When updating VMware Tools the setup constantly bailed out without a decent error. So I decided to un-install the Tools and install them again. Un-installing went smooth but when installing it again I ended up with the error “internal error 2203″. After googling this error the Citrix website gave me the solution, check your tmp and temp environment variables. Indeed [...]

Today I received the following error at a customer site when applying patch via the Update Manager:”Metadata for patch missing.” After a close inspection I noticed VirtualCenter wasn’t running on port 80 but on 81 for some reason. Opening up the ESX Firewall and restarting the VMware Update Manager service seems to fix this problem. The firewall was opened up [...]

Today I noticed the following in a ESX 3.5 and Virtual Center 2.5 environment: When you check the performance of the memory(past day) on the cluster the minimum and maximum is way more than expected. In this case the minimum is 66,9% and the maximum 106,01%. This cluster has around 64GB of memory and there’s only around 30GB assigned, nowhere [...]

Today I visited a customer with the same setup, Dell servers and an EMC SAN and I was curious if I could reproduce this error. Well I did not had not much trouble reproducing the error because they already had the same issue. I [...]

Even if the LSI could go higher than 32 it would be capped by either the device queue depth or disk.schednumreqoutstanding. To enable a single VM to have a queuedepth larger than 32 [...]

Vinternals wrote a short article on how to de-install or hide the Capacity Planner plugin for VirtualCenter: Capacity planner is rather pesky to have hanging around on every VirtualCenter box in the enterprise… especially if you use some other tool for the job! So just add this line to the end of your VirtualCenter install script: msiexec /qn /x {2A2750C9-E14E-4635-8595-C1CD214445B0} [...]

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. The table grows to an [...]
