libvirt-bin: client network bridge (brX) not working

Post by peter_b »

[PROBLEM]
I have set up a VM-client (RHEL 6.6) on a Debian 7 host.
The Debian host had a working network bridge (eth0<>br0) configured, which was assigned as primary network adapter for the RHEL VM-client.

This used to always work without problems, but right now the VM-client didn't receive anything per DHCP, and manually assigning an IP address and then trying to ping the KVM-host also didn't work.
I couldn't find anything in any logs. Maybe there is, but I don't know :(


[SOLUTION]
I've restarted the networking on the KVM-host (Debian), while the "libvirt-bin" daemon was still running. This seems to have been the problem.
Run the following on the KVM host:

Code: Select all

$ sudo service libvirt-bin restart
After restarting libvirt-bin on the KVM-host and restarting the client (of course), the network was functional again :)
