Wireless Bridge to the Rescue!

Hi folks,

In the process of rebuilding my lab in the last few days, I ran into a slight issue with the networking. My cable modem is downstairs and almost everything in the house is wireless. Almost everything. My lab is wired. Running cables down the stairs is not an option and I really don’t want to fish cable through the walls.. so what’s a guy to do?

Set up a wireless bridge! Continue reading

Should I Migrate to “the Cloud”?

Hi folks,

I get this question about cloud a lot. Sometimes in those exact words, sometimes in a longer and more drawn out fashion. The answer?

Yes. It just depends on your definition of cloud. Continue reading

Hot Adding Memory to RHEV

Hi Folks,

In our last post, we took a look at the hot add CPU feature for Red Hat Enterprise Virtualization. It wasn’t a brand new feature, but still very important, especially when paired with Hot Add Memory. Which actually is a brand new feature… Continue reading

Hot Adding CPUs to RHEV

Hi folks,

This post means I’m officially back! My new role at the Big Red Fedora started this week and I really wanted to hit the ground running. Plus, RHEV 3.6 launched this month. I want to highlight not only one of the newer features (actually released with version 3.5), but also highlight some of the great work that is being done behind the scenes by one of my colleagues, Sanjay Rao. Continue reading

Back in the Saddle?

Hi Folks,

Lots and lots of good things happening in my little corner of the world.. I’m happy to report that here will be much more RHEV content coming up over the next several months due to a new role that I’m taking on. This will include much more time to write and ultimately help all of you out again. Feel free to hit me up in the comments for RHEV-related things that you think might interest you. I can’t guarantee that I will get to all of them, but I’ll try to incorporate what I can.

Thanks for being patient.

Intro to Heat Templates

Hi Folks,

It’s been a long time right? I mean ~really~ long time since I’ve posted anything. I apologize. It’s been a crazy summer. And Fall. You don’t want the details – trust me, it has very little to do with KVM or storage. I think I’m back to being able to devote some time to helping you kind and patient people out with technology again, so hopefully you haven’t completely abandoned me. 🙂

Today, I’d like to introduce the concept of Heat templates. Essentially, where we left off before was that we’ve got OpenStack up and running, we’ve got some cloud images built, but we’re really not automating anything. This is where Heat comes in.. Continue reading

Meet up at Red Hat Summit?

Hi Folks,

It’s been a while since I’ve posted and I apologize. Things got a little hectic, but all is well. I still don’t have time for a proper post, but if you’re going to be in Boston for Red Hat Summit this week, come by the Red Hat Booth. I’ve got “booth duty” for a little bit each day in the Cloud area. (Woohoo!! I’m a booth babe!)

Some of the planned posts I have include using Heat templates, using Ceilometer, and a new multi-part series on the new “RHEL-OSP Director” that will ship with RHEL-OSP 7.

Don’t be afraid to request blog topics in the comments section. I can’t guarantee that I’ll do it, but if I think enough other readers will benefit and it’s within the niche of this blog I’ll will!

PackStack for RHEL-OSP Revisited

Hi folks,

In today’s post we’re going to revisit our old standby tool, “PackStack”. Why? Because it’s worth remembering that it’s a solid tool to work with, even if it’s not very flexible. As much time as I spent on the RHEL-OSP Installer, what if you just want to stand up 2 or 3 nodes and be done with it? The Installer might be overkill. But then again, what if you want to duplicate what I did regarding the network prep in the Installer with PackStack?

Boom! That’s ~exactly~ what we’re doing today. Continue reading

Custom Cloud Images for OpenStack pt3

Hi folks,

In the last 2 posts we covered creating a custom cloud image for RHEL, then editing it with “guest fish”. Today, I’ll introduce you to another tool called “oz” as we continue our journey into creating custom cloud images. The way we did things last time using “virt-manager” is fine if you’re doing an image here or there.. but let’s face it, walking through anaconda is cumbersome. Granted, I showed you how to do things using the CLI and kickstart, but I think you’ll like this way even better. Continue reading

Custom Cloud Images for OpenStack pt2

In the last post, I essentially kicked off a new multipart series on creating custom cloud images for RHEL, Fedora, and CentOS. I showed you the basics for RHEL, then said I would follow up with Fedora or CentOS. I lied. I decided that I wanted to show you a little fun with “GuestFish” (guestfs, libguestfs) first. It’ll be a quick post with some links to take you further should you want to take things deeper… Continue reading
