Hello, I am having problems at getting Xen to boot. I''ve been trying really hard since last friday and I can''t seem to get it to run. I''ve gone through all sorts of problems, I only got it to work once and even when I was able boot dom1, it didn''t work fine! several crashes in between (like freeze, no kernel panics or any other sort of printk()ed messages before crash) as such I beg your attention and patience :-) I was given a DELL PowerEdge 2850 to setup with 4 virtual machines, all of them running linux. I''ve downloaded xen 3.0.0 stable source, unstable source, scripts to automate and the rpm versions, the only time I was able to make it go a little longer. Specs: ::PowerEdge 2850 3 SCSI disks at 10K/146gb configured in raid 5. 2 cpu Intel P4 xeon 3.0 (plus with hyperthreading) 8GB ram:: I''ve RHEL Advanced Server 4.0 installed.

The symptoms are, everything goes well until the first rc scripts are executed, I can see it starting ''udev'' and something else that starts after udev, but then there''s a panic and BAM automatic reboot! Wish I could "freeze" it to know what happen. Is there something I can do to understand what''s going on here? I felt tempted to install kdbg patches to have it popping up whenever a crash occurred but I remember that xen simulates a new architecture and so the patch may not go into the right files as I wanted. Any piece of advice will be godsent! Thank you very much!

If that doesn''t work, try ''nousb''. Please report back to the list.

I had been trying to install xen on a DELL PowerEdge SC430 with no success. Infact the xen live demo CD (3.0) was not booting up on these machines. I am not sure if others were successful in booting into a dual core systems, but I am presuming this could be a problem with the dual core systems. Suggest using the xen live cd to check if a system is compatible. Gautam --- Hello, I am having problems at getting Xen to boot.

I retried it on the poweredge sc430 server. The live cd works fine till loading gdm. Once that happens, the monitor goes into a sleep-mode and the system does not respond. Any ideas on this would be greatly appreciated.

I have not had any problem with Dell boxes once this is done, and lots of hangs if it is not set. Hope this helps. -- -Barry Flanagan _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

This will cause the linux to boot into run level 3 (rather than 5) which does not start an Xserver. You can then edit the /etc/X11/xorg.conf before starting the server with "gdm start". You may find that replacing the ''Driver "vesa"'' directive with the name of the driver needed for you card may be sufficient e.g. ''Driver "i810"''. Alternateively, run "X -configure" and copy the directives from the resulting config file.

Thanks Ian. I was able to boot into run level 3. I changed the driver to the one detected by X. However, after the change, the system still hangs. Barry, "nousb" option on the kernel boot options did not help either.

What happens if you run "X -configure"? Ian _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
When I ran ''X -configure'', it created the configuration for X with a driver kbd. I had used that information for configuration.
