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 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 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.

Integrating Active Directory with VMware vSphere SSO

One item I see mentioned fairly often, either in relation to personal labs or production environments, is the integration of vSphere SSO with Active Directory. Configuring vSphere’s SSO/AD integration via LDAP is a simple process, more so thanks to vSphere 6.5. Continue reading
