# KVM tools

This repository contain scripts for managing KVM hypervisors used with DRBD and LVM.

It contains the following scripts.

- add-vm: create DBRD volumes and virtual machines.
- kvmstats: gives informations about defined virtual machines.

## Install

Copy the scripts to /usr/local/sbin:

~~~
install -m 0755 add-vm /usr/local/sbin/add-vm
install -m 0755 kvmstats /usr/local/sbin/kvmstats
~~~

Edit configuration in /etc/evolinux/add-vm.cnf:

~~~
masterKVMIP=192.168.0.X
slaveKVMIP=192.168.0.Y

You can override this by adding a Bash array in /etc/evolinux/add-vm.cnf, eg:

~~~
disks=("VG1" "VG2")
~~~
