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”
The Fedora Project, http://fedoraproject.org, released the latest release of their community Linux release. Can’t wait to upgrade and congrats to all involved!!
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!!!!”
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.
For more information on the workshop and oVirt in general, visit the site at http://ovirt.org
Today we’re going to take a look at booting RHEL 6.1 x86_64 from a NetApp iSCSI LUN, but first we’re going to take a look at why we would want to do this in the first place. Sure, it’s cool from a techie standpoint, but to do this in the data center requires a compelling argument. Continue reading “Booting RHEL 6 from NetApp iSCSI”
FTA: Ritchie, also known as “dmr”, is best know for creating the C programming language as well as being instrumental in the development of UNIX along with Ken Thompson.
RIP Mr. Ritchie
Father Of C And UNIX, Dennis Ritchie, Passes Away At Age 70
If you have any interest in developing the ecosystem around the KVM hypervisor, please join us November 1-3 in Santa Clara, CA. Come meet others in the oVirt and KVM community and help shape the future of Open Source Virtualization. Continue reading “Join us at the first oVirt Workshop!!”
If this is a new blog, how is Captain KVM “revisiting” the topic?
In January of this year, I posted an entry for File System Alignment for Linux VMs on my old blog; I’d like to revisit the topic. So, why would anyone want to worry about something like “file system alignment” in the first place? Simple.
Performance. (You do like performance, right?) Continue reading “Revisiting File System Alignment for Linux”
oVirt has been relaunched as of yesterday, and as the official site states, it is ” for anyone that cares about Linux-based KVM virtualization.” oVirt has several corporate sponsers including IBM, Red Hat, NetApp, Intel, Cisco, and SUSE – all of which are providing resources to organize and develop the KVM ecosystem.
If you are interested in joining or contributing to oVirt, there is a workshop scheduled for Nov 1-3 in Sunnyvale, CA – Captain KVM will be there!! See http://ovirt.org for more details. Even if you are unable to attend, it’s a great site if you want to know more about KVM, develop for KVM, or use KVM.
I’m very excited to launch this blog.. As the title suggests, most of my posts will be around the KVM hypervisor as well as virtualization in general. My background is heavy on Linux and storage, so my articles may have slant in those directions.
I hope that as you read this blog you will be encouraged to use KVM, regardless of the Linux distribution, and to also interact with me (and others) on this site.
