[ovirt-users] VDSM will not start

[Jonas Kirk Pedersen]

Had a problem where on the host the vdsm service would not start. The 
following is from #ovirt IRC chat after I emailed the sos report from 
the host

13:29:06) sbonazzo: jkp looks like an issue while starting supervdsm, I 
see:
(13:29:08) sbonazzo: Mar 9 12:41:30 kvm1 daemonAdapter: OSError: [Errno 
2] No such file or directory: '/var/run/vdsm/svdsm.sock'
(13:29:08) sbonazzo: Mar 9 12:41:30 kvm1 systemd: start request repeated 
too quickly for supervdsmd.service
(13:29:26) sbonazzo: danken: ybronhei: nsoffer ^^
(13:30:57) sbonazzo: msivak: i see also Mar 9 12:27:18 kvm1 systemd: 
[/usr/lib/systemd/system/momd.service:11] Unknown lvalue 'Timeout' in 
section 'Service'
(13:31:30) sbonazzo: msivak: maybe epel7 mom should be updated
(13:32:33) sbonazzo: after that, vdsm doesn't come up due to Mar 9 
12:27:55 kvm1 daemonAdapter: OSError: [Errno 2] No such file or 
directory: '/var/run/vdsm/svdsm.sock since supervdsmd didn't run
(13:34:50) sbonazzo: jkp: can you try to manually start supervdsmd service?
(13:35:07) jkp: sbonazzo, it is confirmed that the file is not there. 
But shouldn't the service create this file -- Yes I'll try
(13:35:19) sbonazzo: jkp: yes, it's supposed to
(13:39:07) jkp: sbonazzo, still gives me the : OSError: [Errno 2] No 
such file or directory: '/var/run/vdsm/svdsm.sock'
(13:39:35) sbonazzo: jkp does /var/run/vdsm/ exist?
(13:40:55) jkp: sbonazzo, yes it contains [root at kvm1 ~]# ls 
/var/run/vdsm/ lvm sourceRoutes trackedInterfaces v2v

Later I received a email

Mar  9 10:41:21 kvm1 journal: Module /usr/lib64/libvirt/connection-driver/libvirt_driver_lxc.so not accessible
Mar  9 10:41:21 kvm1 journal: The server certificate /etc/pki/vdsm/certs/vdsmcert.pem is not yet active

Mar  9 10:41:21 kvm1 systemd-logind: Removed session 4.
Mar  9 10:41:21 kvm1 systemd: libvirtd.service holdoff time over, scheduling restart.

I see that libvirtd fails to start.
It might be due to Engine system clock being deep in the future?

What I had failed to notice was that the vdsmcert.pem that was not active.
The ntp service running on the Engine was out of sync with a year 
resulting in that of cause the certificate did not work and then the 
vdsm would not start.
I have a fairly new engine so I removed it and fixed the time issue and 
all was perfect

Thanks for a great help on the chat and on email
