I can see in the log that VDSM tried to obtain information about bond1
and (bridge) "Internet", both of which did not exist (yet?) in a
procedure which reports the information back to oVirt. But this just
means that no information about them was reported, it shows no real error.
There was no network configuration to be stored (persisted), this is why
the directories "/var/run/vdsm/netconf/nets" and
"/var/run/vdsm/netconf/bonds/" are not there.
If you use a static address/gateway, does the creation of the bond and
the network succeed in "Setup host networks"? If it does not I suggest
that you attach the whole logs.
