Re: [Xen-users] Debugging (possible) Xen-related hang-issues without the possibility of attaching serial console to capture Xen output

Two thoughts:

1. Have you thought of installing an IPMI card into your box (if available), or hooking up a serial-over-IP box like this one - http://www.lantronix.com/device-networking/external-device-servers/eds1100_eds2100.html - I've found remote access to a serial port to be invaluable.

2. I used to have a really bad crash/hang/reboot issue with my xen installation. It turned out that the solution was to pin VMs to CPUs - otherwise there was an intermittent scheduling conflict that would simply come up once in a while and crash things. Never could actually find trace of it in logs, but pinning CPUs eliminated the issue. Not sure if that problem has been solved in later releases.
