- dom0: Linux kernel 2.6.18
- domU:
- Windows 2008, 64 bit installation ,4 cores, + 20GB memory
- Windows XP, 32 bit, 2 cores, 2GB memory.
- Debian lenny: 64 bit, 3 cores, 8GB

Hi,
my Xen server basically runs stable with lots of Linux domU's. This changes as soon as I start a domU running Windows 2008 Server: Sometimes it takes only minutes, sometimes it takes days until the whole server either freezes or reboots — usually without any message on console or logs. Sometimes I've got messages like "rejecting I/O to offline device" on console that lead me to a reported bug in the megasas driver. So I updated it to 4.01.
Since then I have never seen the "rejecting I/O..." messages again but the system still freezes or reboots shortly after creating the W2k8 HVM domU. I have already setup syslog forwarding to a another server but there are no helpful messages either.
Software details:
- Xen 3.3.1 (Debian 5.0/Lenny), 64 bit
- dom0: Linux kernel 2.6.26-2-xen-amd64
- domU: Windows 2008, 64 bit installation + James Harper's GPL PV drivers, 4 cores, 4096 megabytes memory
Hardware configuration:
- 2x Intel Xeon 5140 (dual core)
- Intel SRCSAS18E RAID controller using the megasas driver
Any ideas?
Kind regards,
Stephan
