Cantivo Linux is a distribution and platform for desktop/server virtualization using the KVM hypervisor and SPICE protocol, managed from an intuitive Web interface.

It's All Good is a simple service monitoring framework to make it easy to monitor various services on a server. Its API is dead simple, and a handful of modules are already available for common things like disk usage, checking that SMTP is running, SSL certs are valid, or a page's contents. It can easily be used with a service like Pingdom so that you can monitor your servers' health with only 1 alert (which you can get for free). It's small, compact, fast, and loads nicely on most mobile devices including your iPhone or Android device.
