Last year I installed three Dell PowerEdge 1950 servers, these servers were running as VMWare Server virtualization hosts. Couple times when creating and migrating some VM’s a warning was displayed that my processors where not VT capable or this options was not enabled.
To enable this option a reboot was needed, enter the BIOS (F2) and change the Intel VT Virtualization Technology CPU setting. Every month I planned s a scheduled maintenance window to install missing security updated, and I didn’t want to wait for that reboot and manually configure these options from the BIOS. I created two scripts to check the processor specifications and enable the VT option for the processor.
To run the following scripts Dell OpenManage software is required.
@echo off REM Ivan Versluis / www.networknet.nl / Dell PowerEdge Intel VT check omreport chassis biossetup & omreport chassis processors
@echo off REM Ivan Versluis / www.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. I run the enable CMD script on my servers and waited for the scheduled reboot. After the reboot the new settings was applied and I didn’t get the warning from VMWare Server.
