Hi, HW: Compaq evo laptop, 640Mb ram, 800MHz cpu Xen: 3.0.3 on Ubuntu Edgy (2.6.17-6-generic-xen0) Problem: I have created 4 DomU''s. When I start the third DomU a Kernel panic appears, and after some seconds the computer shuts down. I don''t know where to get this output, and th messages on screes only stay for some seconds. The only thing I can see is this ''Kernel panic'' message. This occurs when starting equally which 3rd DomU. Please help. Laptop is normally stable when using a ''normal'' kernel.

Seems to be the same problem, I had posted before ("crashing with second
guest.")
Would like to know, if it''s the same hardware- arrangement (AMD K7 CPU)
and/or kernel (2.6.17-xen-k7).
I removed Xen and reinstalled by also changing the kernel to
2.6.18-xen-k7, and now problems seem to be solved.
But also don''t found any logentry on this crashing-behaviour.

How did you upgrade to 2.6.18-xen-k7? From source or by changing /etc/apt/sources.list? thanks, // Randy _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

From source > or by changing /etc/apt/sources.list?I inserted an entry in the sources.list for sid or unstable. Today I found a newer version of the 2.6.18: -2-xen-k7. Was pretty simple. But had also cases, when xend refused to start. Lasted installation with just the debian very base-system added by the xen-2.6.28-system worked out of the box.

I have setup xen 3.03 on a Athlon X2 3600 box, with 3 vertual machine, one acts as a firewall, and two act as tomcat server. When the load gos high, xen 3.03 kernel panic.The kernel is slef-compiled on ubuntu 6.10. What can I do to collect useful information to locate and solve the problem? Thanks! Best rgards.
