Open Stack

Hi,

You are right Robson.
I tried to convert XVA to Qcow2, it was successful but when I launched VM
on KVM, it was not booting.
Then I converted OVF/OVA to Qcow2, and this time when I launched it in KVM,
it came up successfully.

I don't have any clue why it didn't worked with XVA format ?
