Yes, Live dump feature is also useful.
My "xm dump" is "xm crash" as Tristan said.
I think it is better that we make both live dump and panic dump option.

How about the below?

e.g.
In the case of live dump
  xm dump -l domU
  
  For example, live dump option is used when domU kernel is santy 
  and applications are not sanity.
  
In the case of panic dump 
  xm dump domU or
  xm dump -p domU ( -p is default)
  
  For example panic dump option is used when domU kernel is hungup,
  and we want to reboot and make coredump atomatically.
  
Best Regards,

Akio Takebe
