Hi, 

I could not get xm dump-core with the latest unstable(#14679).
Have anyone hit the same issue?

The below is the xend.log.

[2007-04-03 16:20:02 4783] INFO (XendDomain:1152) Domain core dump requested
for domain vti (1) live=0 crash=0.
[2007-04-03 16:20:02 4783] ERROR (XendDomainInfo:1277) XendDomainInfo.dumpCore
failed: id = 1 name = vti
Traceback (most recent call last):
  File "//usr/lib/python/xen/xend/XendDomainInfo.py", line 1272, in dumpCore
    xc.domain_dumpcore(self.domid, corefile)
Error: (1, 'Internal error', 'No VCPU context could be grabbed (2 = No such
file or directory)')
[2007-04-03 16:20:02 4783] INFO (XendDomain:1105) Domain vti (1) unpaused.


This message is occured at the following code.
We cannot get xc_core_arch_context_get()?

 365     for ( i = 0; i <= info.max_vcpu_id; i++ )
 366     {
 367         if ( xc_vcpu_getcontext(xc_handle, domid, i, &ctxt[nr_vcpus]) == 0
)
 368         {
 369             if ( xc_core_arch_context_get(&arch_ctxt, &ctxt[nr_vcpus],
 370                                           xc_handle, domid) )
 371                 continue;
 372             nr_vcpus++;
 373         }
 374     }
 375     if ( nr_vcpus == 0 )
 376     {
 377         PERROR("No VCPU context could be grabbed");
 378         goto out;
 379     }
