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.
virt-p2v-make-disk has two required parameters:
The -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.
The "os-version" parameter is the base Linux distro to use for the operating system on the ISO. To list possible "os-version" combinations, do:
EXAMPLESWrite a virt-p2v bootable USB key on /dev/sdX (any existing content is erased), using Fedora 20 as the base distribution:
virt-p2v-make-disk -o /dev/sdX fedora-20
Write a virt-p2v bootable virtual disk image, and boot it under qemu:
virt-p2v-make-disk -o /var/tmp/p2v.img fedora-20 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 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.
- -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.
- 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.
