# OpenBSD vmm(4) example setup
The idea of this repo is to setup an example vmm(4) environment to run VMs over OpenBSD, with OpenBSD.
For debian on vmm(4) you can also see @vext01:

# 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 and runs the DHCP server on 10.10.10.255
## hostname.bridge0
This file bridges your network so the VMs can talk to vether0 to get a DHCP address and be forwarded to the internet.
In the new syntax, ```add vether0``` has been removed and replaced with ```interface bridge0``` so now the network looks like this:
``` vm ---> bridge0 ---> vether0 ---> internet```
## 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.
## Makefile usage
Assuming you have comp6X.tgz installed.
