Xen users - Jun 2010 - lenny + xen reboots sometime

Hello,

 

I have a problem with debian lenny, xen-hypervisor-3.2-1-i386, 32bit Dom0
und 32bit Domu debian lenny on a IBM BladeCenter.

All is working fine and then sometimes the Blade reboots. When I add
noreboot in the menue.lst in Dom0 grub then the Server stops working and I
have to reboot manually. There are no error messages in the logs. The period
the server reboots is variable. Sometime it work 1-2 week and then it take
only on day to reboot.

The problem is on 8 blades the same, so I think it is no a hardware problem.

 

What shal I do?

Is it better to run 64bit Dom0 and 32bit DomU´s. Should I change from lenny
to squeeze, or sid? From debian to anything else?

Or is it possible to find out what is going wrong?

 

Thanks, Thomas

You can try. As others have posted on this list (search the archive),
64bit seems to be more stable on Lenny. Although James Harper noted
that PV drivers might not work for 32-on-64 since the necessary
support is added past Xen 3.2.

If you''re just looking for a stable production environment, I highly
recommend RHEL/Centos5.5.
