Massive Deployment of Xen enabled Virtual Cluster with Diskless Remote Boot Linux

Test Environment

  • VMWare Server 1.0.3
  • VMWare Image debian 4.0r1 as DRBL Server
  • VMWare Image without disk as DRBL Client

Pre-installation

  • First, install Xen Hypervisor and Xen enabled Linux Kernel and then reboot
    root@drbl-xen-srv:~# uname -a
    Linux drbl-xen-srv 2.6.18-6-686 #1 SMP Sat May 24 10:24:42 UTC 2008 i686 GNU/Linux
    root@drbl-xen-srv:~# apt-get install xen-hypervisor-3.0.3-1-i386-pae linux-image-2.6.18-6-xen-vserver-686 xen-tools libc6-xen
    root@drbl-xen-srv:~# update-grub
    root@drbl-xen-srv:~# reboot
    
    • Note: If you did not install libc6-xen, you might have "4gb seg fixup" error message keep showing up while booting.
  • Choose Xen to boot at GRUB menu

Install and Configure DRBL

  • Download GPG-KEY-DRBL and add GPG key via apt-key
    root@drbl-xen-srv:~# wget http://drbl.nchc.org.tw/GPG-KEY-DRBL
    root@drbl-xen-srv:~# apt-key add GPG-KEY-DRBL
    
  • Add DRBL repository URL
    root@drbl-xen-srv:~# echo "deb http://free.nchc.org.tw/drbl-core drbl stable" > /etc/apt/sources.list.d/drbl-sources.list
    
  • Use drblsrv command to setup DRBL server. Here we choose linux-image-2.6.18-6-486 as default DRBL PXE kernel image
    root@drbl-xen-srv:~# /opt/drbl/sbin/drblsrv -i

  • Use Thin Client VMWare Image to test DRBL
