Tried getting their qcow2 image running under proxmox but got stuck at "booting from hard disk..." prompt upon boot. Any thoughts on how to get this working?

Setup a new VM using Linux 3.2/2.6 OS (also tried Other OS), virtio disk of 20GB size, virt networking.

Overwrote original qcow2 file created by proxmox with downloaded OSV qcow2 image. Booted, but stuck at boot.

Thanks in advance for any help.
