Description Will Nguyen 2008-09-29 15:36:01 EDT
Description of problem:
If a VM is running when xend is restarted, and the VM is then shutdown, the VM will go to Zombie state.

Version-Release number of selected component (if applicable):
- Red Hat Enterprise Linux Server release 5.2 (Tikanga)
- 2.6.18-92.el5xen

How reproducible:

Steps to Reproduce:
1. Install a new RH5.2 (64-bit) host with Xen
2. Use virt-manager to create a new VM
3. Start the VM from virt-manager
4. Run "/sbin/service xend restart"
5. Shutdown the VM from virt-manager

Actual results:
The virt-manager GUI will display the VM constantly switching between the on and off state. The "virsh list" command will show the VM in Zombie state.

Expected results:
The VM should shutdown successfully without entering into a Zombie state.

Hello Will,

I need more information as I was not able to reproduce this bug. What is the type of virtual machine you are creating? Is it a fully virtualized machine or a paravirtualized one? What operating system is running inside the VM?

Could you, please, also share exact version number of xen package?

In addition, VM's configuration file (/etc/xen/VM_name) and messages written to /var/log/xen/xend.log and /var/log/xen/xend-debug.log after you tell virt-manager to shutdown the VM would be really helpful. Please, send these as attachments to this bug.

Hi Jiri,

Here are the information you need, I do this on behalf of Will.

Type of VM: Fully virtualized machine

Guest OS: Red Hat Enterprise Linux AS release 4 (Nahant Update 6) 64bits

Version number of Xen package:
$ rpm -qa | grep xen 

Output of "virsh list" when this problem occurs:
$ virsh list
 Id Name                 State
  0 Domain-0             running
  2 Zombie-rhel46_full_virt64 no state

I have checked there are no any messages written to /var/log/xen/xend-debug.log when this problem occurs, I will attach VM's configuration file and /var/log/xen/xend.log later.

In the attached Xend.log, you see I started a VM at 20:33:20, restarted Xend service at 20:36:02, and shutdown the VM at 20:37:57, then this problem occured.
