Hi,
I'm trying to add a channel on a Openstack instance via this command :
# virsh attach-device instance-00000005 test.xml
that returns this error
error: Failed to attach device from test.xml
error: internal error: no virtio-serial controllers are available
#
# cat test.xml :
<channel type='unix'>
<source mode='bind'
path='//var/lib/libvirt/qemu/instance-00000005.agent'/>
<target type='virtio' name='instance-00000005.agent'/>
</channel>
#virsh dumpxml instance-00000005
<domain type='kvm' id='8'>

How may I add this controller ( before adding the channel device) ?
Thanks for help.
