Very slow shutdown VMware Workstation guests

Check out the link below if you encounter slow shutdowns of VMware Workstation guests:

In my case it reduced the shutdown time of Guest OS (on VMware Workstation 9.0) from several minutes to less then 30 seconds.

In a nutshelf:
Close VMware Workstation and add the text below to config.ini

prefvmx.minVmMemPct = "100"
mainMem.useNamedFile = "FALSE"
mainMem.partialLazySave = "FALSE"
mainMem.partialLazyRestore = "FALSE"

VMware Workstation message: This CPU is VT-capable, but VT is not enabled

On a HP Compaq 6710b with Vista 64 bit installed and VMware Workstation 6.0.5, when launching the installation of Windows Server 2008 x64 (as Guest OS), the following message was displayed:

This CPU is VT-capable, but VT is not evabled (check your BIOS/firmware settings). You have configured this virtual machine to use a 64-bit guest operation system. However, this host’s CPU is not capable of running 64-bit virtual machines or this virtual machine has 64-bit support disabled.

For more detailed information, see http://www.vmware.com/info?id=152

Pretty straightforward how to solve this one, given the information above: enter the BIOS settings –>

System Configuration > Device Configuration > Virtualization Technology > Enable.

After booting the same message appeared. After another reboot, the message did not appear anymore.
