Dear Michal: I'm sorry. The pasting XML I described earlier is wrong, and the real thing is: <interface type='bridge'> <mac address='52:54:00:0a:2b:2a'/> <source bridge='lcs_br_1'/> <virtualport type='openvswitch'/> <bandwidth> <inbound average='0' peak='0'/> <outbound average='0' peak='0'/> </bandwidth>
It doesn't make much sense to set these to zero. The domain will not be able to receive/send any packets through the interface. Also, this must be some older libvirt because when I try the latest git HEAD it doesn't even accept zero values there.
<model type='virtio'/> </interface>
I'm really sorry. I forgot I had QoS defined on the virtual machine. And this problem doesn't happen every time. I encountered this problem when I used the same XML to create about 100 virtual machines on a hypervisor.
This suggests it is a kernel problem. Michal
