[Libguestfs] Windows P2V migration temporary recipe



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.
