Sometimes you run into a hung VM on XenServer. This is how to kill the VM running on XenServer :
First look up the UUID (in my case 50fa073a- etc)
Using the command list_domains you can find the id’s (0, 6, 7, 9 etc)
Now use the grep command to find the domain ID you need and use the following command to kill the VM : /opt/xensource/debug/xenops destroy_domain –domid <domainid>
