= virtio notes

We have found that virtio is faster/more stable than emulating other
cards on our VMs.

To switch a VM to virtio:

* Remove from DNS if it's a proxy
* Log into the vm and shut it down
* Log into the virthost that the VM is on, and [.title-ref]#sudo virsh
edit <VM FQDN>#
* Add this line to the appropriate bridge interface(s):
+
....
<model type='virtio'/>
....
* Save/quit the editor
* [.title-ref]#sudo virsh start <VM FQDN>#
* Re-add to DNS if it's a proxy
