https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=288237 --- Comment #15 from Konstantin Belousov <kib@FreeBSD.org> --- (In reply to Zhenlei Huang from comment #13) Any exception can be programmed to either cause VM exit or to be reflected directly into the VM. For Intel VMX, see vol.3 26.6.3 Exception Bitmap. By default, bhyve only sets the bit for the machine check exception in the bitmask, so all exceptions except #MC do not cause VM exits. Apparently there is a tunable hw.vmm.trace_guest_exceptions which can be used to do VM exit on all exceptions but then reflect them back (I never tried it). In any case, even if #UD would be passed through VM exit, bhyve does not even try to emulate not implemented instructions. -- You are receiving this mail because: You are the assignee for the bug.
