Re: [ovirt-users] vm shutdown long delay is a problem for users of pools

Hi Sharon, Thanks for your comments. My findings on those: 1. Yes all VMs have ovirt-guest-agent installed and active, shutdown time is still about 90 seconds. Any other way to reduce this? I see in the logs “Jun 28 11:49:03 pool python: Shutdown scheduled for Wed 2017-06-28 11:50:03 CEST, use 'shutdown -c' to cancel.” And then a wait of 60 seconds. Is it possible to adjust this delay?

2. Clicking twice works. Thanks for the tip! 3. a. More VMs per user: yes, could be a good option b. I have some trouble with the “console disconnect action” and filed a bug for it last week [1]. Any disconnect action (except shutdown) combined with “strict user checking” (security wise recommended) blocks and depletes pool resources and in my opinion jeopardizes the pool functionality. I am curious what your thoughts are on this.

I read this is mainly due to a 60 second delay in the ovirt-guest-agent. I got used to right-click and use “power off” instead of “shutdown”, which is fine. My users make use of VM in a VM-pool. They get assigned a VM and after console disconnect the VM shuts down (default recommended behavior). My issue is that the users stays assigned to this VM for the full 90 seconds and cannot do “power off”. Suppose he disconnected by accident, he has to wait 90 seconds until he is assigned to the pool again until he can connect to another VM. My questions are: - Is it possible to decrease the time delay of a VM shutdown? 90 seconds is quite a lot, 10 seconds should be enough ​​ ​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". - Is it possible to “unallocate” the user from a VM if it is powering down? So he can allocate another VM ​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.
