Greetings,

I am trying to use virtio and encryption.

My setup is:
host and guest: ubuntu 10.04 server (libvirt 0.7.5-5ubuntu27, qemu-kvm
0.12.3+noroms-0ubuntu9.2)
I have secret defined and disk in domain xml referencing that secret.

When I start using "<target dev='hda' bus='ide'/>" in HDD config, it works.
When I start using "<target dev='vda' bus='virtio'/>" I get following in syslog:

qemuMonitorCommandWithHandler:240 : cannot send monitor command
'cont': Unknown error  8446744073709551594

running with  "<target dev='vda' bus='virtio'/>" works fine if format
is raw and there is no encryption.

Is storing raw images on encrypted loop device the only way to have
both virtio and ecryption?
