Hello,
my xen server runs basically fine since today. But now i get a kernel
panics during startup dom0 or domU. I did not update the system the
last days, so it could be an hardware issue.
System:
Asus P5e-vm do
Intel Q6600
8 GB Ram
4x SATA (md raid 10)
Debian Lenny
Kernel: 2.6.26-xen-amd64
xen 3.4.1
domu:
2x Windows HVM (1 with device pass-through)
2x PV Linux
Sometimes, dom0 freezes when i restart or stop a domU.
The attachment is cutout of the syslog. When you need more information,
please let me know.
Thanks,
Stefan
