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 “Custom Cloud Images for OpenStack pt2”
We previously finished our multi-part series on deploying RHEL-OSP with the RHEL-OSP-Installer. In a few weeks, if all goes according to plan I’ll fire up a new series on the next gen installer… In the mean time, I’d like to show you some useful things to do once you’ve got everything up and running. So what’s up first? Well, as the title suggests, we’re going to create some custom images.
Specifically for RHEL, Fedora, and CentOS. Our new and current multi-part series… Continue reading “Custom Cloud Images for OpenStack pt1”
I’m starting a new multi-part series on deploying the OpenStack Installer from Red Hat. Hopefully, this makes some folks very happy.. Undoubtedly, this makes others confused, and still others wonder what the big deal is.
Here’s the short answer as to why I’m headed in this particular direction: It’s a strategic, albeit temporary, direction for Red Hat. Continue reading “OpenStack Installer (for RHEL-OSP) pt1”
I hope to make this a “many part series”, broken up over time, but not every post… if that makes sense. What started this was that while I have access to some labs at work, they aren’t always available and they aren’t always conducive to me blowing them up. (I like to break things… then fix them, it’s how I learn.) Because of this, I bought some gear to hammer away on to test new things on RHEL 7, KVM, OpenStack, etc… but I’m not independently wealthy either, so I’m going to make due with what I have for some pieces… Continue reading “Lab on a Budget Tricks – pt1”
Once again, I’m behind in posting and once again Red Hat Summit is upon us!! The truth is that I’m behind in writing not because there isn’t anything to write about, but because there has been so much going on – including Summit! Continue reading “See you at Red Hat Summit!”
Hi folks, today’s post will cover something that came up in the last few days at work. Someone was concerned about any lengthy delay affecting the health of his VM’s virtual disk and therefore the VM. We’ve all seen the aftermath – either the VM falls into a “paused” state, or the disk goes into a read-only state. So, how do you extend the timeout value in KVM for SCSI disks? Continue reading “Extending SCSI Timeouts in KVM Guests”
I have some updates on my Red Hat Summit session that I’d like to share. This will be my 3rd year in a row that I’ve presented, and I’m bringing friends from both NetApp and Red Hat to discuss “Scaling Out Tier-1 Applications with Red Hat Enterprise Virtualization & Clustered ONTAP”.
So what exactly does that mean? Continue reading “Update to Red Hat Summit session”
Hi folks, in today’s post I’d like to cover something fairly elementary – providing HA for the RHEV-M application. To be honest, I can’t believe I haven’t written a post on it sooner. If you have power users, VDI users, and/or other services (via API/SDK) that depend on RHEV-M, it’s definitely critical. Besides, providing HA for RHEV-M is just downright convenient, even if it’s just virtualization administrators that need access. Continue reading “Providing High Availability for RHEV-M”
My last post was about creating channel bonds, virtual bridges, and VLANs in order to make the best use of 10GbE. This time around, we’re going to apply the same logic and planning to a Red Hat Enterprise Virtualization (v3.1 if you’re interested) environment.
Hi folks, it’s been a few weeks since I posted anything. It’s been busy for me as I’m in the middle of the biggest project that I’ve ever lead. It’s got huge implications, and while I’ve dropped some not so vague hints, I want to show you one tiny aspect of it today:
Effective use of 10GbE using VLANs and Channel Bonding
