Open Issues

  • Network Address Translation - What is the load?<br\>
  • Virtual Machine Isolation - Prohibit internal network connectivity with IPTables.<br\>
  • Image repository - Storage Area Network or distributed over worker nodes.<br\>
  • Policy document<br\>

Infrastructure

I am setting up a testbed to investigate technical issues related to virtual machine management.

Hardware and Operating Systems

  • 2 Dell 1950 machines, dual CPU, 4 cores per CPU
    • One machine has a Centos-5 installation
    • One machine has a Debian-squeeze installation

Software

  • Centos-5 comes with Xen 3.0
  • Debian-squeeze comes with Xen 3.3
    • Debian-squeeze Xen packages have a problem with tap:aio.
Fix:<br\>
ln -s /usr/lib/xen-3.2-1/bin/tapdisk /usr/sbin<br\>
echo xenblktap >> /etc/modules
  • Opennebula has been installed following this guide
    • A few additional staps were needed:
      • Install rubygems and rubygem-sqlite3
wget ftp://fr.rpmfind.net/linux/EPEL/5/x86_64/rubygem-sqlite3-ruby-1.2.4-1.el5.x86_64.rpm
wget ftp://fr.rpmfind.net/linux/EPEL/5/x86_64/rubygems-1.3.1-1.el5.noarch.rpm

      • Opennebula has to be added to the sudoers file for xm
      • Sudoers should not require a tty
