These are the current steps we followed to set up and run Windows P2V migrations. Note
that development is proceeding rapidly and the versions of all pieces below will likely be
obsolete soon.

Windows RHEV P2V Cookbook 2011-1122
1. Install 32 bit Fedora 14 as a virtual machine or physical host. You will use this
system to
build a .ISO file to burn to CD. Later in the process, you'll boot a source physical
machine from
this CD.
2. Install 64 bit Fedora 16 as another virtual machine or physical host. This will
become your migration
server.
3 - Download and install virt-v2v on both the 32 and 64 bit systems. (yum install
virt-v2v).
Virt-v2v is a package to migrate virtual machines from one virtual environment to either
libvirt or RHEV. It
also includes the P2V extensions.
4 - Download, install, and run virt-p2v-image-builder (yum install virt-p2v-image-builder)
on the 32 bit
system. virt-p2v-image-builder is a tool that builds a .ISO file for source physical
machines to boot from.
Do this on the 32 bit system so it builds a 32 bit kernel so you can use it to boot 32 bit
hardware. Burn the
.ISO file to a CD. You won't need the 32 bit system any more.
All subsequent Fedora operations will happen on the 64 bit system.
5. On the 64 bit Fedora system, edit /etc/yum.repos.d/fedora-updates-testing.repo; change
"enabled=0" to
"enabled=1"
6. yum install and/or update libguestfs. This downloads and installs
libguestfs-1.14.2-1.fc16.x86_64 and all
its dependencies. (Much easier than downloading all the RPMs by hand.)
7. Go to the link Matt provided:
http://koji.fedoraproject.org/koji/taskinfo?taskID=3531688
and install Matt's temporary bleeding edge version of virt-v2v. Edit
/usr/bin/virt-p2v-server and uncomment
the line setting $ENV{'LIBGUESTFS_TRACE'} = 1;
7 - Edit the target profile on the Fedora system (/etc/virt-v2v.conf). This describes the
environment to
migrate into. The .conf file is separated into sections. Copy the appropriate section,
paste it in the
bottom, remove the comment markers, and customize with correct names of objects for this
site.
8. From RHEL 6 supplementary RHN channel or other suitable source, download and install a
copy of virtio-win-
1.3.3-0.el6.noarch.rpm on the Fedora migration server.
9. Install libguestfs-winsupport on a RHEL 6.1 or newer system. On that RHEL 6 system
do:
cd /var/lib/virt-v2v/software
tar -cvf firstboot.tar windows
10. Copy firstboot.tar to /var/lib/virt-v2v/software on the Fedora migration server.
11. On the Fedora migration server:
cd /var/lib/virt-v2v/software
tar -xvf firstboot.tar
This should set up the following:
[root@Fedora16-64P2V software]# pwd
/var/lib/virt-v2v/software
[root@Fedora16-64P2V software]# ls -al -R
.:
total 4312
drwxr-xr-x. 3 root root 4096 Nov 22 10:49 .
drwxr-xr-x. 3 root root 4096 Nov 22 10:25 ..
-rw-r--r--. 1 root root 4403200 Nov 22 10:48 firstboot.tar
drwxr-xr-x. 2 root root 4096 Jun 23 05:53 windows
./windows:
total 4304
drwxr-xr-x. 2 root root 4096 Jun 23 05:53 .
drwxr-xr-x. 3 root root 4096 Nov 22 10:49 ..
-rw-r--r--. 1 root root 994 Feb 14 2011 firstboot.bat
-rw-r--r--. 1 root root 4324584 Feb 14 2011 rhev-apt.exe
-rw-r--r--. 1 root root 68928 Feb 14 2011 rhsrvany.exe
[root@Fedora16-64P2V software]#
12. Now try a P2V. Boot the source Windows system from the CD created earlier, connect to
the Fedora
migration server IP Address, select the profile you made and start the migration. This
should create a
virtual machine and virtual disk images in the RHEV Exports staging area.
13. When the migration finishes, use RHEV Manager to import the newly migrated virtual
machine into the RHEV
environment.
