Shutdown a hung VM on XenServer

Option 1:

The first thing to try is a force shutdown on the VM:

xe vm-shutdown -–force uuid=[UUID for VM]

If this still doesn’t work you can try taking a look in the XenServer pending task queue:

xe task-listxe task-cancel uuid=[task uuid]

---

Option 2:

1. get server’s UUID from xencenter
2. Run the following command:
   list_domains | grep 6915704e-e6c1-9310-3405-0fcda6fded5e
3. Run the following command (replacing the “49” with the domain you received from running the command in step 2):
   /opt/xensource/debug/xenops destroy_domain -domid 49

---

Option 3:

1. run this: list_domains | grep 6b808153-55ac-5c5b-b778-d596dad8d1a2
2. run this: /opt/xensource/debug/xenops destroy_domain -domid 162
3. do an xe-toolstack-restart on the host it was running on
   after that, the server will probably say “vdi unavailable”…
4. follow these instructions: http://blogs.citrix.com/2011/11/08/vdi-not-found-when-starting-a-vm-on-xenserver-5-6-sp2/
5. run this: xe vm-start vm=DMZwiki
6. run this: xe vdi-forget uuid=bde9274e-864b-4822-96a7-cd2ed76165f0
7. run this: xe vdi-param-set uuid=bde9274e-864b-4822-96a7-cd2ed76165f0 name-label=DMZwiki_old
