[ovirt-users] Re: Host non-responsive after yum update CentOS7/Ovirt3.6

I assumed that if ovirt3.6 required older versions of CentOS7, etc, it would not allow the yum update due to dependency.  I guess that's a bad assumption. vdsm does not start in fact.  Here's the journal when attempting to start it. # journalctl -xe Jan 19 10:13:36 vmserver2 vdsm-tool[6794]: libvirt.libvirtError: authentication failed: authentication failed Jan 19 10:13:36 vmserver2 vdsm-tool[6794]: Traceback (most recent call last): Jan 19 10:13:36 vmserver2 vdsm-tool[6794]: File "/usr/bin/vdsm-tool", line 219, in main Jan 19 10:13:36 vmserver2 vdsm-tool[6794]: return tool_command[cmd]["command"](*args) Jan 19 10:13:36 vmserver2 vdsm-tool[6794]: File "/usr/lib/python2.7/site-packages/vdsm/tool/restore_nets.py", line 41, in restore_command Jan 19 10:13:36 vmserver2 vdsm-tool[6794]: exec_restore(cmd) Jan 19 10:13:36 vmserver2 vdsm-tool[6794]: File "/usr/lib/python2.7/site-packages/vdsm/tool/restore_nets.py", line 54, in exec_restore Jan 19 10:13:36 vmserver2 vdsm-tool[6794]: raise EnvironmentError('Failed to restore the persisted networks') Jan 19 10:13:36 vmserver2 vdsm-tool[6794]: EnvironmentError: Failed to restore the persisted networks Jan 19 10:13:36 vmserver2 systemd[1]: vdsm-network.service: main process exited, code=exited, status=1/FAILURE Jan 19 10:13:36 vmserver2 systemd[1]: Failed to start Virtual Desktop Server Manager network restoration. -- Subject: Unit vdsm-network.service has failed -- Defined-By: systemd -- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel -- -- Unit vdsm-network.service has failed. -- -- The result is failed.
