Jumpy mouse and video in windows 2008 R2 VM

Finally fixed the issues I've had with vmrc and vi client video in a windows 2008 R2 VM. You need to change the video driver ANd the mouse driver.
1) install the latest tools
2) change the display device driver to the one in c:\prorgram files\common files\vmware\drivers\video (use wddm_video, that's the best).
3) change the mouse driver by clicking  "let me choose..." and selecting VMware pointing device.
4) change the video ram to more than 8 mb (optional)
It's amazing that vSphere doesn't just install those for you.

vCenter in a VM - VMware encourages it

For those still wondering whether or not to install vCenter in a VM instead of physical hardware, here's the advice from VMware. This comes from the installation documentation, which is the canonical source in my mind.

Install vCenter Server in a Virtual Machine

You can install vCenter Server in a Microsoft Windows virtual machine, which runs on an ESX host.

Deploying the vCenter Server system in the virtual machine has the following advantages:

  •  Rather than dedicating a separate server to the vCenter Server system, you can place it in a virtual machine running on the same ESX host where your other virtual machines run.
  • You can provide high availability for the vCenter Server system by using VMware HA.
  • You can migrate the virtual machine containing the vCenter Server system from one host to another, enabling maintenance and other activities.
  • You can create snapshots of the vCenter Server virtual machine and use them for backups, archiving, and so on
