Management KVM machines.

1. Install following packages:

   1.1) For Debian, Ubuntu:

    1.1.1) Host: apt-get install uml-utilities bridge-utils arp-scan kvm ssh
   
    1.1.2) Guest: apt-get install dnsmasq ssh
   

2. Add user into group kvm: usermod kvm -G <user_name>

3. Create image file: kvm-img create -f qcow2 -o preallocation=metadata,cluster_size=2M,encryption=off ./ubuntu-server-10.04-64.img 500G

4. Convert image file: kvm-img convert -O qcow2 -o preallocation=metadata,cluster_size=2M,encryption=off ./ubuntu-server-10.04-64.img ./ubuntu-server-10.04-64.img.new

5. For bridge interface.
