Hm - I've been able to successfully perform an Karmic -server install using raw files as the backend.

Could you give more information about the guest configuration?

Which release? Which kernel version is it running (uname -a)?

How are you running the guest? Via kvm or libvirt?

If you're using kvm could you provide the command line you're using?

If you're using libvirt could you provide the xml definition of the guest
(virsh dumpxml guest-name) as well as the kvm command line launched by libvirt
(ps -ef)?

Are these new raw files or existing raw files?
