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

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

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

opennebula ALL = NOPASSWD: /usr/sbin/xm
#Defaults    requiretty
