Public bug reported: Missing target device info makes it impossible to retrieve network usage information about a guest from libvirt.
Reproduce: Trigger of issue unknown. Workaround: Restart the guest, and the network device info reappears again. Detect: Use virsh with the dumpxml command to view information about a running guest. Good result: virsh # dumpxml myhost1 ... <interface type='bridge'> <mac address='52:54:00:11:a6:2c'/> <source bridge='br0'/> <target dev='vnet0'/> <model type='virtio'/> </interface> ... Bad result: virsh # dumpxml myhost2 ... <interface type='bridge'> <mac address='52:54:14:79:32:6d'/> <source bridge='br0'/> <model type='virtio'/> </interface> ... I am attaching an image of my munin graphs to illustrate the effects of the bug.
