Install fails on KVM
I'm running into issues installing the utmfw 7.5 release on kvm. It seems like there's a panic when beginning to install the different sets. Attached is the definition for the virtual machine as well as a screenshot of the error message.

Guessing from the vm definition you didn't have any issues with v7.4, so this may be specific to v7.5. The first two error messages indicate a problem with the disk. Have you tried to recreate it and/or tried different disk options? I have never installed UTMFW on KVM (but I did install on VMware and Qemu many times), so I guess I won't be too much help, but if I can find time I can try myself who knows when.
Digging deeper I kept running into the same issue on vanilla OpenBSD 7.5. I found this reddit thread which contained the solution: https://www.reddit.com/r/openbsd/comments/yew0ri/keep_getting_a_fatal_protection_fault_in/
The solution was to switch the drives over from IDE/virtio as standard, over to SATA for both cdrom and mass storage. This allowed me to install the system.
