Well, that was really just a side effect of my change; my real motivation w= as to make bhyve avoid opening /dev/kmem and /dev/io. I think what I'll do for this case is add a new jail flag, allow.vmm.ppt, to allow admins to explicitly opt-in. ppt requires, among other things, the ability to reset devices, and PRIV_DRIVER checks are used to prevent this f= rom userspace, even if /dev/devctl2 is passed into the jail. In particular it should be possible to run VMs in a jail without giving access to these ppt ioctls. --=20 You are receiving this mail because: You are the assignee for the bug.=
