#aptitude install lxc

#aptitude install bridge-utils libvirt-bin debootstrap

adicionar a /etc/fstab:
#cgroup /sys/fs/cgroup cgroup defaults 0 0
#mount /sys/fs/cgroup

criar o contentor:
lxc-create -n servidorweb -t debian

fazer chroot e criar o dev tty1 que não foi criado:
#chroot /var/lib/lxc/servidorweb/rootfs/
#mknod tty1 c 4 1

adicionar as seguintes linhas a /var/lib/lxc/servidorweb/config:
# <<<< ADD THOSE LINES
lxc.utsname = vm0
lxc.network.type = veth
lxc.network.flags = up
lxc.network.link = br0
# lxc.network.name = eth0
lxc.network.hwaddr = 00:FF:12:34:56:78
lxc.network.ipv4 = 10.0.0.110/24

para dois interfaces em bridges diferentes:
lxc.network.type = veth
lxc.network.flags = up
lxc.network.link = br0
lxc.network.name = eth0
lxc.network.ipv4 = 10.60.0.84/23
lxc.network.mtu = 1500
lxc.network.hwaddr = AC:DE:48:00:00:54
lxc.network.veth.pair = veth84

lxc.network.type = veth
lxc.network.flags = up
lxc.network.link = br1
lxc.network.name = eth1
lxc.network.mtu = 1500
lxc.network.ipv4 = 193.198.212.253/22
lxc.network.hwaddr = AC:DE:48:00:D4:FD
lxc.network.veth.pair = veth212253

criar a bridge

iniciar o contentor:
lxc-start -n servidorweb

pstree - árvore de processos

remover um contentor:
lxc-destroy -n servidorweb

ATENÇÃO:
antes de iniciar as máquinas virtuais pela primeira é necessário criar os seguintes nós:
sudo chroot /var/lib/lxc/myfirstcontainer/rootfs
mknod -m 666 /dev/tty1 c 4 1
mknod -m 666 /dev/tty2 c 4 2
mknod -m 666 /dev/tty3 c 4 3
mknod -m 666 /dev/tty4 c 4 4
mknod -m 666 /dev/tty5 c 4 5
mknod -m 666 /dev/tty6 c 4 6

para que o acesso por ssh possa ser utilizado é necessário criar as chaves seguintes:
echo y | /usr/bin/ssh-keygen -t rsa -N "" -f /etc/ssh/ssh_host_rsa_key
echo y | /usr/bin/ssh-keygen -t dsa -N "" -f /etc/ssh/ssh_host_dsa_key

++++++++++++++++++para iniciar uma máquina automaticamente
criar um symlink em /etc/lxc/auto/ a apontar para a config da máquina a arrancar
#ln -s /var/lib/lxc/lxc_dc1/config /etc/lxc/auto/lxc_dc1
