Problem with hosted engine setup on VLAN/bond combo
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: ######################################################################## MainProcess|Thread-16::INFO::2014-07-10 10:20:23,003::configNetwork::275::root::(addNetwork) Adding network ovirtmgmt with vlan=51, bonding=None, nics=['bond0'], bondingOptions=None, mtu=None, bridged=True, defaultRoute=True,options={'bootproto': 'static', 'ONBOOT': 'yes'} MainProcess|Thread-16::ERROR::2014-07-10 10:20:23,003::supervdsmServer::100::SuperVdsm.ServerCallback::(wrapper) Error in addNetwork Traceback (most recent call last): File "/usr/share/vdsm/supervdsmServer", line 98, in wrapper res = func(*args, **kwargs) File "/usr/share/vdsm/supervdsmServer", line 190, in addNetwork return configNetwork.addNetwork(bridge, **options) File "/usr/share/vdsm/configNetwork.py", line 186, in wrapped return func(*args, **kwargs) File "/usr/share/vdsm/configNetwork.py", line 287, in addNetwork blockingdhcp=blockingdhcp, **options) File "/usr/share/vdsm/configNetwork.py", line 121, in objectivizeNetwork topNetDev = Nic(nic, configurator, mtu=mtu, _netinfo=_netinfo) File "/usr/share/vdsm/netmodels.py", line 80, in __init__ raise ConfigNetworkError(ne.ERR_BAD_NIC, 'unknown nic: %s' % name) ConfigNetworkError: (23, 'unknown nic: bond0') ######################################################################## 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. -- Chris Adams <cma@cmadams.net>

(see http://www.ovirt.org/Installing_VDSM_from_rpm#Configuring_the_bridge_Interf= ace) I set up my 3.4.2 ovirtmgmt interface as a bridge to a vlan before installation, and it worked fine.

Yes exactly, but just with hosted-engine. See this BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1072027 (Should be resolved with 3.5) There is also a workaround in the BZ, didn't try it myself.

Well, the same notes are in the 3.4.3 release notes as 3.5: oVirt Hosted Engine Setup BZ 1111162 - [RFE] [ovirt-hosted-engine-setup] add support for bonded interfaces BZ 1117634 - [RFE] Hosted Engine deploy should support VLAN-tagged interfaces Since I got a different error when I tried 3.4.3-RC vs. 3.4.2 (and I'm trying with a VLAN on top of a bond), I was concerned that the same fix as 3.5 was in 3.4.3-RC, and would not actually fix my combo setup.
There is also a workaround in the BZ, didn't try it myself.
Yeah, I can't (easily anyway) disable the VLAN trunk and bond and then re-enable them (since that breaks network access, and I'm not sitting at the same location as the system). I will try Robert Story's suggestion of manually configuring the bridge before running the deploy. -- Chris Adams <cma@cmadams.net>
