Hi!

Ubuntu Server 12.04.3 don't boot on the Ubuntu Server 12.04.3 KVM Hypervisor.

I'm Try the KVM Hypervisor using Ubuntu Server 12.04.3.
But Not boot. Ubuntu Server 12.04.3 is a new installation.


What should I do?

But,Ubuntu Server 12.04.2(on Ubuntu Server 12.04.3 KVM) and Ubuntu Server 13.10(on Ubuntu Server 12.04.3 KVM) is working.
Well I’m not really sure what this is. ;)
