Offload VM Cloning from KVM to the Back-end Storage

A few weeks ago, I addressed the concept of using the back-end storage to clone RHEL boot LUNs as opposed to repeated Kickstarts.  The reasoning is simple enough – cloning on the backend is significantly faster that creating from scratch.  Work smarter, not harder.. Right?

So what happens when we apply the same logic to individual virtual machines? In a word?

“Magic”. Continue reading “Offload VM Cloning from KVM to the Back-end Storage”

Don’t kickstart – Clone!!!!

So you have the perfect “Golden Image” built by way of a kickstart file.  You have a dedicated network for your installs and your boot disk is a NetApp LUN.  You’ve set every conceivable tunable to ensure that every subsequent build via PXE install is under 10 minutes, including post configurations in “%post”.

Guess what.  I can beat it by 9.5 minutes.  Consistently. Continue reading “Don’t kickstart – Clone!!!!”

At the oVirt Workshop in Santa Clara, CA….

Captain KVM is spending part of this week in Santa Clara, CA for the oVirt Workshop along with about 80 other attendees all eager to dive into all of the various projects that oVirt represents.

There are representatives from SUSE, IBM, NetApp, Cisco, Canonical, Red Hat, Intel, and others – as well as some non-corporate folks here as well. This week is dedicated to getting board members together, introducing new members of the oVirt community, and getting specific people involved in specific projects.
