You can use the Guided Search Wizard for VMWare Compatibility Matrix to figure out if a certain version of ESX or feature is supported by a certain server or hardware platform:
Shutdown the VM.
Open .vmx file with Notepad or another plain text editor.
Add these lines:
hypervisor.cpuid.v0 = "FALSE" mce.enable = "TRUE" vhv.enable = "TRUE" vpmc.enable = "TRUE"
Save and start the VM. Now you can install the Hyper-V role.
Before installing ROK licenses on your virtual machines on VMware, be sure to allow SMBios reflection of the host to the VM's. Otherwise, authorization will fail with a This system is unsupported message.
To do this, go to the settings of your newly created VM. Click the tab Configuration, then click General, then the button Configuration Parameters. Add a new row:
SMBIOS.reflectHost = TRUE
If you're running RDS on a vSphere server with VMware Tools installed, you may wish to remove/hide the system tray icon. This can be done by setting a certain registry value.
The registry value is:
Change the value to 0 will effectively disable the icon the next time a user logs on.
In VMware ESXi 4.1, by default, the video drivers are not correctly installed. This is because of the fact that the old driver (which is installed by default) is a WDM type of driver. This type of driver has been kicked out of Windows 7 and Windows 2008R2 in favour of the newer WDDM driver architecture. As a result, the video is reverted to the Standard VGA adapter, which has terrible performance.
However, installing the VMware Tools does provide a correct driver, even though it is not installed by default. To install it, see the second chapter of the article: Windows 2008 R2 console freezes in vSphere console.
It is not possible to convert disk files from thick to thin, in-place. Instead, cloning the disk (or machine) allows you to change the provisioning type and thus enabling to have a thin disk. After the clone is complete, delete the original and you're good to go.
You can either clone a complete machine, or just clone a disk using the CLI or service console:
vmkfstools -i <srcDisk.vmdk> -d thin <dstDisk.vmdk>
