When enabling replay.supported on the vESX this DOES get reset to ‘false’ when the nested ESX boots.

Yes, I made the .vnx changes and enabled AMD-V. The weird thing is that the physical ESX host says that FT is supported but the vESX hosts say not. It looks like something is being filtered out as you go from pESX to vESX.

I make the changes to the .VMX file but as soon as I power on the vESX server it changes to replay.supported = FALSE. The underlying host has FT capable hardware (the summary tab says it’s fine, Intel Xeon 5440) but the vESX host says the CPU isn’t compatible. I’ve tried both vESX and vESXi with the same outcome. If time permits I’ll try vESX4 instead of v4.1 in case that’s any better. Shame, looks like a useful lab setting.

do you have AMD-V enabled in the BIOS

Try as I might, I can’t get FT to work. When I go to the Summary tab of the esxi 4.1 VM and click on the callout beside “Host Configured for FT:” it says “Host CPU does not support hardware virtualisation which is required for FT”. Everything else works – HA, vMotion, DRS, nested VMs. Any ideas?

Do you have any idea to block the changes that it makes?

I have a two cpu machine with Intel Xeon E5506.

Thanks in advance,
Miguel
