virt-p2v-make-disk - Build the virt-p2v disk using virt-builder
virt-p2v-make-disk -o /dev/sdX [os-version]
DESCRIPTIONvirt-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 parameterThe 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:
EXAMPLESWrite 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
ADDING EXTRA PACKAGESYou 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 IDENTITYYou 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:
For more information, see ``SSH IDENTITIES'' in virt-p2v(1).
- 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.
- 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.
- Enable verbose output. Use this if you need to debug problems with the script or if you are filing a bug.
- Display version number and exit.
The virt-p2v(1) binary which is copied into the bootable disk
The location of the binary can be changed by setting the "VIRT_P2V_DATA_DIR" environment variable.
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.
- The directory where virt-p2v-make-disk looks for data files (see ``FILES'' above). If not set, a compiled-in location is used.
