VMware vSphere 5.5 Update 1 NFS disconnects

A new issue has been discovered with vSphere 5.5 Update 1 that is related to loss of connection of NFS based datastores. The result is an All Paths Down (APD) of the NFS datastores meaning that vSphere loses connection to the virtual machine files and/or the virtual machines will not be able to do any IO to the datastore. This will result in a BSOD for Windows virtual machine and read-only filesystems for Linux guests. Last friday we encountered this ourselves and already got the confirmation from VMware Support that this was indeed a bug but the information was confidential. Now […]

VMware Horizon View graphics – vSGA vs vDGA

As VDI solutions become more and more mainstream for standard office environments, a new challenge appears. We can swap the bulky desktop and replace it with a small thin client, delivering Windows desktops from the datacenter. Enabling a more flexible way of working with free seating, working at home. But how about those ‘special’ users who always get a ‘special’ workstation with high end graphic cards, dual monitor setup working with AutoCAD, Bentley MicroStation, etc? Can we deliver the high end graphics needed for these applications to a VDI desktop also enabling the VDI benefits for these users? I’ve been […]

How to delete an orphaned desktop pool

Time for a new problem in the VMware Horizon View series. After running into problems which forced me to ‘Manually delete protected Horizon View replicas‘ and ‘Link a VMware View desktop to its replica‘, now I encountered an orphaned desktop pool which could not be deleted. First, What got me into this mess. As I told you last week I was testing a Nvidia Quadro K5000 graphics card when my ESXi whitebox died on me. This also corrupted the one hard drive which contained all my Horizon View desktops. Fortunately the golden images resided on my NFS storage so no […]

No internet connection results in slow vSphere client consoles

In the last few weeks a customer that I am working for has been making a lot of changes within their infrastructure. Some big and some (on the surface) small. Somewhere during those weeks a change was made and the consequence of that change has gone by unnoticed at first. Then reports started to come in from colleague administrators that console sessions for virtual machines, when using the vSphere client, where really slooooowwwww. Opening a console took more than 10 seconds and trying to open more simultaneous would freeze the users screen entirely.

Building a new ESXi whitebox

Unfortunately the whitebox ESXi server I build in June 2011 died on me when testing a Nvidia Quadro K5000 graphics card. So I needed a new ESXi server for my home lab. I looked at some HP and Dell mini servers but  I decided to build a new VMware ESXi whitebox. Power supply, hard disks and SSD were still fine so I only needed a new motherboard, processor and memory. In the past I’ve used websites like, ‘Ultimate VMware ESX Whitebox‘ and ‘VM-help.com‘ to find compatible parts but because one no longer exists and the other is pretty outdated I […]
