We handled this a little differently. One thing that is important is the
environment and install process so we take a snapshot of a virtual
machine that has the base OS installed. We make a copy of the snapshot,
boot the copy, install all the server packages and check that the
installation went correctly. Then we run the tests against the server
installed in the VM. At the end of the test we throw away the VM and
wait for the next checkin. 

We for all of the above we are using KVM under Linux (Ubuntu
specifically) to manage the VMs.
