For root servers Hetzner provides an additional special "AX" (AMD li= ne) flavored FreeBSD 13 rescue image - though I am not actually sure what the difference is.=20 For the VPS's there is only one FreeBSD rescue image, which includes only a= few necessary modules but not virtio and which works without issue. They do not actually have a FreeBSD installation option for the VPS's - you= can only install FreeBSD via the rescue image (either manually or running bsdinstall[image]) - but mostly what I want to say is that they don't know = what OS you're actually running and there therefore shouldn't be any special KVM settings and it should be the same thing a Linux OS sees. At most the provi= ded bsdinstall blacklists virtio. As far as I have been able to tell, this is the only issue with this (virtu= al) hardware, it even performs surprisingly well.
