.Sh NAME
.Nm bhyveload
.Nd load a
.Fx
guest inside a bhyve virtual machine
.Sh SYNOPSIS
.Nm
Simplify the assignment of memory to virtual machines by requiring a single command line option "-m <memsize in MB>" to specify the memory size. Prior to this change the user needed to explicitly specify the amount of memory allocated below 4G (-m <lowmem>) and the amount above 4G (-M <highmem>). The "-M" option is no longer supported by 'bhyveload' and 'bhyve'. The start of the PCI hole is fixed at 3GB and cannot be directly changed using command line options. However it is still possible to change this in special circumstances via the 'vm_set_lowmem_limit()' API provided by libvmmapi.
