=====Improve boot speed KVM guests=====

  * Change grub timeout. <code>vi /etc/grub.conf
default=0
timeout=1
serial --unit=0 --speed=115200
terminal --timeout=0 serial console</code>
  * Disable PXE boot if you don't need it. ('rom bar=off' doesn't work in libvirt?)
  * disable unnecessary services
