VM will not migrate - "Could not fetch data needed for VM migrate operation"

[WildStar2022]

"Could not fetch data needed for VM migrate operation"

• oVirt Engine Version 4.5.5-1.el8 **

Describe the bug

Unable to migrate any individual VMs, including Hosted-Engine. Receiving the error "Could not fetch data needed for VM migrate operation".

To reproduce

In an NFS environment with two Hosts and with Hosted-Engine, we are unable to migrate any VMs... individually, including the Hosted-Engine.

However, when one Host is placed in maintenance mode, all VMs do migrate successfully to the other available Host.

Additional comments

• Same issue whether trying to migrate VM from Host 1 to Host 2 or Host 2 to Host 1.
• No events recorded in the administration portal Events, or in engine.log during the failed VM migration.
• A search reveals that this bug "may" have apparently been fixed in 2019 per RedHat Bugzilla 1670701, and duplicate 1690862.

Additional context

[WildStar2022]

Forced an update (4.5.7) yesterday afternoon and rebooted. Still could not migrate a single VM.

Just for shits and giggles, attempted to migrate a VM this morning and it worked! The migrate button is my new friend! It works every time! Wish I knew what changed though!
