Greetings oVirt team

I'm using "Version 4.5.7-0.master.20240327074810.git14bca0502d.el8 on CentOS 
Stream 9"

I have occasion to restore a windows backup image for the purpose of data 
extraction. To accomplish this I need to boot off a Server 2008R2 ISO. The 
machine to be restored was UEFI based originally and so it is required to be 
UEFI for the restoration process.

I seem to be having a problem with booting off of the ISO image in the required 
UEFI-based system. In pursuit of a solution I've read on some of the other 
forums about this same problem on other KVM-based platforms.

Booting that same ISO after changing the VM to BIOS works flawlessly. In the 
articles and threads I've read there is mention of hyper-v services that load 
during the guest boot process that are causing the ISO boot to hang. 

Is it possible to disable (or is it even necessary to disable) 
"hv_time,hv_relaxed,hv_spinlocks=0x2000" in the "Custom Properties" section of 
the VM config ?

If any of you have some insight into this  problem and a possible solution I'd 
appreciate the feedback.
