Please specify the compute type you are using (oVirt, Libvirt) ?

i use libvirt

The power off button with libvirt is sending an ACPI call to power off.
This is not a force shutdown. Maybe when you tried to shutdown your host,
your environement didn't support the ACPI call ?

How can i check this?

what version of libvirt are you running?
What kind of guest are you shutting down (OS and version)?
What hypervisor are you using (type and version)?

what version of libvirt are you running?

libvirt-0.9.4-23.el6_2.8.x86_64

What kind of guest are you shutting down (OS and version)?

ScientificLinux 6.2

What hypervisor are you using (type and version)?

does this mean we should default to force shutdown? offer two options etc?

I think that we should offer two button (like virt-manager offers 'Shut Down' and 'Force Off').
Force off as default behavior is really not a good idea IMHO.

I think it makes sense to offer two options.

Was a bit surprised that "Power Off" wasn't working and was trying to figure out why an libvirt VM didn't power off (it was not done provisioning so did not have acpi in OS).

Maybe could be nice to offer few options from the host view page - S5 (I think?) power off, Pause (suspend), Resume, Ctrl-alt-delete? Perhaps make the same click icon there is now also serve as a hover drop-down. Jeje, I shouldn't say too much - I'm no UI guy.
