Bhyve - EPT/Real Address Mode - Unrestricted Guest

[James Lodge]

Hello all,


Can someone please confirm that having EPT support in the CPU is not necessarily enough to run Bhyve. I have an Intel Xeon L5520 (Nehalem family) that supports EPT but when trying to run an VM, receive


Windows VM UEFI

2 vCPUs requested but only 1 available

ROM boot failed: unrestricted guest capability not available


Linux MV Grub

VM unrestricted guest capability required
Error in initializing VM

My understanding is that the L5520 does not have support for "Unrestricted Guest/Real Address Mode"  which was introduce with the release of the Westmere architecture.


I assume its a non starter without the unrestricted guest feature.


Running FreeBSD 11.0-CURRENT r294227

James
