How to create a LXC Debian root filesystem for VNX

DRAFT, DRAFT, DRAFT...not finished yet


Basic installation

Follow this procedure to create a LXC Debian based root filesystem for VNX. The procedure has been tested creating a Debian Squeeze (6) over an Ubuntu 13.10 host.

  • Create the rootfs with:
  • lxc-create -t ubuntu -n vnx_rootfs_lxc_debian
    

    Note1: The default username/password is root/root.
    Note2: use linux32 command to create a 32 bits image from a 64 bits machine, that is:

    linux32 lxc-create -t debian -n vnx_rootfs_lxc_debian
    
  • Move the rootfs to VNX filesystems directory:
  • mv /var/lib/lxc/vnx_rootfs_lxc_debian/ /usr/share/vnx/filesystems/
    
  • Edit the rootfs configuration file (/usr/share/vnx/filesystems/vnx_rootfs_lxc_debian/config) to reflect the directory change:
  • lxc.rootfs = /usr/share/vnx/filesystems/vnx_rootfs_lxc_debian/rootfs
    lxc.mount  = /usr/share/vnx/filesystems/vnx_rootfs_lxc_debian/fstab
    
  • Start the new rootfs to configure it and install new software:
  • lxc-start -n vnx -f /usr/share/vnx/filesystems/vnx_rootfs_lxc_debian/config
    
  • Once the VM has started, make login (root/root) and:
    • Add VNX user and change the passwords:
    • adduser vnx
      adduser vnx sudo
      passwd root
      
    • Update the system:
    • apt-get update
      apt-get dist-upgrade
      
    • And install additional software, for example (list taken from here):
    • apt-get --no-install-recommends install -y adduser apt-utils iproute netbase sudo iputils-ping iptables rsyslog
      apt-get install --no-install-recommends openssh-blacklist openssh-blacklist-extra openssh-server 
      apt-get install net-tools ifupdown sockstat
      apt-get install wget less lsof screen apt-utils nano telnet inetutils-ping psmisc
      apt-get install aptsh traceroute nmap apache2 wget tcpdump vim
      
    • Change VM name in hosts and hostname files:
    • vi /etc/hosts         # change name to vnx
      vi /etc/hostname      #     "
      
    • Important: edit /etc/network/interfaces and coment "inet dhcp" lines to avoid delays at startup.
  • Stop the VM with:
  • halt
    
  • Optionally, create a short link to the rootfs:
  • cd /usr/share/vnx/filesystems
    ln -s vnx_rootfs_lxc_ubuntu-13.10 rootfs_lxc
