[Xen-devel] How to dump xen0 kernel output to a serial console?

["Lily Huang" <ushuanglily@xxxxxxxxx>]

Hello,

I am running into xen0 crash. Every time xen0 crashes, it will dump some error messages. Unfortunately, before I can read the details, the system already restarted. Is there anyway to dump the error message to a different serial console? 

How to debug xen0? I mean, xen0, not xen itself. 

Please give me some ideas or direct me to the right place to read the documentation.

Many thanks!
