[libvirt-users] Failed to terminate process X with SIGKILL: Device or resource busy

FYI, I have found a way to terminate instance:
    virsh schedinfo <domain> --set vcpu_quota=20000
After this, shutdown, reboot and destroy all works. Of course, this
disables the vcpu throttling. It was set to 5000, which may cause the CPU
stall problem in guest.

Thanks,
Yuanle
