If you transfer qcow2 images very frequently across OpenStack Clouds or between KVM and Openstack environments, they can quickly grow larger. Luckily qcow2 image size can be decreased to reasonable values using qemu-img tool. During image conversion the empty sectors are detected and suppressed from the destination image. Below we present how to shrink Openstack/KVM qcow2 image.
Kali Linux (formerly known as BackTrack Linux) is an open-source, Debian-based Linux distribution designed for advanced Penetration Testing and Security Auditing. Kali Linux contains dozens of tools targeted towards various information security tasks, such as Penetration Testing, Security Research, Computer Forensics, and Reverse Engineering. Kali Linux is a multi-platform solution, accessible and freely available to information security professionals and hobbyists.
Kali Linux can run as a bare-metal server, can be booted from a live CD or live USB, or it can run as KVM virtual machine or OpenStack instance using qcow2 image.
Below you can purchase ready to use Kali Linux OpenStack / KVM 64bit qcow2 images. There are two types of image:
- OpenStack.qcow2 image – cloud-init service enabled, SSH password-based/key-based login, local console/GUI login
- KVM.qcow2 image – SSH password-based login, local console/GUI login

Some Linux distributions (for example: RedHat) have aliases configured in the system, especially for root user, which modify basic command line operations like: cp, mv by adding “-i” parameter to prevent user from accidental overwriting or deleting files (interactive mode). This can be disturbing, especially when we are dealing with many files at a time. To get rid of this issue we can modify aliases in the system to disable interactive mode.
OpenStack Snapshots can be utilized to backup Instance before some critical changes are made on Instance OS or to migrate Instance to the new OpenStack Cloud.
In this tutorial we will create snapshot from existing Instance to launch it in different Cloud, but you can also create snapshot just to backup the Instance and restore it’s state later in the same Cloud, if needed.
