Hi, A good spot, my launch command doesn't include the virtio-win ISO that contains the RedHat net-kvm driver. However, this is mostly just due to a limitation in iohyve (or my understanding of it at least) in that it can only mount a single CD at once. I did in fact install the driver, by running "iohyve install win16 virtio-win.iso" which then mounted it for that session. However, successive "iohyve start win16" invocations did not continue to mount this ISO. In particular, I used virtio-win-0.1.126.iso with driver net-kvm/windows 2k16/amd64 for my attempt with Server 2016 and the 2k12r2/amd64 driver for Server 2012 R2. Thanks, Jonathan.

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. > > In my setup phase for Windows 2016 DC , > > I used > > > /usr/sbin/bhyve -A -c 4 -m 4G -w -H -s 3,ahci-cd,./.iso/virtio-win-0.1.96.iso -s 4,ahci-hd,windows2016.img -s 5,virtio-net,tap15 -s 29,fbuf,tcp=0.0.0.0:5900,w=1024,h=768,wait -s 30,xhci,tablet -s 31,lpc -l com1,/dev/nmdm15A -l bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd windows2016guest & > > Have you install the red-hat virtual ethernet driver? > >> ifconfig output: >> em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 >> options=4219b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MAGIC,VLAN_HWTSO> >> ether e0:69:95:a2:f1:d9 >> inet 46.105.xxx.xxx netmask 0xffffff00 broadcast 46.105.124.255 >> inet6 fe80::e269:95ff:xxxx:f1d9%em0 prefixlen 64 scopeid 0x1 >> inet6 2001:41d0:2:xxxx::1 prefixlen 56 >> nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL> >> media: Ethernet autoselect (100baseTX <full-duplex>) >> status: active >> lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384 >> options=600003<RXCSUM,TXCSUM,RXCSUM_IPV6,TXCSUM_IPV6> >> inet6 ::1 prefixlen 128 >> inet6 fe80::1%lo0 prefixlen 64 scopeid 0x2 >> inet 127.0.0.1 netmask 0xff000000 >> nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL> >> groups: lo >> bridge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 >> ether 02:cf:0c:8f:13:00 >> inet6 fd00::ffff prefixlen 112 >> inet 10.0.0.254 netmask 0xffffff00 broadcast 10.0.0.255 >> nd6 options=1<PERFORMNUD> >> groups: bridge >> id 00:00:00:00:00:00 priority 32768 hellotime 2 fwddelay 15 >> maxage 20 holdcnt 6 proto rstp maxaddr 2000 timeout 1200 >> root id 00:00:00:00:00:00 priority 32768 ifcost 0 port 0 >> member: tap2 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP> >> ifmaxaddr 0 port 7 priority 128 path cost 2000000 >> member: tap1 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP> >> ifmaxaddr 0 port 5 priority 128 path cost 2000000 >> member: tap0 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP> >> ifmaxaddr 0 port 4 priority 128 path cost 2000000 >> pflog0: flags=0<> metric 0 mtu 33160 >> groups: pflog >> tap0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500 >> description: iohyve-centos >> options=80000<LINKSTATE> >> ether 00:bd:5d:d3:e8:00 >> nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL> >> media: Ethernet autoselect >> status: active >> groups: tap >> Opened by PID 96206 >> tap1: flags=8902<BROADCAST,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500 >> description: iohyve-win16es >> options=80000<LINKSTATE> >> ether 00:bd:61:ab:eb:01 >> nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL> >> media: Ethernet autoselect >> status: no carrier >> groups: tap >> tap2: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500 >> description: iohyve-win12 >> options=80000<LINKSTATE> >> ether 00:bd:c9:1a:59:02 >> nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL> >> media: Ethernet autoselect >> status: active >> groups: tap >> Opened by PID 1911 >> >> It is using NAT with PF to reach the internet.
