It would be nice to have an option in oVirt to reset (libvirt reset) a VM. The only way now to restart a hanging VM is doing a Power Off and start. But this takes more time, shuts off the console, etc. While a reset is quick, you can keep the console open etc. And I guess its not that hard to implement :) It was already requested in #1136819 years ago, but seems like that has been closed as duplicate of some irrelevant bug.

Verified with: ovirt-engine-4.4.6.3-0.8.el8ev.noarch vdsm-4.40.60.3-1.el8ev.x86_64 libvirt-7.0.0-13.module+el8.4.0+10604+5608c2b4.x86_64 Steps: 1. Create and run a VM(used latest-rhel-guest-image-8.3-infra template) 2. Open VM console 3. Reset VM on UI 4. Reset VM via API POST /ovirt-engine/api/vms/22c3cc4b-921e-42b2-ac3b-17426100dfc4/reset <action> <async>true</async> </action> 5. Update a VM parameter which requires VM restart, such as enabling Smartcard, then reset the VM Results: 1. On UI, Reset button is in the dropdown list of Reboot, Resetting VM via Reset button succeeds, VM console remains connected. 2. Resetting VM via API succeeds, VM console remains connected. 3. Smartcard is enabled after VM is reset.
