I am currently using VM ESXi 4.1.0 on a Dell PowerEdge R710. It is hosting 3 VMs that are all running Windows Server. I need to install Windows Server 2008 R2 64-bit and in order to do that I have to adjust the BIOS to enable VT so a 64-bit OS can run.
My question is will this change in the BIOS affect the current 32-bit systems running on this server? I need to know if I have to move these Windows Server 2003 to another VM ESXi or if the change will not affect these VMs.
