Author: grehan Date: Sun Nov 23 23:07:21 2014 New Revision: 274931 URL: https://svnweb.freebsd.org/changeset/base/274931
Log: Change the lower bound for guest vmspace allocation to 0 instead of using the VM_MIN_ADDRESS constant. HardenedBSD redefines VM_MIN_ADDRESS to be 64K, which results in bhyve VM startup failing. Guest memory is always assumed to start at 0 so use the absolute value instead.
