Debian vm configuration

Template file

Copy the following file in the template folder of lxc:

https://raw.github.com/ArnaudValensi/lxc-ovh/master/files/templates/lxc-debian-custom

VM creation

lxc-create -n name -t debian-custom

Host configuration

Add this :

       post-up echo 1 > /proc/sys/net/ipv4/ip_forward
       post-up iptables -t nat -A POSTROUTING -s 192.168.10.0/24 -o eth0 -j MASQUERADE

   auto br0
   iface br0 inet static
       address 192.168.10.1
       netmask 255.255.255.0
       bridge_ports none
       bridge_stp off
       bridge_fd 0
       bridge_maxwait 5

The file should look like this :

   auto eth0
   iface eth0 inet static
       address 91.123.123.123
       netmask 255.255.255.0
       network 91.123.123.0
       broadcast 91.123.123.255
       gateway 91.123.123.254
       post-up echo 1 > /proc/sys/net/ipv4/ip_forward
       post-up iptables -t nat -A POSTROUTING -s 192.168.10.0/24 -o eth0 -j MASQUERADE

   auto br0
   iface br0 inet static
       address 192.168.10.1
       netmask 255.255.255.0
       bridge_ports none
       bridge_stp off
       bridge_fd 0
       bridge_maxwait 5

Autostart VMs

Copy the following file in /etc/init.d/:

https://raw.github.com/ArnaudValensi/lxc-ovh/master/files/init.d/lxc

Then:

$ chmod +x /etc/init.d/lxc
$ update-rc.d lxc defaults

Now to autostart a vm you can add 1 in a file named autostart in the vm folder:

echo "1" > /path/to/lxc/myvm/autostart
