Windows P2V migration temporary recipe
by Greg Scott
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.

[hivex][PATCH 2/8] generator: Add new return type to ABI: RLenValue
by Alex Nelson
RLenValue is similar to RLenType, though with one less argument. This
required adding additional conversion functions for several languages'
bindings.

P2Vs seem to require a very robust Ethernet
by Greg Scott
Now that we can gather diagnostic info, I think I know why our P2Vs kept
failing last week. Another one just died right in front of my eyes. I
think either the Ethernet or NFS server at this site occasionally
"blips" offline when it gets busy and that messes up P2V migrations.
The RHEV export domain is an NFS share offered by an old Storagetek NAS,
connected over a 10/100 Ethernet. All of us would prefer a gb Ethernet
but this is what we have available.
First, an extract from /var/log/messages showing the start and end times
for virt-p2v-server, about 3 1/2 hours.

Before it blew up, I was watching network usage of my RHEV host with the
Fedora migration server VM and it consistently pegged above 90%+. I've
never seen an Ethernet that saturated before. The iftop utility on my
Fedora guest migration server showed data consistently flying at 69-90+
Mb per second.

[PATCH] hivex: Added gnulib includes from builddir, as suggested by the Gnulib documentation; link hivexml against libgnu.
by Hilko Bengen
Since some modules (`getopt', for example) may copy files
into the build directory, `top_builddir/lib' is needed as well as
`top_srcdir/lib'. -- GNU Gnulib manual, section 2.2 Initial import
This fixes an in-tree build failure on a Debian/sid system (see
below). hivexml could be built out-of-tree, but it turned out that due
to a missing include path, in this case the system's getopt
implementation was used insted of Gnulib's.

following changes:
* Fixed whitespace error.
* Functions return -1 on error.

[PATCH] NFC: Cleanup iteration over fstab entries in inspect_fs_unix.c
by Matthew Booth
Select non-comment labels using an augeas path to return the correct nodes in
the first instance, rather than applying a regular expression to all results.
Iterate over returned matches using a char** iterator.
Use asprintf() to ensure the path string buffer is the correct size.

This isn't the right list for virt-v2v questions. That would be
libguestfs(a)redhat.com.
However the larger problem here is that doing offline conversions like
this isn't the way to use virt-v2v. Virt-v2v needs to connect to the
ESX server, and won't work in any other configuration.
