So far I can use VNC to install Windows, but I've been unable to get the networking working. I will provide details below, and include a summary up here. On the guest, I have installed the latest version of winvirtio, and I have configured static IP addressing. The guest can ping itself, but not the host machine or anything external. It is worth noting that I am also currently running a CentOS guest, and this can connect to both the host and the outside world with no issues. > > Host: FreeBSD 11.0-RELEASE > Guest: Tried both Windows Server 2016 Essentials and Windows Server 2012 Standard > > bhyve command: > bhyve -c 1 -H -w -m 3G -s 0,hostbridge -s 3,ahci-cd,/iohyve/ISO// -s '4,ahci-hd,/dev/zvol/zroot/iohyve/win12/disk0,sectorsize=512' -s 10,virtio-net,tap2 -s '11,fbuf,tcp=0.0.0.0:5902,w=800,h=600,wait' -s 12,xhci,tablet -s 31,lpc -l com1,/dev/nmdm3A -l bootrom,/iohyve/Firmware/BHYVE_UEFI.fd/BHYVE_UEFI.fd ioh-win12 > I noticed something here.
