Description

Hi all!

There is an old bug in library fog-libvirt, which is used by foreman to get information about libvirt networks: https://github.com/fog/fog-libvirt/issues/24

If there is a network without "bridge" parameter present, e.g. pool of virtual functions on NIC - almost every operation on this compute resource throws an error:

Call to virNetworkGetBridgeName failed: internal error: network 'libvirt-network-name' does not have a bridge name.

I cannot create any VM or import existing VMs.

I believe such networks are not supported by Foreman.
But maybe it's possible to handle such error and ignore this network. So user will be able to work with this compute resource using other networks.

Best regards,
Vyacheslav Spiridonov

The fix really needs to go to fog-libvirt. If we add rescue, we won't load any network and the compute resource would be basically unsuable anyway. We only load all network at once, which fails on fog-libvirt side. It seems it can be easily fixed in fog-libvirt though, so I'm opening a PR there - https://github.com/fog/fog-libvirt/pull/78. If it's accepted, we just need to bump fog-libvirt dependency in Foreman.
