Re: [ovirt-users] ovirt 4.2.2-rc3 switching from legacy to OVS..

I'll work on it some more.  I have 2 different clusters in the data center (1 is the Hosted Engine systems, another is not..)  I had trouble with both.  I'll try again on the non-hosted engine cluster to see what it is doing.  I have it working in 4.1, but we are trying to do a clean wipe since the 4.1 engine has been upgraded so many times from v3.5 plus we want to move to hosted-engine-ha from a single engine node and the ansible modules/roles (which also have problems..) thomas On Tue, Mar 13, 2018 at 6:27 AM, Edward Haas <ehaas(a)redhat.com <mailto:ehaas@redhat.com>> wrote: OVS switch support is experimental at this stage and in some cases when trying to change from one switch to the other, it fails. It was also not checked against a hosted engine setup, which handles networking a bit differently for the management network (ovirtmgmt). Nevertheless, we are interested in understanding all the problems that exists today, so if you can, please share the supervdsm log, it has the interesting networking traces. We plan to block cluster switch editing until these problems are resolved. It will be only allowed to define a new cluster as OVS, not convert an existing one from Linux Bridge to OVS.

But it's a complete failure when I switch the cluster from Linux Bridge/Legacy to OVS.  The first time I try, vdsm does not properly configure the node, it's all messed up.
