 **NLVMI** stands for **Native Lightweight Vm Management Interface**
 
+As the name suggests, the goal of this project is to build a lightweight interface for handling KVM in a home or small business environment.
 
-It is composed of a few parts: <br/>
+It uses standard linux tools as much as possible and its code is explicitely written to be easy to understand and extend.
-The bash script<br/>
+Yes, the code could probably be written nicer in one way or another, but as it seems, more complexity isn't really needed. :-)
-The suid wrapper<br/>
+
-The php interface<br/>
+Patches are very welcome!
-The js helper<br/>
+
-Other parts which are used:<br/>
+As of now, nlvmi is capable of the following things:<br/>
-Bootstrap<br/>
+-Defining, starting/stopping vms as unprivileged users (every vm could run as different unix user)<br/>
-NoVNC<br/>
+-Creating (up to 3) tap interfaces and adding them to defined network bridges<br/>
-QEMU<br/>
+-Handling vms on remote servers via ssh<br/>
-and a few linux tools<br/>
+-Novnc access to VMs<br/>
+
+A few things are planned to get added:<br/>
+-handling of qcow images (maybe even minimal lvm management one day)<br/>
+-live migration between hosts<br/>
+-initd script / systemd unit to start/stop vms on host reboots (autostart can already be achieved via a cron @reboot entry)<br/>
+-some server overview with current usage<br/>
+-a mac-address generator<br/>
+
+These things are not in scope:<br/>
+-measuring usage of vms to bill customers or such<br/>
+-beeing feature complete. Qemu can do just too much! But there is a custom field for uncommon configurations<br/>
+-automatic failover between hosts. That would need a daemon running and we should not reinvent the wheel. Look at DRDB and pacemaker. Patches are welcome to handle the basics of them!<br/>
