Based on the output from the following command you can easily determine if a Linux machine has 32 bit or 64 bit kernel:

uname -a

If you see something like x86_64, then your running with a 64 bit kernel. If you use see i386/i486/i586/i686 it’s a 32 bit kernel.

Google recently announced the first beta release of Ganeti, an open source virtual server management software built on top of Xen and other open source software. Naturally, since I’ve been using VMWare for the last year or so I was curious about Ganeti.

What is Ganeti?

In short, Ganeti is a cluster virtualization platform based on Xen. An “intent to package” or ITP has been filed with Debian which describes Ganeti as “a virtual server cluster management software tool built on top of the Xen virtual machine monitor and other Open Source software. After
setting it up it will provide you with an automated environment to manage highly available virtual machine instances.”
