I have this good old Dell 1850, with Irwindale processors capable of 64-bit. I have installed ESX 3.0.2 on it, no problems, and 32-bit OSes (Win2k3) no problems, but i can't get RHEL5 64-bit to install. Well, I can't migrate an instance to it. Get the error message "Unable to migrate from to . The CPU of the host is incompatible with the CPU feature requirements of the virtual machine; problem detected at CUPID level 0x8000001 registed 'edx'."
Server1 is a Dell 2900 with Xeon quad-core Cloverton, Server2 is a Dell 1850 with Xeon dual-core Irwindale.
Any thoughts or suggestions as to why?
thx
Bill
