We've been having fits with getting Windows 2998 server R2 to run in our vSphere environment. We keep getting an error when we attempt to install Win 2k8 R2 - incompatible CPU's.
Having done some research, we found that we needed to enable VT in the host's bios. So we made sure all of our hosts had it enabled (and that actually made it so we could use enhanced vmotion...).
We still receive the error when attempting to install Win 2k8. So in my research I found a utility to create a boot CD that you can put in the host and get some information regarding the CPU's and their compatibility with 64-bit. I ran this on one of our hosts and got a message that says:
"VT is not supported on this system due to an inconsistent mix of VT features on different processors."
Also in the log we found that the CPU brand strings indicate:
-intel Xeon cpu e5310.. on bin 1 and
-intel Xeon cpu L5310.. on bin 2
Also, it indcates the following for each bin:
bin1: family: 06 model: of stepping 7
bin2: family: 06 model: of stepping b
We had 3 hosts each with 1 cpu (quad core) and later upgraded them to 2 cpus (quad core). We've had no problems running things (except enhanced vmotion would enable turns out VT wasn't enabled on one host). but we're supposing that something in the stepping of the CPU's is the issue, but all searches for the "VT is not supported on this system..." message have resulted in NO results I'm wondering if anyone can shed some light on this situation for us.
Any help would be greatly appreciated.
