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.
