[Libvir] virsh vcpupin does not work with xend
Hi, The virsh vcpupin command does not work when it uses Xend(xend_internal.c). HV(xen_internal.c) works fine. I'm testing on Xen3.1.0(hypervisor_version=2, dom_interface_version=5, xendConfigVersion=4), and using current libvirt(ChangeLog revision 1.546). To solve this problem, I got the xend debug information and compared that. * in the case of executing "virsh vcpupin 63 7 1" * [2007-05-29 09:33:20 4258] DEBUG (XendDomain:1297) dom(63) cpu 7 cpumap [1](<type'str'>) * in the case of executing "xm vcpu-pin 63 7 1" * [2007-05-29 09:33:32 4258] DEBUG (XendDomain:1297) dom(63) cpu 7 cpumap [1](<type'list'>) There is one different thing. The type of cpumap is str when executing virsh command, but the type of cpumap is list when executing xm command. Do you have any idea ? Thanks, Saori Fukuta

Did you find out what caused this in the end?

I have no progress about this. I suspect that the cause is the type of cpumap, and I want to try to send the cpumap as list but I have no idea the way. So I can still not determine the reason. Saori.

I'm not sure how to reproduce this. How can I send the map over xend instead of the HV? I did fix a problem with virDomainPinVcpu & remote about two weeks ago.

It is rare case. This problem is occurred when the HV is failed. So, to reproduce this, I changed the domainPinVcpu of HV to NULL. --- 625 #if 0 626 xenHypervisorPinVcpu, /* domainPinVcpu */ 627 #else 628 NULL, 629 #endif and executed it. # ./virsh vcpupin 25 0 0 # virsh vcpuinfo 25 VCPU: 0 CPU: 1 State: blocked CPU time: 261,1s CPU Affinity: yy <--- VCPU: 1 CPU: 1 State: blocked CPU time: 240,0s CPU Affinity: yy VCPU: 2 CPU: 1 State: blocked CPU time: 245,2s CPU Affinity: yy Of course, the HV works fine. # virsh vcpupin 25 0 0 # virsh vcpuinfo 25 VCPU: 0 CPU: 0 State: blocked CPU time: 261,2s CPU Affinity: y- <--- VCPU: 1 CPU: 0 State: blocked CPU time: 240,0s CPU Affinity: yy VCPU: 2 CPU: 1 State: blocked CPU time: 245,2s CPU Affinity: yy Thanks, Saori
