NAME

virt-p2v-make-disk - Build the virt-p2v disk using virt-builder

SYNOPSIS

 virt-p2v-make-disk -o /dev/sdX [os-version]

DESCRIPTION

virt-p2v(1) converts a physical machine to run virtualized on KVM, managed by libvirt, OpenStack, oVirt, Red Hat Enterprise Virtualisation (RHEV), or one of the other targets supported by virt-v2v(1).

virt-p2v-make-disk is a script which creates a bootable disk image or USB key containing virt-p2v. It uses virt-builder(1) to do this, and is just a small shell script around virt-builder.

The required -o parameter specifies where the output should go, for example to a USB key (eg. "-o /dev/sdX") or to a file. If you pass a device name, then the existing contents of the device will be erased.

os-version parameter

The optional "os-version" parameter is the base Linux distro to use for the operating system on the ISO. If you don't set this parameter, the script tries to choose a suitable default for you. Most users should not use the "os-version" parameter.

The base OS selected for virt-p2v is not related in any way to the OS of the physical machine that you are trying to convert.

To list possible "os-version" combinations, do:

 virt-builder -l

EXAMPLES

Write a virt-p2v bootable USB key on /dev/sdX (any existing content on /dev/sdX is erased):

 virt-p2v-make-disk -o /dev/sdX

Write a virt-p2v bootable virtual disk image, and boot it under qemu:

 virt-p2v-make-disk -o /var/tmp/p2v.img
 qemu-kvm -m 1024 -boot c \
   -drive file=/var/tmp/p2v.img,if=virtio,index=0 \
   -drive file=/var/tmp/guest.img,if=virtio,index=1

where /var/tmp/guest.img would be the disk image of some guest that you want to convert (for testing only).

ADDING EXTRA PACKAGES

You can install extra packages using the --install option. This can be useful for making a more fully-featured virt-p2v disk with extra tools for debugging and troubleshooting. Give a list of packages, separated by commas. For example:

 virt-p2v-make-disk -o /var/tmp/p2v.img --install tcpdump,traceroute

ADDING AN SSH IDENTITY

You can inject an SSH identity (private key) file to the image using the --inject-ssh-identity option.

First create a key pair. It must have an empty passphrase:

 ssh-keygen -t rsa -N '' -f id_rsa

This creates a private key ("id_rsa") and a public key ("id_rsa.pub") pair. The public key should be appended to the "authorized_keys" file on the virt-v2v conversion server (usually to "/root/.ssh/authorized_keys").

The private key should be injected into the disk image and then discarded:

 virt-p2v-make-disk [...] --inject-ssh-identity id_rsa
 rm id_rsa

When booting virt-p2v, specify the URL of the injected file like this:

 │         User name: [root_____________________________] │
 │                                                        │
 │          Password: [    <leave this field blank>     ] │
 │                                                        │
 │  SSH Identity URL: [file:///var/tmp/id_rsa___________] │

or if using the kernel command line, add:

 p2v.identity=file:///var/tmp/id_rsa

For more information, see ``SSH IDENTITIES'' in virt-p2v(1).

OPTIONS

--help
Display help.
--inject-ssh-identity id_rsa
Add an SSH identity (private key) file into the image. See ``ADDING AN SSH IDENTITY'' above.
--install pkg,pkg,...
Add extra packages to the image. See ``ADDING EXTRA PACKAGES'' above.
--no-warn-if-partition
Normally you should not write to a partition on a USB drive (ie. don't use "-o /dev/sdX1", use "-o /dev/sdX" to make a bootable USB drive). If you do this, virt-builder prints a warning. This option suppresses that warning.
-o OUTPUT
--output OUTPUT
Write output to "OUTPUT", which can be a local file or block device. The existing contents of the device will be erased.
-v
--verbose
Enable verbose output. Use this if you need to debug problems with the script or if you are filing a bug.
-V
--version
Display version number and exit.

FILES

$libexecdir/virt-p2v
The virt-p2v(1) binary which is copied into the bootable disk image.

The location of the binary can be changed by setting the "VIRT_P2V_DATA_DIR" environment variable.

$datadir/virt-p2v/issue
$datadir/virt-p2v/launch-virt-p2v.in
$datadir/virt-p2v/p2v.service
Various data files that are copied into the bootable disk image.

The location of these files can be changed by setting the "VIRT_P2V_DATA_DIR" environment variable.

ENVIRONMENT VARIABLES

"VIRT_P2V_DATA_DIR"
The directory where virt-p2v-make-disk looks for data files (see ``FILES'' above). If not set, a compiled-in location is used.
