== Comment: #1 - Samuel Mendoza-Jonas <sjonas at au1.ibm.com> - ==
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.
