I have managed to boot a VM. The 4GB thing is hardcoded in the vmrun.sh script: 110 echo "Launching virtual machine \"$vmname\" with ${lowmem}MB memory below 4GB and ${highmem}MB memory above 4GB ..." Also, it seems it's hardcoded in bhyveload.c: if (highmem != 0) { error = vm_setup_memory(ctx, 4 * GB, highmem, NULL); <--- here if (error) { perror("vm_setup_memory(highmem)"); exit(1); } } I used './vmrun.sh -m 512 -M 0 vm1' which sets highmem == 0 to avoid this call.
