how to use 64bit Redhat on Xeon 3210?

[-Muu-]

I want to use 64bit Redhat4 update6 on PowerEdge840.

Its CPU is Xeon 3210.

I Created guest OS 「Red Hat Enterprise Linux4 (64bit), but Redhat4 64bit installer said "Your CPU does not support long mode. Use a 32bit distribution."

How to solve this problem?

Have you enabled Intel VT in the BIOS? Run esxcfg-info | grep HV at the console to see if that is the case. If it is, then you'll get the output below. Otherwise you'll need to enable it and the cold restart the host.

# esxcfg-info | grep HV

|----HV Support............................................3

I tried that command.

# esxcfg-info | grep HV

|---- HV Support .... 2

So I change value of IntelVT in Bios and Try again, Redhat installer proceeded next step.

Thank you very very much:)
