[libvirt] 0.8.8 and virtio console



Hi all,

This used to work on libvirt-0.8.7:

<console type='pty'>
    <target type='virtio'/>
</console>

Using the same configuration with libvirt-0.8.8:

[root ev004 ~]# virsh create /data/4d5d8a24-bb70-4eff-b1b5-3d8e5bd5c355.xml
error: Failed to create domain from
/data/4d5d8a24-bb70-4eff-b1b5-3d8e5bd5c355.xml
error: internal error no assigned pty for device console0

I'm using qemu-kvm-0.14.0-0.1.201102107aa8c46.

Here's the log from starting a guest with 0.8.7:
