Hi..
After an upgrade from 4.2.3 to 4.2.5 last week, I notice that I have a console + cockpit problem. Immediately following the upgrade, everything seemed to be working fine. However, today, a couple of days after the upgrade, when I try to view any CentOS VM console, virt-viewer starts, and I see "Connected to graphic server", but there's no console output. This happens on all Linux VMs, though on my two windows VMs, the console still works. If I restart a Linux VM, I get the console back again, but what made me lose access to all the consoles? In addition, if I right click on one of my 4 hosts, and choose "Host Console", it connects to cockpit which reports: "No VM is running or defined on this host" even though there are plenty. I brought one host into maintenance mode, and rebooted it. I then started a few VMs there, and cockpit still doesn't show anything running. All of the hosts have all available ovirt updates, and are running the latest CentOS 7 kernel + O/S updates. Any ideas? There is no issue with firewall.
One interesting point to add --- For one server running CentOS 6 and 2 servers running CentOS 7.4, I still had console. Any servers that had been upgraded to the latest kernel + CentOS 7.5 updates were the ones where console was not accessible. However, console *was* accessible on those servers at the time they were upgraded. Jason.
