[ovirt-users] Problem: My VM's keep logging off

[Pedro ML Sousa]

My VM's keep logging off

I have a HP server with 64GB of ram and 2 TB of disk space, the cpu is a 
Intel E5-2420v2 and 13 thin clients from igel 
(https://www.igel.com/products/thin-client-zero-client-hardware/iz2ud2-series/iz2ud2-specifications.html)
i've purchase the clients and a service from a company, they installed 
the thins clients and the system but they are not finding a solution to 
my problem.
The company installed centos 6.6 (final) (kernel linux 
23.32-504.3.3.el6.x86_64) and ovirt 3.5.1 for virtualization 
(o.o.master.20141206225404)
I have 12 VM's with centos (when i edit then is shows red hat enterprise 
linux 6.x x64) and gnome desktop 2.28.2 and 1 VM with windows xp prof.

The problem only occurs on the VM's with linux.

On linux display type is: Spice I use virtual machine viewer 1.0256

*Problem: when working the vm seems to log off and i have to put the 
username and password again, all the work that was open is losed.*

1 VM seems to log off more or less at the same hour each day 1h40 pm and 
6h15 pm. This VM now as a newer thin client version UD3 instead of UD2 
(https://www.igel.com/products/thin-client-zero-client-hardware/iz3ud3-series/iz3ud3-specifications.html) 
and now the problem only occur 1 time each day (at 12h30/12h45pm).

All of the VM's including the one with XP Pro suffers from slowness, and 
on libreoffice the mouse scrooll seems nuts scrolling up and down by 
itself, now the exception is the VM with the new thin client.

On the same network switch i have VM's that logs off and others that 
remain on. So the problem doesn't seem to be with the network. The 
different VM's logs off from 1 to 7 times a day. Mostly 4 to 5 times a day.

When the VM logs off the caps lock become to work on the opposite 
condition off with caps light on and on with the caps light off.

Beside this i have problems with the canon's printes i have, they stop 
printing quite often.

I have access to the logs if anyone can help me i can upload the logs 
you like.

Hope anyone can help me, i'm glad to provide more information if you need.

Thanks in advance.
