Hi,
would you mind sharing the whole vdsm.log and supervdsm.log?
Thanks,

Which version of oVirt?
Ovirt version is 4.2.3.5, vdsm version 4.20.27
How do you configured hosted engine to use openvswitch?
Did you follow the steps in

I've followed the same steps as outlined in that mail just that I
found it when I started to troubleshoot.
one cluster where the ovirt engine runs on the host,
there it works
What is the switch type of this cluster?
OVS
and when starting a vm the interface definition looks
like this:
<interface type="bridge">
<address bus="0x00" domain="0x0000"
function="0x0"
slot="0x03" type="pci" />
<mac address="00:1a:4a:16:01:51" />
<model type="virtio" />
<source bridge="vdsmbr_2XMhqdgD" />
<virtualport type="openvswitch" />
<filterref filter="vdsm-no-mac-spoofing" />
</interface>
Where do you pick up this xml?
From vdsm.log when the vm is created
The xml for that vm as fetched from vdsm does not contain
virtualport
Where do you pick up this xml, maybe from a logfile or virsh?
vdsm-client VM getInfo vmID=3efc0421-5ad5-4a04-9a0e-30bd8822b299
tag nor does it use the correct bridge, it looks like this:
<interface type="bridge">
<model type="virtio"/>
<link state="up"/>
<source bridge="ovirtmgmt"/>
<address bus="0x00" domain="0x0000" function="0x0"

I.e. somewhere the definition is modified to contain the
correct data
to work with openvswitch
On the other cluster where I try to run hosted engine I
don't get the

In the engine it's set to OVS, but at this point it hasn't
started yet. Does the host have that setting somewhere?
above behaviour. When the engine vm starts the interface
settings are
not modified to use the bridge in openvswitch, with the
result that
the vm fails to start:
Can you share the error message from engine.log and vdsm.log,
and maybe
supervdsm.log?
These are the error messages when vm fails to start, but it's
caused by the interface element does not contain virtualport nor
the correct bridge.
vdsm.log:

It's the hosted engine vm that fails to start, hence I don't have
any engine.log and supervdsm.log doesn't contain anything about this

I assumed first there is a hook that make the needed
change, but the
only hooks I can find that mentions openvswitch are
ovirt_provider_ovn_hook and 50_openstacknet but both
those would set
the source bridge to br-int and not look up the dynamic
name of the
bridge as created by vdsm.
One special thing about the host where I try to run
hosted engine is
that the there is a dummy port since otherwise I couldn't
get vdsm to
create the bridge, but that shouldn't affect changing the
interface
definition for the vm.
Where should I look next?
