Is it possible to know what techniques xen developers use? I see that there is some printk messages that can be recover using a serial line. I also see a file containing the "Xen pervasive debugger" which can display informations if DEBUG_TRACE is set. Is there others mechanism or secret keys?

On the serial console type ''h'' and it gives you a list of debug outputs available, such as dumping the list and state of vms, a bunch of performance counters etc. I think you can also uses these on the console. See an earlier message from Bin Ren about the key combination. Otherwise, I normally use printks for debugging. We are also working on a simple trace buffer which will allow you to get a history of events.

The pervasive debugger is work in progress. Its target is debugging domains and client applications rather than Xen itself.
