booting to,

    kernel /xen.gz ... dom0_vcpus=1 dom0_vcpus_pin sched=credit ...

i check,

 xm list
  Name                                        ID   Mem VCPUs
State   Time(s)
  Domain-0                                     0  1022     4     r-----     79.4

 xm vcpu-list Domain-0
  Name                                ID  VCPU   CPU State   Time(s)
CPU Affinity
  Domain-0                             0     0     0   -b-      37.4 0
  Domain-0                             0     1     1   -b-      13.0 1
  Domain-0                             0     2     2   r--      21.6 2
  Domain-0                             0     3     3   -b-      15.1 3

but,

 xm vcpu-set --help
  Usage: xm vcpu-set <Domain> <vCPUs>

  Set the number of active VCPUs for allowed for the domain.

then,

 xm vcpu-set Domain-0 1
 xm vcpu-list Domain-0

 (locks up the ssh session ... no response)

ssh in another session, try again,

 xm vcpu-list Domain-0

 (locks up the ssh session ... no response)


so, not sticking across boot ... and this odd lockup. thoughts?
