Vmware guest OS install jam

SteveInTallyFL · 03-06-2009, 10:21 AM

I have an RHEL4u7 (x86_64) server running Vmware Server 2.0.0 build 122589. There is already one virtual server running RHEL4u5 (32-bit). Today I want to add another virtual server as RHEL4u7 (x86_64) - the same as the host operating system. On virtual startup for the guest OS install I immediately get the "Your CPU does not support long mode. Use the 32-bit distribution" error.

Is this a limit of the free Vmware server? Is this because the first virtual server I made was 32-bit? Could I have missed a critical setting during the creation wizard?

I needed to set the VT switch in the BIOS to ON. This allows for mixed OS platform level calls to be handled by the CPU. Once this was set everyting went fine.

Yeah that is right.

I had the same problem on a friend of mine machine´s.
It was a DELL server and the virtualization was switched off by default.

The first VMware machine was 32bit and mine was 64bit and same thing happened to me.
