I'm running on an Acer laptop, and unfortunately it seems (I understand after an exchange of e-mails with their exiguous support*) that Acer saw fit to disable VT-x in the BIOS and not provide an option to enable it. As far as I am aware this means that in order to enable this feature which the CPU does support, someone would have to reverse engineer the BIOS and prevent it from setting a single "lock-bit" with a WRMSR instruction.
Does this mean it is impossible to run a 64 bit guest without said BIOS hack? I seem to be experiencing a significant performance penalty running Ubuntu 32-bit under Vista 64-bit.
Thanks for any information.
