In my case it had something to do with the Drac-configuration. I had to disable “System Services” in the drac-menu.

The weird thing was, that i have 2 identical servers, and only one of them had them problem.

Know your way around in the vCenter GUI. There are some questions in the VCP4-test regarding what options you have different places in the GUI. Go through all menus and options, and know what they are there for.

An example could be: What is the default setting for “Default cluster settings” under VM monitoring in the HA-configuration?

1: Low

2: Medium

3: High

Check out this blog post from Jeroen van de Kamp. Alot of thing to consider when virtualizing TS/citrix workloads. Also handy in a VDI-environment.

Check out this forum post. Alot of usefull things and considerations.

First of all, know your maximums! Its not that big a part of the test but its is easy point if you can memorize them. Memorize this whitepaper and take the the practice exams that on Simon Long’s blog until you get them 100% right. That helped me alot.

I passed my VCP4 today :) Pretty difficult test.

I would like to introduce feedreader. Its a regular rss-reader, nothing fancy there. I use it every day to get news about different things and i would like to share the virtualization-rss-feeds i use and read.

Power issues ;)

I am gonna upgrade out ESX4-hosts to u1 and i came across this problem. One of the VMs would not vmotion to another host. I am getting this error

“Migrate virtual machine ubuntu02.domain.tld The operation is not allowed in the current state.”

The thing that was wierd was, that it was only that VM that had the problem. The CPU and memory-usage counter showed 0. So i tried reinstalling vmware tools and reboot. Nothing helped.

I found the solution here

service mgmt-vmware restart

and

service vmware-vpxa restart

solved the problem
