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
