Hi guys.

I have two problems since upgrading from 4.2.x to 4.3.4

First issue is I can no longer manually migrate VM's between hosts, I get an error in the ovirt GUI that says "Could not fetch data needed for VM migrate operation" and nothing gets logged either in my engine.log or my vdsm.log

Then the other issue is my Dashboard says the following "Error! Could not fetch dashboard data. Please ensure that data warehouse is properly installed and configured."

If I look at my ovirt-engine-dwhd.log I see the following if I try restart the dwh service...

I have a hosted engine, and I have two hosts and my storage is FC based. The hosts are still running on 4.2 because I'm unable to migrate VM's off.

I have plenty resources available in terms of CPU and Memory on the destination host, and my Cluster version is set to 4.2 because my hosts are still on 4.2

I have recently upgraded from 4.1 to 4.2 and then I upgraded my hosts to 4.2 as well, but I can't get my hosts to 4.3 because of the above migration issue.

I'm also seeing a strange error on my hosts when I log in showing...

I am seeing the following error every minute or so in my vdsm.log as follows....

2019-07-09 12:50:31,543+0200 WARN (qgapoller/2) [virt.periodic.VmDispatcher] could not run <function <lambda> at 0x7f52b01b85f0> on ['9a6561b8-5702-43dc-9e92-1dc5dfed4eef'] (periodic:323)

Then also under /var/log/messages..

Jul 9 12:57:48 host-a ovs-vsctl: ovs|00001|db_ctl_base|ERR|unix:/var/run/openvswitch/db.sock: database connection failed (No such file or directory)

I'm not using ovn so I'm guessing this can be ignored.

If I search for ERROR or WARN in my logs nothing relevant is logged

Any suggestions on what to start looking for please?

Please let me know if you need further info.

Thank you.

Regards.
