Looked at the system and VM. There are no error messages in the VM or in the host.
I was able to reproduce the problem with the XML. Infact, I removed cache=none and
io=native to see if it still happens. It does happen without those options.

It seems to be a ubuntu installer bug (nothing to do with PowerKVM).

Installer is able to partition the disk correctly. Use /dev/vda3 as a LVM partition.
It created a volume group and root volume correctly. After that it seems to fail.

I was able to access the partitions and root volume fine (with a shell):

~ # cat /proc/partitions

So, definitely a ubuntu installer bug.

Hi Badari,
Yes you are right , I used 21st sep iso build to install with LVM and it got installed without any issue.

????????????????????? [!!] Finish the installation ??????????????????????
? ?
?? Installation complete ?
?? Installation is complete, so it is time to boot into your new system. ?
?? Make sure to remove the installation media (CD-ROM, floppies), so ?
?? that you boot into the new system rather than restarting the ?
?? installation. ?
?? ?
?? <Go Back> <Continue> ?
? ?
?????????????????????????????????????????????????????????????????????????

Thanks...
Manas
