​Is ovirt-guest-agent installed on all pool's VMs? Consider installing
ovirt-guest-agent
in all VMs in your Pool to decrease the time taken for the VM shutdown.

-          Is it possible for normal users to use “power off”?

​There is no option in UserPortal to power-off a VM but you can
​try to click twice (sequential clicks) on the 'shutdown' button. Two
sequential shutdown requests are handled in oVirt as "power off".

​You can consider assigning two VMs per each user, if possible of-course
(via WebAdmin->edit Pool -> and set "Maximum number of VMs per user" field
to "2") so that way while one VM is still shutting down, the user can
switch and connect to a second VM without waiting.

Another option is to create a pool with a different policy for console
disconnecting so that the VM won't shutdown each time the user close the
console (via WebAdmin->Pool->Console tab->"Console Disconnect Action").
Consider changing this field to "Lock screen" or "Logout user" instead of
"shutdown virtual machine".
This policy will avoid accidentally console disconnection waiting each
time...but on the other hand the VM state will remain as is since no
shutdown occurs, so it really depends on your requirements.
