virt-p2v was able to convert my centOS 5.2 physical machine to xen virtual machine and it runs great. Now, I am working on to convert this full virt machine to para virt .
Under my domU i have installed kernel-xen (since it is needed ) , and edited my grub menu to use the installed kernel.*
My grub menu file in domU looks like:
----kernel /vmlinuz-2.6.18-92.1.17.el5xen ro root=/dev/VolGroup00/LogVol00 rhgb quietinitrd /initrd-2.6.18-92.1.17.el5xen.img * * * * * * * * * * * * * * *
----
Here is my config file that I have used (for para):
-----name = "localhost_localdomain"uuid = "a57400f11c2138ec41087b80e813496e"
maxmem = 512memory = 512vcpus = 1bootloader = "/usr/bin/pygrub"disk = [ "file:/freespace/p2v-localhost_localdomain-200811061823-hda.img,hda,w" ]
vif = [ "mac=00:16:3e:e6:3b:e2" ]>>>#keymap = "en-us"#serial = "pty"
extra = "xencons=tty"bootloader = "/usr/bin/pygrub"vfb = [ *]vif = [ "mac=00:16:3e:17:03:9f,bridge=xenbr0" ]----
The error I am getting is:
--

converting full to para
I was using this process a few months back. Most likely what's happening
is that it's missing the disk controller modules in the in initrd so
it's not able to find your logical volumes. You'll will need to update
your /etc/modprobe.conf to use the paravirt modules (xennet/xenblk)
then rebuild the initrd. Should boot at that point.

I think you're missing the xenblk driver. * Try editing /etc/modprobe.conf to look like this:
