destroy_domain is a very low level command, it talks to Xen hypervisor

Try restaringing xapi and destroy_domain.

Well this stinks, Started migrating VMs to get ready for the reboot, and
now all VMs are stck in "migrating" state - this cloud is my lifeblood
and now I'm going to have to reboot it forcefully because a VM hung,
which is a cardinal rule of Virtualization, don't hang DOM0.
Not blaming CS, but Xenserver blows. Citrix, this is your flagship
product and it will hang at the drop of a hat.
if it doesn't work, the only solution I know is to reboot the host,
you can migrate VMs to other hosts before you reboot this host.
Thanks for the tip. Is it not safe to assume the output of list_domains
is the hung VM in question?
117 | deadbeef-dead-beef-dead-beef00000075 | DS
looking up the code for DS d= dying, S=Shutting down. It's the only one
in that state in the list_domains output. Would killing domain 117
potentially crash DOM0?

Hi Nik,
List_domains and destroy_domain are working on host not pool.
So if you have multiple hosts in a XenServer pool , you might need to
execute above command on that host,
You can try following to find the host
Xe vm-param-list uuid="vm uuid" | grep resident-on
You will get the host uuid
Xe host-param-list uuid="above host uuid"
Then you get the host information.
Log into the host and retry the procedure to destroy VM.
I ran that command on the VM in question, and it hangs, on any host in
the pool. The command works fine for any other VM. This VM must be in
bad shape.

Anthony,
Running list_domains with the VMs UUID does not return any results,
but
if I just run list_domains, I get all the control domains, and one
odd
one:
117 | deadbeef-dead-beef-dead-beef00000075 | DS
could this be the control domain for the hung VM?

A bit more information, I logged in to Xen center and the VM is
hung
with a yellow arrow. There are no options to shutdown, reboot, or
anything. How do I force this VM off?

I

it's
hung in a migrating state. What is the best way to reset this VM

get back on track, and also diagnose why this happened?
