#   Virtual machine creation and emulation

# AUTHOR:
#   Olaf Reitmaier &lt;olafrv@gmail.com&gt; (20/07/2009)
#
# HOW-TO:
#   Put this on you /etc/network/interfaces
#   if the real NIC in configured via dhcp:
#
#     auto lo
#     iface lo inet loopback
#
#     auto eth1
#
#     auto br0
#     iface br0 inet dhcp
#        bridge_ports eth1
#
#   Put this on you /etc/network/interfaces if
#   the real NIC in configured with and static IP:
#
#    auto lo
#    iface lo inet loopback
#
#    auto eth1
#
#    auto br0
#    iface br0 inet static
#        address 172.26.98.50
#        netmask 255.255.248.0
#        gateway 172.26.96.1
#        bridge_ports eth1
#
#
#   Then execute the following commands:
#     cp qemu.sh ~
#     apt-get install -y bridge-utils and kqemu-common kqemu-source
#     cd /usr/src/
#     bzip2 -d kqemu.tar.bzip2
#     tar xvf kqemu.tar
#     cd modules/kqemu
#     ./configure &amp;&amp; make &amp;&amp; make install
#     cd ~
#     sudo ./qemu.sh
