Hello, In a qemu VM, when trying to have networking using the virtio-net-device device, assigning an IP address to the vtnet0 device gets ifconfig stuck in an uninterruptable state. Tried it with qemu 2.8.0, 2.8.1 and 2.9.0. FreeBSD version: # uname -a FreeBSD build-aarch64.marvin.harmless.hu 12.0-CURRENT FreeBSD 12.0-CURRENT #0 r322371: Thu Aug 10 21:09:06 CEST 2017 toor@marvin.harmless.hu:/tank/rpi3/obj/arm64.aarch64/tank/rpi3/src/sys/GENERIC-NODEBUG arm64 vtnet0 device: vtnet0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=80028<VLAN_MTU,JUMBO_MTU,LINKSTATE> ether 52:54:00:12:34:56 media: Ethernet 10Gbase-T <full-duplex> status: active nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384 vtnet0: <VirtIO Networking Adapter> on virtio_mmio30 vtnet0: Ethernet address: 52:54:00:12:34:56 QEMU cmdline: qemu-system-aarch64 -m 4096M -cpu cortex-a57 -M virt \ -accel tcg,thread=single \ -bios QEMU_EFI.fd -serial telnet::4444,server -nographic \ -drive if=none,file=${image},id=hd0,format=raw \ -device virtio-blk-device,drive=hd0 \ -device virtio-net-device,netdev=net0 \ -netdev tap,id=net0,ifname=tap0,script=/tank/rpi3/build/qemu-ifup.sh Should be easy to reproduce, just add a vtnet device into a qemu-system-aarch64 VM, and try assigning an IP.
