Hi Peter, Thank you for the clarification. It looks like I'll need to purchase a couple to Westmere X5650 CPU's that do have the 'unregistered guest' feature as I need to be able to running multi vcpu FreeBSD vms and Windows. Thank you again for your help.

Hi James, 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 ... 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. Yes, that's correct. I assume its a non starter without the unrestricted guest feature. Mostly. You'll only be able to run single vCPU FreeBSD guests since they boot directly into 64-bit mode: everything else (including multiple vCPU guests) requires either 16-bit support or 32-bit non-paged protected mode, both of which are only available on Intel with the 'unrestricted guest' feature. later, Peter. ___ freebsd-virtualization@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"
Bhyve - EPT/Real Address Mode - Unrestricted Guest
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.
