### Open Build Service (OBS)
Our build tool, building all of our packages as well as ones for SUSE Linux Enterprise, Arch, Debian, Fedora, Scientific Linux, RHEL, CentOS, Ubuntu, and more.
### openQA
Automated testing for *any* operating system, that can read the screen and control the test host the same way a user does.
http://open.qa/
### YaST
The best/only comprehensive Linux system configuration & installation tool.
https://yast.opensuse.org/documentation
### Kiwi
Create Linux images for deployment on real hardware, virtualisation, and now even container systems like Docker. Kiwi is the engine that builds the openSUSE release images.

## Virtualization tool
https://docs.fedoraproject.org/en-US/Fedora/23/html/Virtualization_Getting_Started_Guide/sec-Other-Useful-tools.html
https://github.com/kvmtool/kvmtool kvmtool is a lightweight tool for hosting KVM guests. As a pure virtualization
tool it only supports guests using the same architecture, though it supports
running 32-bit guests on those 64-bit architectures that allow this.

## Security
### Secure Boot

* [Openstack] Allow Secure Boot (SB) for QEMU- and KVM-based guests :

### Ideas from hackernews blog post (as used by Red Hat)
* Aggressively compile out unused features/devices.
* Confine each VM with separate SELinux contexts (sVirt).
* Run qemu as a special non-root user.
* Use seccomp to confine the system calls.
* Pass in pre-opened file descriptors to qemu, so qemu doesn't need to open files (helps with writing tightly confined SELinux policy).
* Run qemu in a cgroup.
* Run qemu-img with resource limits.
* Compile qemu with all hardening features enabled like RELRO, PIE, etc.
* Audit the code manually and with Coverity.
* Take security reports seriously and have a fast patching mechanism (you can effectively "live patch" qemu by migrating a VM off the old qemu and on to the new qemu).
Probably more that I've forgotten about ...
