Enabling Intel VT-Mode in BIOS

[sirbarret]

Hi!

Is it possible to enable Intel VT-Mode after that i installed ESX on the server.

Or will the esx host dont boot up?

May there be other problem?

No problem at all, you can enable it without any issues or strings attached.

Help please !!!

I'm dealing with enable VT-x in my ESXi U1 box.

I've enabled the VT-X mode in BIOS and my CPU is a Intel Core 2 QUAD Q9550.

But booting a VM with the CPU Compatibility Tool (cf. cpuid.iso) the output report :

Supports 64-bit Longmode : Yes

Supports 64-bit VMware : No

What's wrong ?

We do not virtualize VT-x, so a VM will always report "Supports 64-bit VMware: No." If you want to know if your host supports 64-bit VMs, you need to boot the physical machine from a CD that you've burned from that ISO.
