Re: [Xen-users] Xen system hang or freeze

Another crash after two weeks.

I couldn't connect via serial this time (The hypervisor is in another office and I needed to start it quickly )

This time I've found errors inside a domU:

Are you running the Debian 2.6.18 kernel, or xenlinux 2.6.18.8 ?

xenlinux 2.6.18.8

I'll connect the serial in the next hang and show the errors

Thanks!

Are you running the Debian 2.6.18 kernel, or xenlinux 2.6.18.8 ?

You should set up a serial console to get the error messages and/or

It's pretty hard to debug it otherwise.
