Earlier this year IBM launched the Virtualization@IBM blog and I'm pleased to have contributed a guest post on KVM Architecture!
KVM Architecture: The Key Components of Open Virtualization with KVM explains the open virtualization stack built around KVM. It highlights the performance, security, and management characteristics of the architecture. I hope it is a good overview if you want a quick idea of how KVM works.
You can follow @Linux_at_IBM and @OpenKVM on Twitter for more official updates. For example, the Open Virtualization Alliance that HP, IBM, Intel, Red Hat, and many others are coming together around.
