Simple Git-over-SSH shared repositories

Git is one of the more popular of the many revision control systems available. One of the many great features of Git is that you can setup a simple shared repository very quickly on any conveniently available Linux system. Git is able to do this easily because it knows how to access files over SFTP. By simply creating a shell account on a system with an OpenSSH server we can copy repositories to that account and share them between co-workers and sandboxes. Read this article for an introduction to Git and a tutorial on Git-over-SSH setup.

KVM-QEMU, QCOW2, QEMU-IMG and Snapshots

The QCOW2 format is the most powerful format supported by KVM-QEMU.

In this article we will look at some of the advanced features available in the QCOW2 format through the QEMU Image tool. We create a QCOW2 image, create snapshots within the image, create an image that is based on a backing file and copy an image to get rid of the reference to the backing file.
