> Indira, are you or were you able to install 14.04 in the same host?
I have the same issue on on of my guests, netg3, so I can answer this.
When I start the 14.04 LTS install, I see two virtual disks listed in the partitioner questions. One disk is a 55GB virito-scsi disk (the intended root target disk) and the other is a 12GB virtio-block disk (intended for I/O tests).
When I start the 14.10 install, I only see the the 12GB virtio-block disk. The virtio-scsi root disk is not listed.
So, it is definitely possible to install 14.04 on the same guest disk where a 14.10 installation would fail.

I will do this for my KVM host. The relevant guest, in my case, is netg3.
