Windows Server 2003 guest on Xen frequently stops responding
- by smokris
I'm running a Windows Server 2003 guest instance in Xen 3.x. This DomU runs fine for a day or two, then stops responding — I don't get any network response, and I can no longer connect to Xen's VNC console for this DomU.
xm list shows this:
Name ID Mem VCPUs State Time(s)
Domain-0 0 6508 8 r----- 1161159.4
[A working Linux DomU] 1 512 1 -b---- 68711.1
[The hung Windows DomU] 5 512 1 ------ 67234.2
[Another working Linux DomU] 3 512 1 -b---- 163036.4
(What does the ------ mean? The xm manual explains what each of the six states mean, but not what no-state means.)
If I xm destroy and then xm create the Windows DomU again, it boots right back up (with the Windows alert The previous system shutdown at [...] was unexpected.), and then stops responding after another day or two.
I checked /var/log/xen/*.log, but no log messages are generated at the time the server stops responding.
How should I proceed in troubleshooting this?
