From ef7f753c0456a32eb1092ed1a5ee0affd7659c57 Mon Sep 17 00:00:00 2001 From: royger Date: Fri, 21 Aug 2015 15:53:08 +0000 Subject: xen: allow disabling PV disks and nics Introduce two new loader tunnables that can be used to disable PV disks and PV nics at boot time. They default to 0 and should be set to 1 (or any number different than 0) in order to disable the PV devices: hw.xen.disable_pv_disks=1 hw.xen.disable_pv_nics=1 In /boot/loader.conf will disable both PV disks and nics.
