IncludeOS/VirtualBox - DHCP timeout

[mjbright]

Trying to run an IncludeOS/acorn image on Virtualbox DHCP is timing out so an unusable static ip is assigned, see below.

Host is running Fedora27, VirtualBox 5.1.30.

Network adaptor was configured as Host-only adapter / vboxnet0. VBoxNet DHCP is running on vboxnet0. mjb 14069 13886 0 10:03 ? 00:00:00 /usr/lib/virtualbox/VBoxNetDHCP --ip-address 192.168.56.100 --lower-ip 192.168.56.101 --mac-address 08:00:27:14:74:70 --netmask 255.255.255.0 --network HostInterfaceNetworking-vboxnet0 --trunk-name vboxnet0 --trunk-type netflt --upper-ip 192.168.56.254

Console output shows DHCP is timeing out:

Tested with e1000 driver (Intel PRO/1000 MT Server) and both NAT and Host-only networks are working fine for me. Does time out with VirtioNet for me.

Tried the same image on VirtualBox (macOS). Works fine with e1000 driver, but times out on VirtioNet.

After more investigation it seems like some things aren't supported with virtionet in VirtualBox

VirtioNet::legacy_handler() isn't being called. Proof (in VirtioNet constructor):

  Timers::periodic(3s, 1ms, [this](auto){
    this->legacy_handler();
  });

This makes the network working (DHCP resolution, demo_service TCP works etc).
