Installing MAAS using 15.04 server ISO (amd64) on remote machine via virt-manager results in black screen

[Alexander List]

What I did:

* Set up a box as VM host for manually provisioned VMs (using ssh and virt-manager)
* Created a new VM using the 15.04 server ISO (amd64)
* Select "multiple host install using MAAS"
* made this VM a standalone MAAS

After installation finishes the VM reboots, and the remote console in virt-manager remains black, or displays garbage. I can log in via ssh tho.

Trying the same with a vanilla Ubuntu Server install works, I get a functional remote console in virt-manager.
