--- Comment #21 from Konstantin Belousov <[email protected]> --- (In reply to John Baldwin from comment #19) Sure it is not obvious functionality, but in theory vmm can intercept #UD, parse the faulting instruction, and calculate the set it belongs to. If this set is not supported by host or turned off for the guest, vmm can issue a diagnostic. The amount of work and maintenance efforts needed for such functionality is enormous for very specific use case. But it is doable, and really not that complicated. -- You are receiving this mail because: You are the assignee for the bug.
