https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D217885 --- Comment #16 from Nathan Benson <online@nahlem.com> --- So after more research and talking with the FreeNAS guys it suddenly clicked for me.=20 To work properly you need VT-x with EPT to be able to use unrestricted gues= ts. Great, dmesg clearly shows that for me: VT-x: PAT,HLT,MTF,PAUSE,EPT,VPID However, someone posted theirs and it looked like this: VT-x: PAT,HLT,MTF,PAUSE,EPT,UG,VPID It finally dawned on me the UG flag stands for "Unrestricted Guest". So, hopefully this will help everyone else in the same situation as we were, being, Intel specs said we have VT-x and EPT (as did FreeBSD), but the CPU flags didn't have UG.=20 Upon more investigation it appears that UG came about in the Westmere and l= ater processors. Mine was Bloomfield, the architecture just previous. So, I boug= ht an Intel i7 860x which should have UG support.=20 Many thanks guys and hopefully this will help clear up the issue for others= and give a more clear answer as to why in the future. --=20 You are receiving this mail because: You are the assignee for the bug.=
