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

VCPU:           1

Of course, the HV works fine.
# virsh vcpupin 25 0 0

# virsh vcpuinfo 25
VCPU:           0

CPU Affinity:   yy

VCPU:           2
CPU:            1
