OpenBSD vmm(4) example setup

The idea of this repo is to setup an example vmm(4) envorioment to run VMs over OpenBSD, with OpenBSD.

WARNING: This will override your files if exists

hostname.vether0

You can set your VMs network here, for now is 10.10.10.0/24

pf.conf

A typical pf.conf, $ext_if are our inet interfaces, and $int_if are our 'internal', in this case, the internals interfaces are the ones connected to VMs, in this case vether0 and tapX. You need to edit this according to your machine.

sysctl.conf

Now our machine is our VMs GW, so we need to permite the ip forwarding.

dhcpd.conf

A regular dhcpd setup, for our VMs, setting our network and nameservers.

vm.conf

Our VMs file, has comments, this is the main file, you need to edit this to your taste.
