Updated by tuxillo about 2 months ago

Hello, 

 I tried tryed vkernel64 according to vkernel(7) with & without    machdep.pmap_mmu_optimize.  

 With    machdep.pmap_mmu_optimize=0 vkernel boots with many  
 @ept_copyout: ept_copyout: could not fault in vm map, gpa: 804928000@ 804928000 (addresses are changing) 

 With machdep.pmap_mmu_optimize=1 box paniced (no dump, keyboard hangs --- I can't type anything) 
 <pre> 
 panic: assertion "origpte == 0 || (origpte & pmap->pmap_bit[PG_MANAGED_IDX])
