Does it?

But I don't understand how why it is probed successfully. the "-vga 
none" option should remove any vga capability in the host. I have tried 
this successfully on an OpenBSD guest and part-successfully on a NetBSD 
guest (I had to comment all references to /usr/libexec/getty Pc). Why 
this is not the case on a FreeBSD guest puzzles me. Is it a qemu bug? A 
FreeBSD bug?

1) because I don't need it and 2) to test if qemu works as intended.
