VMware justed added a new KB article about problems with Storage VMotion script:
Storage VMotion can fail for a virtual machine with the error message:
Failed to unstun VM after disk reparent.
The virtual machine is partially migrated and powered off. Generally, the virtual machine cannot be powered on again.
This issue affects:

Virtual machines converted in-place (not deployed [...]

I noticed at a few customer sites that the Performance tab of VirtualCenter was getting sluggish but never got the chance to really pinpoint the problem. A couple of days ago user “jterpstr” posted about this on the VMTN forum and it seems that the old rows aren’t deleted from the database for some reason. [...]

Today I encountered a weird problem. When I started the installation of VirtualCenter 2.0.2 on a Windows 2000 Server I received the following error notification:”Setup cannot continue. The “VMware VirtualCenter Server 2.0″ requires Update 1 Rollup for Windows 2000 SP4. Please see KB article 816542 at http://support.microsoft.com/kb/816542/.”
I checked the server but the patch was installed, [...]

I was just testing the new, but still experimental feature, Distributed Power Management. I’ve installed 3 ESX Hosts and added all of them into an HA-DRS Cluster. I enabled DPM and set the mode to manual and pressed “Generate recommendations”. I had one host with an HA failure and DPM recommend me to switch off [...]

For those who did not have any luck with the deleting of the dll(ssleay32.dll) described in this blog, there’s another possibility to enable the VMware Converter plugin without crashing your VirtualCenter client:
Go to the following registry key:
[HKEY_CURRENT_USER\Software\VMware\VMware Infrastructure Client\Preferences\UI]
And set the following key to “Enabled”
“C:\\Program Files\\VMware\\Infrastructure\\Virtual Infrastructure Client\\Plugins\\Converter Enterprise\\plugin.dll”

Today I encountered a weird phenomenon which I did not encounter yet. I installed the VMware Converter Plugin for VirtualCenter client, so far so good. Only thing left to do was to tick the checkbox to enable the plugin. But as soon as I ticked it the VirtualCenter client crashed without any warning. I rebooted [...]

Today I encountered a weird error during an implementation of VMware Consolidated Backup. When ever I ran vcbmounter I received the following error:”Run time error - the application the application has requested the Runtime to terminate in an unusual way.”
It seemed that for some reason the vcbuser did not have the role “VMware consolidated backup [...]

A couple of days ago I wrote about the problems with VST and the Intel Quad-port nics. I tested the work around, using “access ports” on the physical switch(EST, external switch tagging) and it seems that the problem is “solved”. A couple of hours ago VMware posted a knowledge base article about this problem, so [...]

This week I implemented a couple of Dell 2950 Servers which contained an Intel quad-port nic. The physical switch ports were setup as a trunk so I used VST(Virtual Switch Tagging). I combined the onboard Broadcom ports with the Intel quad-port nics to have the most redundant setup. When I started testing the HA and [...]

Recently I implemented ESX 3.5 with VirtualCenter 2.5. After I installed the ESX Hosts and the VirtualCenter server the customer told me that I had to change the ip-addresses of the service console. I removed the ESX hosts from the VirtualCenter server, removed the vswif of both hosts with “esxcfg-vswif -d” and created it again [...]
