Up and Running with oVirt 4.1 and Gluster Storage
Last month, the oVirt Project shipped version 4.1 of its open source virtualization management system. With a new release comes an update to this howto for running oVirt together with Gluster storage using a trio of servers to provide for the system's virtualization and storage needs, in a configuration that allows you to take one of the three hosts down at a time without disrupting your running VMs.
If you're looking instead for a simpler, single-machine option for trying out oVirt, your best bet is the oVirt Live ISO page. This is a LiveCD image that you can burn onto a blank CD or copy onto a USB stick to boot from and run oVirt. This is probably the fastest way to get up and running, but once you're up, this is definitely a low-performance option, and not suitable for extended use or expansion.
Read on to learn about my favorite way of running oVirt.
oVirt, Glusterized
Prerequisites
Hardware: You’ll need three machines with 16GB or more of RAM and processors with hardware virtualization extensions. Physical machines are best, but you can test oVirt using nested KVM as well. I've written this howto using VMs running on my "real" Continue reading

Amazing Discovery: Stability Matters
Here’s an interesting blog post (particularly as it’s coming from a well-known cloud evangelist): at the infrastructure level stability matters more than agility or speed-of-deployment. Welcome to real world ;)
My personal highlights of 2016 for the Asia-Pacific Bureau and what’s coming up in 2017
The year 2016 was indeed a successful year for the Internet Society (ISOC) Asia-Pacific (APAC) Team. We were able to leverage many opportunities throughout the year across the region, and together with our members, chapters and partners, we worked towards ensuring that the Internet kept growing and evolving.
For me personally, there were a couple of things that stood out. One was InterCommunity 2016 where we had 11 nodes located throughout the region engaged in robust intra-regional discussions on topical issues.
Liveblog: DockerCon 2017 Day 2 Keynote
This is a liveblog of the day 2 keynote (general session) of DockerCon 2017 in Austin, TX. For a look at what was announced or discussed in the day 1 keynote yesterday, see this liveblog. You can also see all DockerCon 2017-related posts by browsing the posts tagged with “DockerCon2017” (see the links at the bottom of this page). Before the keynote starts, there’s some nice live music playing; a welcome change (in my opinion) from yesterday’s video game.
At 9:03am, Ben Golub takes the stage to kick off the day 2 general session. He starts off by reviewing some proposed Docker logos, with a hint toward an announcement at the end of the session (presumably around changing Docker’s logo).
Golub then transitions into the meat of the general session presentation, which (understandably) is focused on Docker in the enterprise. He reviews the usual slide with notable logos from Docker customers. He also discusses some results from a company called ETR, which (apparently) shows Docker is “off the charts” in terms of adoption and market penetration within the enterprise. Golub also debunks the bi-modal IT structure model, saying that Docker’s customers only want one thing: speed (as in moving faster, Continue reading
FPGAs To Shake Up Stodgy Relational Databases
So you are a system architect, and you want to make the databases behind your applications run a lot faster. There are a lot of different ways to accomplish this, and now, there is yet another — and perhaps more disruptive — one.
You can move the database storage from disk drives to flash memory, You can move from a row-based database to a columnar data store that segments data and speeds up accesses to it. And for even more of a performance boost, you can pull that columnar data into main memory to be read and manipulated at memory …
