For the record, we have realized that this failure is unrelated to the log supplied in bug https://bugzilla.redhat.com/show_bug.cgi?id=1417595 . That log is due to a test requesting dhcp address, not receiving it, and carrying on to next tests, while a Vdsm thread is still waiting for dhcp. The cause for this breakage is probably a broken jsonrpc connection, hopefully fixed by https://gerrit.ovirt.org/#/q/Idaa54767bb7e54bf13e89887ca34fa8e01ade420 On Thu, Mar 9, 2017 at 3:06 PM, Dan Kenigsberg <danken@redhat.com> wrote:

Yes, this seems to be a reproduction of Vdsm bug 1417595 - hotplug_nic test fails in OST
Eddy, can you tell how could it be that the VLAN100_NETWORK bridge does not exist when ifup is called?
