[Xen-bugs] [Bug 457] New: vcpu-set doesn't work on x86_64bit



http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=457

           Summary: vcpu-set doesn't work on x86_64bit
           Product: Xen
           Version: unstable
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Unspecified
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: pvanhoof@xxxxxxxxx


The command doesn't work on my x86_64bit setup. I've set the cpus and the vcpus
setting correctly in my configuration file (I have, for example, 4 cpu's. So
I've set it to 0-4 and 4). When I do vcpu-set to, for example, 3, xm list keeps
telling me the domain is using 4 vcpu's. /proc/cpuinfo on the xenU kernel tells
me the same thing.

[root@oceanus xen]# xm list
Name                              ID Mem(MiB) VCPUs State  Time(s)
Domain-0                           0     7060     4 r-----   432.1
pvanhoof                           8     1000     1 -b----     1.7
[root@oceanus xen]# xm vcpu-set pvanhoof 3
[root@oceanus xen]# xm list
Name                              ID Mem(MiB) VCPUs State  Time(s)
Domain-0                           0     7060     4 r-----   432.5
pvanhoof                           8     1000     1 -b----     1.7
[root@oceanus xen]# cat auto/pvanhoof.xen.cfg | grep cpu
cpus = "0-4"
vcpus = 0
[root@oceanus xen]#
