[ovirt-users] remote-viewer + squid / console hangs (tcp timeout/keepalive?)

[Derek Atkins]

Hi,

I've got a squid proxy set up for my ovirt console, which works great. 
However, if I'm connected to a (non-graphic) console and step away for
several minutes (somewhere between 15-30 -- I haven't figured out exactly
how long), the console will freeze.  My TCP connections still seem to be
active (they don't disconnect) -- I still see the connection between my
remote-console and squid, and between the squid and console host.  However
if I type into the console I see nothing.

Has anyone seen this issue and know how to correct it?

This is with ovirt 4.0.5 on centos 7.2.  The guest doesn't seem to matter
-- I've seen this issue with different guests.

Thanks,

-derek

Hi Chris,

Just a quick question, but, why not just use ovirt-shell?
Or make this a wrapper around ovirt-shell?

One reason for reboot is loosing access to storage on the spm host. sanlock
would terminate vdsm, and if it could not terminate vdsm it will
reboot the host.

To check for this you can look into /var/log/sanlock.log

Another reason may be engine trying to do soft-fencing because it cannot
restart vdsm. Looking in vdsm log you can find if vdsm was restarted, and
in engine log you should find logs about this.

Are you sure you don't have any cron job or some other code that is
configured reboot the host?

[ovirt-users] Spurious reboot?

[Derek Atkins]

Hi,
Last night at approximately 22:03 (give or take a few minutes) my single-server 
ovirt system rebooted.  I saw a root login (presumably from the engine) and 
then the host rebooted.

I don't see anything specific in the logs that would indicate WHY it rebooted.

Any suggestions for where to look or what to look for?  I had updated the host 
yesterday to 4.0.5 and did reboot the system myself several times.  The good 
news is that I succeeded in getting my scripts working so all my VMs came back. 
 But before I go and deploy anything mission critical I'd like to determine why 
the system decided it should reboot.

Suggestions?
