Hi,
I'm using libvirt/kvm with openstack. When vm has CPU stall, the instance
can't be destroyed. I have asked the question on openstack user mailing
list and received no answers in weeks.
Here is one example:
# virsh destroy instance-00000085
error: Failed to destroy domain instance-00000085
error: Failed to terminate process 61222 with SIGKILL: Device or
resource busy
# lsof -p 61222
# ps -f -p 61222
UID PID PPID C STIME TTY TIME CMD
107 61222 1 68 Jan24 ? 9-23:06:19 [qemu-system-x86]
<defunct>
The log in /var/log/libvirt/libvirtd.log:
2014-02-08 03:21:31.597+0000: 2177: error : virProcessKillPainfully:315
: Failed to terminate process 61222 with SIGKILL: Device or resource busy
Restart libvirt-bin service did not solve the problem.
virsh shutdown/reboot just hang. Maybe that is because the CPU in vm is
stalled.
I wonder if there is some way to destroy (or rebuild) dead instance without
rebooting the hypervisor. Any suggestions is welcome.
The software I am running:
hypervisor os: ubuntu 12.04.3
hypervisor kernel: 3.8.0-35-generic
vm os: ubuntu 12.04
vm kernel: 3.2.0-56-virtual
openstack: havana
libvirt: 1.1.1-0ubuntu8~cloud2
Thanks,
Yuanle
