D'oh! I just realised you're not supposed to use the other network
options when using `--tap-fd`!
I was then able to browse the web from crosvm, like this:
- Add pkgs/os-specific/linux/spectrum/rootfs/etc/resolv.conf with e.g.
"nameserver 8.8.8.8".
- Configure the virtual eth0 in the VM setup script:
foreground { ifconfig eth0 10.0.0.2 up }
foreground { route add default gateway 10.0.0.1 }
- Enable NAT in configuration.nix, e.g.
networking.nat = {
enable = true;
externalInterface = "eno2";
internalIPs = [ "10.0.0.0/8" ];
};
- Start the VM.
- Run "sudo ifconfig tap0 10.0.0.1 up" on host.
- Run firefox in VM to browse the web :-)
