No worries, and thanks for all the help so far - it really is appreciated! On the apparmor issue, is this the "right" fix? I modified /etc/apparmor.d/abstractions/libvirt-qemu, adding, /usr/local/bin/qemu-system-x86_64 rmix, /usr/local/share/qemu/** r,
Or is there a "better" (correct) way? As for Windows/Linux vs. macOS guests, I don't think they are usign the same UEFI (are they?). I did reboot the Windows guest, and it looks to be a different "BIOS", agreed? Checking the xml configuration files, they are a bit different (macOS copied below, Windows does not include this). So is it (specifically?) UEFI vs. QEMU (i.e. that is the issue)? <loader readonly="yes" type="pflash">OVMF_CODE.fd</loader> <nvram>OVMF_VARS.fd</nvram> I could definitely be wrong here, but thinking that "stock" UEFI should work / be supported?
