David, How do your drivers handle a virtio-based CD-ROM? qemu by default uses IDE, or can be configured to use SATA CD-ROM devices, however, OpenBSD's vmd(8) strictly uses a virtio-based CD-ROM.
I don't know how the interactions end up differing between hard drive and CD-ROM access in that case, but its something to look at if you weren't aware of it. >From OpenBSD 6.9 booted using vmd(8) on OpenBSD 7.0.
