hi
One VM is completely hanging since 15 min. with the message:
Power off Virtual Machine, Status 95%
We have ESX 3.5 Update2
Can I stop it form the command line?
Probably not, since the service is already in progress. Best course of action is power off the rest of the VM's, then reboot the server.
There isn't much you can do with a hung VM especially during power off. And update to 4.
any reason you can't update to ESX 4.0?
You can try logging into the host in question, run:
ps -efwww | grep -i vmname
get the PID from the line that starts /usr/lib/vmware/bin/vmkload_app and ends vmname.vmx and run:
kill -9 PID
