<div dir="ltr">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..)<div><br></div><div>thomas</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Mar 13, 2018 at 6:27 AM, Edward Haas <span dir="ltr"><<a href="mailto:ehaas@redhat.com" target="_blank">ehaas@redhat.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><br>OVS switch support is experimental at this stage and in some cases when trying to change from one switch to the other, it fails.<br>It was also not checked against a hosted engine setup, which handles networking a bit differently for the management network (ovirtmgmt).<br>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.<br><br></div>We plan to block cluster switch editing until these problems are resolved.

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

I'm getting this in vdsmd logs:<br>
