London VMUG – 14th June 2018

Thursday 14th June saw the latest London VMUG take place at Tech UK, London, with the User Group marking it’s third outing for 2018 in just six months! Rarely does any event see such heavy hitters as Duncan Epping, Frank Denneman, and Niels Hagoort in one place, but today, we got to see all three in attendance. Add to that line-up further awesomeness in the form of  vCommunity member, Chris Porter, and this was one truly great London VMUG indeed! I’ve been to a number of VMUGs around the UK, however, this was to be my first time joining the London gang.

Editing Protected VMs in vSphere

By design, there are certain virtual machines and/or appliances within vSphere which are protected to prevent editing (this can include NSX Controllers, Edges, Logical Routers, etc.) In a live/production environment, you’d not normally care about editing these appliances, however, in a lab environment (especially one where resource is tight), reducing memory and/or CPU allocation can help a lot. As such, this article will cover the process of removing the lock on protected VM in vSphere, in order to enable editing.

The scenario: a customer needs to reduce the resource allocation of an NSX Controller, however, due to the VM in question being protected/locked, editing the VM’s resources is not possible via UI or PowerCLI.

The process of removing this lock is quick and easy, however, we first need to identify the virtual machine’s Managed Object Reference (moRef ID). Please note, VMware do not support or recommend this procedure in any way.  As such, this procedure should not be implemented in a production environment.

VMware vRealize Log Insight: Part 2 – VMware NSX Integration via Content Packs

In Part 1 of this series we covered the simple installation and configuration of VMware vRealize Log Insight. In Part 2 we will cover how we can further configure and customise Log Insight via Content Packs in order to leverage further logging capabilities.

As mentioned in Part 1, one of the caveats of utilising this ‘free’ version of Log Insight (or more aptly, the 25 OSI license available to all vCenter Server licensees), is the ability to use VMware-only Content Packs. This is far from a bad thing and, as a result, enables us to integrate with other VMware products including NSX, Horizon, SRM, etc. In this article we will focus on the former product.

VMware vRealize Log Insight: Part 1 – Install & Configuration

If, like most of us, you forward vCenter and ESXi host Syslog data to centralised Syslog targets (and if you don’t, then I’d advise you do), then you’ll be pleased to hear that (as long as you have a valid vCenter Server license) you’ll be able to utilise the power of VMware vRealize Log Insight to interrogate this data.

This article will be the first in a two part VMware vRealize Log Insight series, the first of which will detail the simple installation and configuration process, with the second article focusing on advanced configuration and integration with VMware NSX via vRealize Log Insight Content Packs (vRealize Log Insight add-ins enabling further integration with both VMware and 3rd party products).

VMware NSX Guides

If you’ve somehow managed to miss these brilliant (and free) VMware NSX guides, then worry not, as here are the links in all their glory. I cannot praise these books enough. Simply brilliant (and free!) Continue reading

VMware vSphere 6.5: Migration from Windows vCenter to vCenter Server Appliance

Following on from my previous posts (What’s New in vSphere 6.5 and VMware VCSA 6.5: Installation & Configuration), a major area for discussion (and excitement) is the VMware Migration Assistant which, should you wish, is able to easily migrate you away from the Windows-based vCenter Server to the Linux-based vCenter Server Appliance (VCSA).

VMware vCNS 5.5.4 to NSX 6.2.5 Upgrade

I’m a fan of upgrades that ‘just work’, but rarely do they run without a few unforeseens jumping out at you. Reading the VMware Upgrading VMware vCNS 5.5.x to NSX 6.2.x (2144620), I was surprised to see just five upgrade areas. Five? Really?? As this is a business critical system (and one with the potential of being able to turn a long day into an even longer day were things to go awry), I was a little sceptical, however, the vCNS to NSX upgrade process really is that easy.

VMware Product Walkthroughs

A great new range of informational overviews is available via the VMware Product Walkthroughs website. Covering a range of product overviews (from vSphere 6.5vRealize Network Insight, and more), to the specifics of vSphere 6.5 Encrypted vMotionNSX VXLAN Configuration, Virtual SAN Fault Domains. Great on so many levels, enabling us to up-skill and dry-run new products, demonstrate solutions to management and technical teams, etc. Continue reading

VMware vSphere: Locked Disks, Snapshot Consolidation Errors, and ‘msg.fileio.lock’

A reoccurring issue this one, and usually due to a failed backup. In my case, this was due to a failure of a Veeam Backup & Replication disk backup job which had, effectively, failed to remove it’s delta disks following a backup run. As a result, a number of virtual machines reported disk consolidation alerts and, due to the locked vmdks, I was unable to consolidate the snapshots or Storage vMotion the VM to a different datastore. A larger and slightly more pressing concern that arose (due to the size and amount of delta disks being held) meant the underlying datastore had blown it’s capacity, taking a number of VMs offline.

So, how do we identify a) the locked file, b) the source of the lock, and c) resolve the locked vmdks and consolidate the disks?

VMware vCenter Server Appliance 6.5: Installation & Configuration

Following the general release of VMware vSphere 6.5 last month (see my What’s New in VMware vSphere 6.5 post), I’ll be covering a number of technical run-throughs already in discussion throughout the virtual infrastructure community.

We’ll be starting with a fresh installation of the new and highly improved vCenter Server Appliance (VCSA), followed by a migration from the Windows-based vCenter Server 6.0; the latter task made all the easier thanks to the vSphere Migration Assistant. More on this to come. Lastly, I’ll be looking at a fresh installation of the Windows-based product, however, the experience throughout all of these installation/migration scenarios has been vastly improved.
