You'll probably want to see if you can get SysRq output from dom0 via serial line. It's likely you can if it is alive enough to respond to ping. This might tell you things like what all processes are getting blocked on, and thus indicate what is stopping dom0 from making progress. -- Keir On 15/10/2010 13:43, "MaoXiaoyun" <tinnycloud@xxxxxxxxxxx> wrote: > > Hi Keir: > > First, I'd like to express my appreciation for the help your offered > before. > Well, recently we confront a rather nasty domain 0 no response > problem. > > We still have 12 HVMs almost continuously and concurrently reboot > test on a physical server. > A few hours later, the server looks like dead.
