Windows Server 2016 as guest on bhyve 4k emulated drive

[Thibault Noel]

Hi Guys !

I tried to use windows 10 on Bhyve, and I have a coredump when I try to use
VNC.

My command line is :
bhyve -c 4 -m6G -Hl bootrom,BHYVE_UEFI_20160526.fd -s 0,hostbridge -s
1:0,ahci-hd,/dev/zvol/tank/VM/windows.img,sectorsize=512 -s
5:0,ahci-hd,/var/tmp/windows.disk -s 7:0,virtio-net,tap0 -s 8:0,fbuf,tcp=
192.168.1.10:5900,w=640,h=480,wait Windows10
