Making it work in 9Front post-install:

File -> Preferences -> Host-only Networks -> VirtualBox Host-only
Adapter -> DHCP Server

Take note of the Server Mask and the IP range, you'll use these to set
up a /lib/ndb/local something along the lines of:

ipnet=9front ip=192.168.56.0 ipmask=255.255.255.0
     auth=cirno
     cpu=cirno
     smtp=cirno

sys=cirno ether=080047472abc ip=192.168.56.102

Set an arbitrary address within range for Adapter 1, this will be ether1
and Adapter 2 should be ether0 (for some reason I had to flip them).

Adapter 1's address is the remote access address, I just leave the
Adapter 2 to be auto-configured by 9Front via DHCP and provide internet
access that way.

To ensure ether1 comes up:
Create /cfg/$sysname/cpustart and add:

bind -a '#l1' /net.alt
bind -b '#I1' /net.alt
ip/ipconfig ether /net.alt/ether1


Hopefully this helps someone.

Cheers,
