have a cluster with 06 ESX4, all dell R710 processor (x5660). 03 are with BIOS 2.xx and 03 others are with the last version 3.0.0
After upgrading the bios I noticed that when I do a VMotion vmware bios with an old one with new bios, the problem and complains that the EVC is not enabled.
Two possible causes in my point of view:
1 - He changes masks
2 - Disable ExecuteBit - can be disabled.
Tomorrow I will do some tests, creating new cluster with EVC and so on.
Any ideas? kb?
Welcome to the VMware Communities forums. If you're getting an error like - problem detected at CPUID level 0×80000001 register ‘edx’ - I would suggest checking to see if the no-execute option is disabled on the host. You can also make a VM change for this - http://kb.vmware.com/kb/1001131.

i update bios of servers to bios 3.0 and works fine now. But works fine becausa all hosts need be in same version of bios. I check execute bit but the problem not is here.
the best solution is, stop virtual machines running in host with version of bios out of date, upgrade, and re-add at cluster.
