I am reading 'Deploying Rails Applications' and want to create a Rails clustered deployment setup as described in page 141:
Host: Ubuntu server
Guests: 2 Ubuntu vms, each with Nginx on port 80, a few mongrels (app server for rails) and MySQL
What open source virtualization software do you recommend for this purpose?
I am trying virtualbox but heard good things about KVM.
I have some questions regarding vbox and posted them on vbox forums - http://forums.virtualbox.org/viewtopic.php?f=7&t=30427
(in case anyone want to help there)
