Z77 / Ivy Bridge System only booting in safe mode

I know it isn't necessary but it can help to speed up virtual hardware in some cases. Managing some Linux systems with server virtualisation I got some experience over the years ...

So do I, I use ESXi at work everyday. I did some testing with VMware Fusion and Parallels Desktop on my hack with VT-d enabled and disabled, there was no difference in performance. I don't think they use VT-d, just VT-x, and that should be enabled in UEFI/BIOS.

Here is a quote from VMware, I guess VT-d is not needed after all.


"When a VMware product says that VT is disabled, it is referring to "Intel Virtualization Technology," otherwise known as VT-x. Some firmware menus offer a separate setting for "VT-d," which is "Intel Virtualization Technology for Directed I/O." Note that it is not sufficient to enable "VT-d." You must enable "Intel Virtualization Technology." Moreover, the only VMware product that uses VT-d is ESX(i). For other VMware products, the VT-d setting is irrelevant."
