(In reply to Tommy P from comment #24)
Hi Tommy,
now I have networking workaround (disable netmap), I finally did update of my
12.0 VM to 12.1 and applied the VirtIO patch.
I successfully getting Virto devices in my PCI-e config:

I was able to easily flip my Q35 SATA based 12.1 to VirtIO SCSI by editing
/etc/fstab and change SATA ada0p2, atap3 ... to SCSI da0p2, da01p3 ...
Simillary if I wanted to flip to direct VirtIO (rather than via VirtIO SCSI)
you need to edit your /etc/fstab mounts to use vtbd0p2, vtbd0p3 etc
So happy to report that VirtIO patch worked for me with 12.1 rebuilt kernel.
NOTE: the partition numbering here is due to using OVMF which results in FAT32
EFI partition always being on p1 hence root is on p2 in my case.
Thanks again for hard work.
Cheers,
John Hartley.
