Did something happen in the last day or two that would have screwed up libvirt networking? I just started up a VM that I last ran on Sunday and it has suddenly developed issues with communication with the host machine. Call it VM1 and VMHOST (the libvirt network) and VMHOST_EXT VM1 ping -> Internet works VM1 ssh -> Internet works VM1 ping -> VMHost single ping goes through VM1 ssh -> VMHost works VMHOST_EXT ping -> VM1 works VMHOST_EXT ssh -> VM1 fails The only things that have changed were Ubuntu security updates to VMHOST (It is an Oneiric). The VM1 is intentionally kept unchanging to avoid breaking some software which will not work on newer releases (jaunty). Again, I was using the VM and mounting fs from VMHOST on it as recently as Sunday. Either there is something deep inside Ubuntu that has gotten deeply confused or someone has released an update that breaks things.

hi,all Does any of you know how to get the vnc port of a running vm through libvirt API instead of virsh vncdisplay ? I can't find any relevent API from libvirt, many thanks!
