VMotion CPU Incompatiblity

[nicolaj]

Hi,

I'm upgrading from ESX 2.5.4 to ESX 3.0.2. I've already upgraded my VC server to 2.0.1, and I'm now attempting to vmotion virtual machines off one of my ESX servers so that I can upgrade it. I get the following error: "The cpu of the host is incompatible with the CPU feature requirements of the virtual machine. CPUID level 0x1 register 'ecx'"

I'm going from an IBM x366 Intel Xeon MP to an IBM x365 Intel Xeon MP. I've vmotioned between these machines for years in the past using VC 1.4 without ever having a problem, so I'm not too worried about actual incompatibilities. I've found lots of topics in the forums addressing this problem, and the solution is to set the bit mask so VC will ignore the differences. This is not an option on the VM level with ESX 2.5.4, so I have to update vpxd.cfg on virtual center. My question is, what exactly are the differences? How do I code this mask? Here's what's in /proc/vmware/cpuinfo on each of these servers:
