I have just completed a clean install of FC7 test 4 on a custom built machine: MB: Gigabyte GA-965P-DQ6 CPU: Intel Core 2 Duo E6600 Video: Asus EN7900GS RAM: Veritech DDR2 800 1 Gig x 2 HD: Pair of Maxtor 120 Gig SATA drives running as a mirrored RAID array through the hardware controller on the motherboard The install ran fine, but when I boot the Fedora xen kernel (2.6.20-2925.5.fc7xen) it crashes during the boot process. If I boot "Fedora base (2.6.20-1.3104.fc7)", then it boots fine. When booting the Fedora xen kernel the last output in the console is: Kernel panic: Not syncing - Aiee, killing interupt handler! I have seen a thread in this list talking about problems with the 2.6.20-2925.5.fc7xen kernel. Can anyone suggest what I may be able to do to work around this problem? Is there a different xen kernel that I could be using with FC7? If so, where would I get it from? I am new to virtualisation and average with Linux, so would greatly appreciate any assistance.

If so, where would I get it from?You don''t mention what architecture you''re installing ? i686 or x86_64 ? We just built a new kernel into rawhide which 2.6.20-2925.7.fc7xen which fixes a bunch of things, including checksum corruption in networking and SMP support in 64-bit. This still has a major outstanding problem which affects many 32-bit machines though - debugging is ongoing & trying to get it resolved before F7 GA. So anyway, if you''re using the 32-bit kernel I imagine you''ve hit the known panic problems we''re investigating.

If anyone is running rawhide with Xen and seeing crashes/hangs/wierd behaviour, please give the 2.6.20-2925.8.fc7 kernel a try. Its not in rawhide YUM repos yet, but you can it from Koji http://koji.fedoraproject.org/packages/kernel-xen-2.6/2.6.20/2925.8.fc7/ NB. this requires xen-3.1.0-0.rc7.1.fc7 userspace.

I''ve seen a number of bugzillas with a similar complaint to you, that only a (random) fraction of guests successfully start upon boot. My best guess is that the high load causing by starting lots of guests at boot causing timeouts when setting up backend devices & thus crashes the guest. Not had any time to investigate it seriously, or even see if this guess is correct.

Hello, I think Dan is right as I had the same kind of problem earlier. I fixed this issue by following a Dan''s advice on another bug involving performance issue. You can find the fix in a previous message on this list: http://www.redhat.com/archives/fedora-xen/2007-April/msg00166.html The key is to mount /var/lib/xenstored in shared memory to limit som I/O overhead.
