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.

At work, I'm currently deploying a Windows 2008 R2 on a VMware ESXi 4.0, and noticed an odd behaviour. At irregular intervals, the console of the guest OS simply locks up and doesn't do anything anymore. Networking and remote access seem to work fine, it's just the console that is freezed. Restarting the vSphere client doesn't help, and the only way to get rid of the problem is by hard-resetting the VM. The issue only occurs on Windows 2008 R2, the other VMs run fine.

The problem is caused by the VMware SVGA II driver, and has two underlying issues: the driver itself, and an apparent lack of video RAM (due to the new HW-accelerated GDI of 2008R2/Win7).

The most quickest way is to get rid o  ...

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>
