.com and your username on that machine is
john, type ssh john@example.com.

The mount -o remount file-system command remounts the named file system. For
example, to remount the /home file system, the command is mount -o remount /home.

To see the version of a currently installed package, use the rpm -q package command. It
will return a result as follows: package-version-release.

Note the words in bold italics above: username, domain.name, file-system, package, version and
release. Each word is a placeholder, either for text you enter when issuing a command or for text
displayed by the system.

Aside from standard usage for presenting the title of a work, italics denotes the first use of a new and
important term. For example:

Publican is a DocBook publishing system.

1.2. Pull-quote Conventions

Terminal output and source code listings are set off visually from the surrounding text.

Output sent to a terminal is set in mono-spaced roman and presented thus:

books Desktop documentation drafts mss photos stuff svn
books_tests Desktop1 downloads images notes scripts svgs

Source-code listings are also set in mono-spaced roman but add syntax highlighting as follows:

Preface

static

int

kvm_vm_ioctl_deassign_device(

struct

kvm *kvm,

struct

kvm_assigned_pci_dev *assigned_dev)

{

int

r = 0;

struct

kvm_assigned_dev_kernel *match;

mutex_lock(&kvm->lock);

match = kvm_find_assigned_dev(&kvm->arch.assigned_dev_head,
assigned_dev->assigned_dev_id);

(!match) {

printk(KERN_INFO

"%s: device hasn't been assigned before, "

"so cannot be deassigned

, __func__);

r = -EINVAL;

goto

out;

}

kvm_deassign_device(kvm, match);

kvm_free_assigned_device(kvm, match);

out:
mutex_unlock(&kvm->lock);

return

}

1.3. Notes and Warnings

Finally, we use three visual styles to draw attention to information that might otherwise be overlooked.

Note

Notes are tips, shortcuts or alternative approaches to the task at hand. Ignoring a note should
have no negative consequences, but you might miss out on a trick that makes your life easier.

Important

Important boxes detail things that are easily missed: configuration changes that only apply to the
current session, or services that need restarting before an update will apply. Ignoring a box
labeled “Important” will not cause data loss but may cause irritation and frustration.

Warning

Warnings should not be ignored. Ignoring warnings will most likely cause data loss.

Preface

Chapter 1. About the Command Line Interface

1.1. Introduction to the Command Line Interface

The Red Hat Enterprise Virtualization suite features a command line interface (CLI). This CLI provides
users with a means to connect to Red Hat Enterprise Virtualization Manager outside of the standard web
interface. The CLI also contains a scripting system, which helps system administrators perform periodic
maintenance or repetitive tasks on their virtualization environment via client machines.

Report a bug

Red Hat Enterprise Virtualization 3.3 Command Line Shell Guide

Chapter 2. Using the CLI

2.1. Installing the CLI

Install the Red Hat Enterprise Virtualization CLI to a client machine:

1. Log into the client machine as the root user.
2. Subscribe to the Red Hat Enterprise Virtualization Manager Channels:

Subscription Manager instructions

# subscription-manager list --available | grep -A8 "Red Hat Enterprise
Virtualization"
# subscription-manager subscribe --pool=POOLID
# yum-config-manager --enablerepo=rhel-6-server-rhevm-3.3-rpms

RHN Classic instructions

# rhn_register
# rhn-channel --add --channel=rhel-x86_64-server-6-rhevm-3.3

Note

See the Red Hat Enterprise Virtualization Manager Release Notes for specific channel
names current to your system.

3. Install the CLI package and dependencies:

# yum install rhevm-cli

Report a bug

2.2. TLS/SSL Certification

The Red Hat Enterprise Virtualization Manager API requires Hypertext Transfer Protocol Secure
(HTTPS)

for secure interaction with client software, such as the Manager's SDK and CLI components.

This involves a process of obtaining a certificate from the Red Hat Enterprise Virtualization Manager and
importing it into the certificate store of your client.

Important

Obtain your certificate from the Red Hat Enterprise Virtualization Manager using a secure network
connection.

Procedure 2.1. Obtaining a Certificate

You can obtain a certificate from the Red Hat Enterprise Virtualization Manager and transfer it to the
client machine using one of three methods:

[1]

Chapter 2. Using the CLI

1. Method 1 - Use a command line tool to download the certificate from the Manager. Examples of

command line tools include cURL and Wget, both of which are available on multiple platforms.

a. If using cURL:

$ curl -o rhevm.cer http://[rhevm-server]/ca.crt

b. If using Wget:

$ wget -O rhevm.cer http://[rhevm-server]/ca.crt

2. Method 2 - Use a web browser to navigate to the certificate located at:

http://[rhevm-server]/ca.crt

Depending on the chosen browser, the certificate either downloads or imports into the browser's
keystore.

a. If the browser downloads the certificate: save the file as rhevm.cer.

If the browser imports the certificate: export it from the browser's certification options and
save it as rhevm.cer.

3. Method 3 - Log in to the Manager, export the certificate from the truststore and copy it to your

client machine.

a. Log in to the Manager as the root user.
b. Export the certificate from the truststore using the Java keytool management utility:

$ keytool -exportcert -keystore /etc/pki/ovirt-engine/.truststore -alias
cacert -storepass mypass -file rhevm.cer

This creates a certificate file called rhevm.cer.

c. Copy the certificate to the client machine using the scp command:

$ scp rhevm.cer [username]@[client-machine]:[directory]

Each of these methods results in a certificate file named rhevm.cer on your client machine. An API
user imports this file into the certificate store of the client.

Procedure 2.2. Importing a Certificate to a Client

Importing a certificate to a client relies on how the client itself stores and interprets certificates. This
guide contains some examples on importing certificates. For clients not using Network Security
Services (NSS) or Java KeyStore (JKS), see your client documentation for more information on
importing a certificate.

Report a bug

2.3. Running the CLI

Start the CLI application with the following command:

# rhevm-shell

This rhevm-shell application is an interactive shell for Red Hat Enterprise Virtualization environments.

Red Hat Enterprise Virtualization 3.3 Command Line Shell Guide

Users connect automatically to Red Hat Enterprise Virtualization Manager using the following additional
options.

# rhevm-shell -c -l "https://[server]/api" -P [port] -u "[user@domain]" -A
"[certificate]"

Ensure to replace the following values:

server - The hostname or IP Address of the Red Hat Enterprise Virtualization Manager. The CLI
connects to the Red Hat Enterprise Virtualization Manager via the REST API.
user@domain - The user name and directory service domain for the user logging into Red Hat
Enterprise Virtualization Manager.
certificate - The path name of the Certificate Authority file.

The shell will prompt you for the password, and, if not already provided, the use rname and the URL for
the Red Hat Enterprise Virtualization Manager.

Note

The certificate is the only obligatory option as the others used in this example will be prompted by
the shell. Instead of specifying the certificate you can use the '--insecure' option to connect
without certification, however this is not recommended as it may allow man-in-the-middle (MITM)
attackers to spoof the identity of the server.

Options for rhevm-shell

-h, --help

Show help for rhevm-shell.

-d, --debug

Enables debugging.

-l URL, --url=URL

Specifies the API entry point URL.

-u USERNAME, --username=USERNAME

Connect as this user.

-K KEY_FILE, --key-file=KEY_FILE

Specify key file.

-C CERT_FILE, --cert-file=CERT_FILE

Specify certificate file.

-A CA_FILE, --ca-file=CA_FILE

Specify server Certificate Authority file.

Chapter 2. Using the CLI

-I, --insecure

Allow the CLI to connect via SSL without certification. Use this option with caution because it can
allow man-in-the-middle (MITM) attackers to spoof the identity of the server.

-F, --filter

Enable filtering based upon user permissions.

-P PORT, --port=PORT

Specify port.

-T TIMEOUT, --timeout=TIMEOUT

Specify timeout.

-c, --connect

Automatically connect.

-f FILE, --file=FILE

Read commands from FILE instead of stdin.

-e, --extended-prompt

Enables the extended prompt option for the shell. This option displays the hostname of the
environment in the command prompt. Default is 'false'.

Note

Although users can use the --file option to call a file that includes their password information, this
practice is not recommended for security reasons. Users with a non-interactive shell are able to
connect to the Red Hat Enterprise Virtualization Manager from within the shell, where the --
password option can be used.

Report a bug

2.4. Interacting with the CLI

The CLI is an interactive shell for controlling your Red Hat Enterprise Virtualization environment from the
command line. Type the required command and any additional parameters.

Example 2.1. Entering a shell command

[RHEVM shell (connected)]# show vm --name desktop_vms

To support the construction of command and parameter combinations, the CLI includes the functionality
to list and automatically complete commands and parameters by pressing the TAB key twice, similar to

Red Hat Enterprise Virtualization 3.3 Command Line Shell Guide

the bash shell.

Example 2.2. Listing and automatic completion of commands and parameters

Press double TAB at a blank prompt to list all available commands.

[RHEVM shell (connected)]# TAB TAB
EOF clear console remove echo file
history ping show update action connect
add disconnect exit help list shell
status

Choose a command and press double TAB to view the next set of available parameters for the
command. For the show, this lists all resources.

[RHEVM shell (connected)]# show TAB TAB
brick datacenter event group nic
quota statistic template vmpool cdrom
disk file host permission role
storagedomain user cluster domain glustervolume
network permit snapshot tag vm

Double TAB also completes commands and parameters.

[RHEVM shell (connected)]# show vm TAB TAB
kwargs name show-all storagedomain
[RHEVM shell (connected)]# show vm naTAB TAB
[RHEVM shell (connected)]# show vm --name

Note that the double TAB also automatically formats na to the --name parameter, including the
prefix.

If the incomplete parameter matches multiple parameters, double TAB lists them.

[RHEVM shell (connected)]# show vTAB TAB
vmpool vm

The CLI provides functions to run Linux commands using either the shell command or the bang (!)
character.

Example 2.3. Running Linux shell commands

Use the shell command:

[RHEVM shell (connected)]# shell ls -la

Or use the bang (!) character:

[RHEVM shell (connected)]# !ls -la

Similar to the Linux shell, the CLI can pipe data to other commands and sources.

Chapter 2. Using the CLI

Example 2.4. Piping CLI commands

Pipe CLI data to a Linux shell command:

[RHEVM shell (connected)]# list vms --show-all | grep "Example"
name : Example1
name : Example2
name : ExampleEngineering
description : An Example description
name : BestExampleVM

Pipe CLI data to a file:

[RHEVM shell (connected)]# list vms --show-all > list vms --show-all >
VM_List.txt

The CLI also contains an online help system to provide descriptions and syntax for each command via
the help command.

Example 2.5. Using online help for the show command

[RHEVM shell (connected)]# help show

Report a bug

2.5. Collections

Some command parameters require a collection. A collection is a set of sub-parameter data. Collections
are defined using the following syntax.

[RHEVM shell (connected)]# command --param-collection
{subparam1=value1;subparam2=value2;subparam3=value3;...},{subparam1=value1;subparam2
=value2;subparam3=value3;...},...

Sub-parameters for collections are listed after resource parameter listings on each resource page.

Chapter 3. Quick Start Example

3.1. Creating a Basic Virtualization Environment with the CLI

This chapter provides an example to demonstrate the CLI's ability to add a virtual machine within a basic
Red Hat Enterprise Virtualization environment. This example uses the following prerequisites:

A networked and configured Red Hat Enterprise Linux host for use as a hypervisor;
A networked and configured NFS storage server with two shares:

/exports/data - The data storage domain; and
/exports/iso - The ISO storage domain.

A networked and configured Red Hat Enterprise Virtualization Manager;
An installation of the CLI on either the Red Hat Enterprise Virtualization Manager or a client machine;
and,
An ISO file containing a desired virtual machine operating system to install. This chapter uses Red
Hat Enterprise Linux Server 6 for our installation ISO example.

Note

Red Hat Enterprise Virtualization Manager generates a globally unique identifier (GUID) each
resource's ID. Identifier codes in this example might appear different to the identifier codes in your
Red Hat Enterprise Virtualization environment.

Procedure 3.1. Quick Start Example

1. Load the CLI shell and connect to your Red Hat Enterprise Virtualization Manager

The following step run the CLI shell command with additional parameters to connect to your
virtualization environment.

# rhevm-shell -c --url https://[rhevm-host]/api --username [user]@[domain] -
-ca-file certificate/authority/path/name

2. List data centers

Red Hat Enterprise Virtualization Manager adds a Default data center on installation. This
example uses the Default data center as the basis for our virtual environment.

[RHEVM shell (connected)]# list datacenters

id : 5e3b55d8-c585-11e1-a7df-001a4a400e0d
name : Default
description: The default Data Center

3. List host clusters

Red Hat Enterprise Virtualization Manager adds a Default host cluster on installation. This
example uses the Default cluster to group resources in your Red Hat Enterprise Virtualization
environment.

Chapter 3. Quick Start Example

[RHEVM shell (connected)]# list clusters

id : 99408929-82cf-4dc7-a532-9d998063fa95
name : Default
description: The default server cluster

4. List logical networks

Red Hat Enterprise Virtualization Manager creates a default logical network called rhevm for
management traffic. This example uses the rhevm logical network on the Default data center.

[RHEVM shell (connected)]# list networks --show-all

id : 00000000-0000-0000-0000-000000000009
name : rhevm
description : Management Network
data_center-id: 5e3b55d8-c585-11e1-a7df-001a4a400e0d
mtu : 0
required : True
status-state : operational
stp : False
usages-usage : VM

Note the data_center-id value matches the id for the Default data center.

5. Create host

Use the add host command to add the Red Hat Enterprise Linux host to the virtualization
environment as a new hypervisor. Name this host MyHost.

[RHEVM shell (connected)]# add host --name MyHost --address host.example.com
--root_password p@55w0rd!

Ensure to substitute address and root_password with the correct values from your host.

6. Activate host

Activate the host after creation using the action host command.

[RHEVM shell (connected)]# action host MyHost activate

7. Create NFS data storage

An NFS data storage domain is an exported NFS share attached to a data center. It provides
storage for virtual machines. Add the NFS share as a data storage domain with the add
storagedom ain command.

[RHEVM shell (connected)]# add storagedomain --name DataStorage --host-name
MyHost --type data --storage-type nfs --format v1 --storage-address
'192.168.0.10' --storage-path /exports/data --datacenter-identifier Default

Ensure to substitute storage-address and storage-path with the correct values from your
NFS server.
Note the datacenter-identifier option attaches the storage domain to the Default data
center as a sub-resource.
After creation, use the action storagedomain to activate the storage domain.

Red Hat Enterprise Virtualization 3.3 Command Line Shell Guide

[RHEVM shell (connected)]# action storagedomain DataStorage activate

8. Create NFS ISO storage

An NFS ISO storage domain is an exported NFS share attached to a data center. It provides
storage for DVD/CD-ROM ISO and virtual floppy disk (VFD) image files. Add the NFS share as an
ISO storage domain with the add storagedomain command.

[RHEVM shell (connected)]# add storagedomain --name ISOStorage --host-name
MyHost --type iso --storage-type nfs --format v1 --storage-address
'192.168.0.10' --storage-path /exports/iso --datacenter-identifier Default

[RHEVM shell (connected)]# action storagedomain ISOStorage activate

9. Create virtual machine

Use the add vm command to add a new virtual machine.

[RHEVM shell (connected)]# add vm --name MyVM --cluster-name Default --
template-name Blank --memory 536870912 --os-boot-dev hd

10. Create virtual machine network interface

Use the add nic command to add a new network interface. Add the vm-identifier option to
attach the interface as a sub-resource of MyVM and a network-name option to connect to the
rhevm network.

[RHEVM shell (connected)]# add nic --vm-identifier MyVM --name nic1 --
network-name rhevm --bootable true

11. Create virtual machine hard disk

Use the add disk command to add a new virtual hard disk. Add the vm-identifier option to
attach the disk as a sub-resource of MyVM.

[RHEVM shell (connected)]# add disk --vm-identifier MyVM --provisioned_size
8589934592 --interface virtio --format cow

12. Add virtual machine CD-ROM drive

The boot media for our example virtual machine requires an CD-ROM or DVD ISO image for an
operating system installation. This example uses a Red Hat Enterprise Server 6 ISO image for
installation.
ISO images must be available in the ISOStorage domain for the virtual machines to use. Red
Hat Enterprise Virtualization Manager provides an ISO uploader tool that ensures images are
uploaded into the correct directory path with the correct user permissions. Once uploaded, use the
list files to show files in the storage domain.

[RHEVM shell (connected)]# list files --storagedomain-identifier

Chapter 3. Quick Start Example

Use the add cdrom command to add a new virtual CD-ROM for your installation media. Add the
vm -identifier option to attach the CD-ROM as a sub-resource of MyVM.

[RHEVM shell (connected)]# add cdrom --vm-identifier MyVM --file-id rhel-
server-6.0-x86_64-dvd.iso

13. Start virtual machine

The virtual environment is complete and the virtual machine contains all necessary components to
function. Start the virtual machine with the action vm command.

[RHEVM shell (connected)]# action vm start --vm-os-boot-dev cdrom

Note the use of the vm-os-boot-dev option. This changes the boot device to cdrom for this
initial boot session. After installation, the virtual machine restarts and restores the boot device back
to hd.

14. List Events

The start action for the virtual machine adds several entries in the events collection. Use the
list events with an additional query to display the events.

[RHEVM shell (connected)]# list events --query "type=153"

id : 105
description: MyVM was started by admin (Host: MyHost).

The "type=153" query refers to events where a user starts a virtual machine.

15. Show Event

Use show event to display comprehensive details of an event. This command can be used to
show events by type, name and id.

[RHEVM shell (connected)]# show event --id 60

id : 60
description : New Tag foo was created by admin@internal.
code : 432
correlation_id: 3e4d4350
custom_id : -1
flood_rate : 30
origin : oVirt
severity : normal

user-id : fdfc627c-d875-11e0-90f0-83df133b58cc

16. Access Virtual Machine

Access your virtual machine with the console command.

[RHEVM shell (connected)]# console MyVM

Important

Ensure your client machine has a console application installed to match the virtual
machine's display-type. Protocols available include SPICE (default) and VNC.

Chapter 6. CLI Queries

6.1. Query Syntax

The CLI list command uses the --query attribute to perform server-side queries, which uses the
same format as Red Hat Enterprise Virtualization Manager search query language:

Table 6.1. Example search queries

Collection

Criteria

Result

hosts

vm s.status=up

Displays a list of all hosts
running virtual machines that
are up.

vm s

dom ain=qa.com pany.com

Displays a list of all virtual
machines running on the
specified domain.

vm s

users.nam e=m ary

Displays a list of all virtual
machines belonging to users
with the user name mary.

events

severity>norm al sortby
tim e

Displays the list of all events
with severity higher than
norm al and sorted by the
tim e element values.

events

severity>norm al sortby
tim e desc

Displays the list of all events
with severity higher than
norm al and sorted by the
tim e element values in
descending order.

Report a bug

6.2. Wildcards

Search queries substitute part of a value with an asterisk as a wildcard.

Example 6.1. Wildcard search query for name=vm*

[RHEVM shell (connected)]# list vms --query "name=vm*"

This query would result in all virtual machines with names beginning with vm, such as vm1, vm2, vma
or vm-webserver.

Example 6.2. Wildcard search query for name=v*1

[RHEVM shell (connected)]# list vms --query "name=v*1"

This query would result in all virtual machines with names beginning with v and ending with 1, such as
vm 1, vr1 or virtualm achine1.
