[ovirt-users] Problem with hosted engine setup on VLAN/bond combo

[Chris Adams]

I am trying to install oVirt with the hosted engine.  The physical
system is CentOS 6.5 x86_64 (with all current updates).  It is connected
to a two-switch stack via bond0 (running LACP), which is a VLAN trunk,
and the management interface is vlan51.

This doesn't work with oVirt 3.4.2, but I see that both 3.4.3 and 3.5
have "support engine on bond" and "support engine on vlan" in the
release notes, so I tried again with today's 3.4.3 RC.  I got a
different error from "hosted-engine --deploy":

[ ERROR ] Failed to execute stage 'Misc configuration': Command '/usr/bin/vdsClient' failed to execute

I see this in /var/log/vdsm/supervdsm.log:

Is there maybe still a problem combining a VLAN on a bond?


A little background (if it helps): this is my first attempt with oVirt.
I'm installing on a clean CentOS install on a spare box, with the intent
to get oVirt up and running and then convert (one node at a time) an
existing VM setup (running old stand-alone Xen installs) to oVirt.
