Changing vCenter Operations Manager vApp IP Addresses

by

I needed to renumber one of my VMware vCenter Operations Manager 5.6 instances and it’s not immediately clear how to do it. It isn’t like the other virtual appliances VMware delivers. Here’s how I got it done, with some encouragement from Matt H. in VMware Support. It also seems to me someone wrote this up recently, but I could not find it. If that was you please leave me a comment with a link to your work. 1. Shut it all down. Take a snapshot of the individual VMs. I ended up having to revert to the snapshot, so that was nice. Remember that if you revert it reverts the VM config, too. 2. Edit the properties of the vC …

VMware vSphere, LLDP, and Juniper EX Switches

by

One of the vSphere environments I support uses Juniper EX4200 switches for networking. Juniper switches don’t support Cisco Discovery Protocol (CDP). I love CDP because I can tell exactly what switch & port I’m attached to, and see other information like VLANs, etc. CDP removes a lot of human error from our operations, too. I love it for situations like when two cables are mysteriously labeled as heading to the same switch port or I’m sitting at my desk and I need to refer to a physical port 200 miles north of me. It also means that I don’t need to maintain a document of the switch ports, I can script a dump of the information if I need an …

OpenStack Isn’t Our Savior from Lock-In or Support Costs

by

There is an attitude among some now that OpenStack is, or at least will be, our savior from vendor lock-in in the Infrastructure-as-a-Service cloud space, as well as something that will help corporations save a lot of money in licensing fees from VMware. While I see the potential I think there’s more to the picture. To start with, OpenStack will lock you in just the same as a commercial offering, even though it’ll be “open.” If you want to move from OpenStack to another solution to another there will still be a bunch of hassle to move virtual machines and applications, just the same as if you wanted to move between VMware and Hyper-V, or to a public cloud offering. OpenStack …

Four Things VMware Engineering Can Give Me For Christmas

by

I hope everybody out there in the virtualization world is having a great holiday season this year! My religion celebrates Christmas, and these are four things I’d love to see under my Christmas tree this year. 1. IPv6 support at all levels of the VMware stack. For a cloud vendor that fancies themselves as forward-looking, not to mention trying to be the “VMware of Networking,” the lack of IPv6 is pretty embarrassing. I know, I know, the tired argument is that nobody is really looking at IPv6. Well, it’s hard to look at when your vendor doesn’t support it much. 🙂 Chicken, meet egg. This would also help ameliorate the fact that VMware products need an awful lot of IPs …

VMmark 2.5

by

Oooh, a new version of VMmark is out. From Bruce Herndon on the VROOM! blog: I am pleased to announce the release of VMmark 2.5, the latest edition of VMware’s multi-host consolidation benchmark. The most notable change in VMmark 2.5 is the addition of optional power measurements for servers and servers plus storage. This capability will assist IT architects who wish to consider trade-offs in performance and power consumption when designing datacenters or evaluating new and emerging technologies, such as flash-based storage. A long time ago I was pretty skeptical of yet-another-benchmark, but it’s been useful to help compare physical hosts with virtual workloads. Unlike most benchmarks, the results from previous versions are still relevant to the new version. I …

Tags in VMware vSphere 5.1

by

Mike Preston has a short post & video about the tag features in VMware vSphere 5.1: Just think, say you have hundreds, or thousands of VMs.  You can now more align the way you categorize things inside of your business within vCenter, and sort/search on those custom tags. From the moment I saw the tag features I’ve been pretty optimistic about them. They’d be useful for tagging VMs with all sorts of information, like billing, locations, tiering, or even as a makeshift CMDB by tagging admins, applications, etc. It also wouldn’t surprise me if they were eventually used to drive features like various storage and network profiles, replication, etc. Just set the right tag and everything just takes care of …

VMworld US 2012: Day One

by

Day one was a weird day, roaming the city before the Solutions Exchange “Welcome Reception.” Was trying for breakfast at The Pork Store on Haight but ended up at Squat & Gobble, which was excellent. If you get time to go over there the Crab Cakes Florentine is tasty (that’s the plate photo below). Afterwards we walked down to the Ferry Terminal at the end of Market St. If you haven’t been in that building there are some great food vendors in there. There was also an America’s Cup boat heading down the bay. v0dgeball was successful, though I didn’t attend, instead getting an update from Mark Vaughn who was one of the referees. My understanding is that the Arista …

Tips for VMworld US 2012 & San Francisco

by

As VMworld US 2012 approaches rapidly I’ve been thinking about the things I like to do in San Francisco, and the useful things I have learned over the years. If you have thoughts here about things that I’ve missed or are wrong about please add them in the comments! Transportation: From SFO I usually take the Bay Area Rapid Transit, or BART, to the Powell St. station. It’s cheap at $8.25 a person and relatively fast, though you’ll have to hoof it from the station to your hotel then. If you have more than one person a cab might be okay, but expect the ride to cost $50-$60. Shuttles are also a cost-effective way to travel, $17ish from SFO to …

3 Reasons These VMware vTax & Licensing Rumors Are Great

by

“What is the difference between a taxidermist and a tax collector? The taxidermist takes only your skin.” – Mark Twain I have to say that, if they’re true, I’ve got three reasons to be happy about the VMware licensing rumors that CRN is leaking. First, you may remember from the vSphere 5 launch that I was one of the folks pointing out that due to the fact that you can pool your vRAM licensing it was likely to have little effect in the short term, and shouldn’t stop anybody from upgrading to vSphere 5. The pain would come in the medium-term for folks that practice the “fewer, bigger machines” approach to virtualization (a practice I promote). Thirteen months is definitely “medium-term” …

VMware Engineering, Are You Fixing Anything?

by

I was just reading Josh Andrews’ account of a serious bug still present in the latest releases of VMware vCenter 5.0 (5.0b): This bug has been known for a while and while U1 contained some mentions about fixing it – we now have U1b and the problem still exists…. Make sure you have a cluster with HA and/or DRS turned on…. Enable VM Storage Profiles… Now return to your cluster summary to verify HA and DRS have been turned off and all settings have been lost. This is epic bad stuff here, because if there’s one good way to mess a lot of things up it’s to disable DRS. Especially if you have a vCloud Director setup, since if you shut DRS off …
