Thanks for the quick answer! Any particular uperf profile that was found to be more likely/reliably to trigger it? I assume with driver=qemu you actually mean something like: <interface type='network'> <source network='default'/> <model type='virtio'/> <driver name='qemu' Which is the only driver=qemu that makes sense for [1] I think. If you have a libvirt XML of the guest that was used somewhere could you please just attach it.
