[Xen-devel] [PATCH] Fix xm vcpu-pin for Domain-0

[Masaki Kanno <kanno.masaki@xxxxxxxxxxxxxx>]

Hi,

A bogus error message is shown with the latest xen-unstable when 
using xm vcpu-pin command to Domain-0 and guest domains.  I send 
a patch solving the issue.

 # xm vcpu-pin Domain-0 0 0
 Error: Cannot pin vcpu: 0 to cpu: [0] - list assignment index out of range
 Usage: xm vcpu-pin <Domain> <VCPU|all> <CPUs|all>
 
 Set which CPUs a VCPU can use.
 # xm vcpu-list Domain-0
