[Bug 617778] [NEW] virtio breaks qcow encryption

[Mike Ponomarenko]

Public bug reported:

Binary package hint: qemu-kvm

virtio does not work witn encrypted qcow images.

host and guest: ubuntu 10.04.1 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.
