Hi Isaku,

Thanks for your patch. 

I was encountering xm dump-core command error with latest xen-unstable. 
The command error was as follows. 

 # xm list
 Name                                        ID   Mem VCPUs      State   Time(s)
 Domain-0                                     0   747     2     r-----     63.2
 vm1                                          1   256     1     r-----    111.1
 # xm dump-core vm1
 Dumping core of domain: vm1 ...
 Error: Failed to dump core: (1, 'Internal error', 'No VCPU context could be 
grabbed (14 = Bad address)')
 Usage: xm dump-core [-L|--live] [-C|--crash] <Domain> [Filename]
 
 Dump core for a specific domain.
   -L, --live                     Dump core without pausing the domain
   -C, --crash                    Crash domain after dumping core


But, the command error was resolved by your patch. 

Best regards,
 Kan
