Last year I installed three Dell PowerEdge 1950 1U servers and since than I used them in production as VMWare Server hosts. Couple times when creating and migrating the guest machines I received a warning that my CPU was VT capable but not enabled. To enable this option reboot the Dell server, hit F2 to enter the BIOS and change the Intel VT Virtualization Technology CPU setting. Each month there is a scheduled maintenance and if there is a security update than it will be installed and server reboot, but than I will need to be there and enter the BIOS by console or DRAC console. For that reason I created two scripts to check the CPU bios setting and if required execute the second cmd script to enable the VT option.

Please make sure the Dell OpenManage software is installed. The commands available for Windows and ESX operating systems.

@echo off
REM Ivan Versluis / Ivan1980(at)networknet.nl / Dell PowerEdge Intel VT enable
omconfig chassis biossetup attribute=cpuvt setting=enabled
omconfig chassis biossetup attribute=dbs setting=enable
pause

For more information check out this document. The enable script has been executed and I only need to get new security updates for this month. I’ve seen no security update information from Microsoft last days and I will need to wait until next WSUS assigned patches will reboot the servers.
