[-- Attachment #1 --] Hello. I'm trying to unload the vmm kernel module,but it fails : [root@marietto /bhyve]==> kldunload -fv vmm Unloading vmm.ko, id=13 kldunload: can't unload file: Device busy I don't understand why it fails,since I don't have any bhyve vm currently running : [root@marietto /bhyve]==> ps ax | grep bhyve 6645 4 RL+ 0:00,00 grep bhyve (ggrep) and yes,the vmm module is loaded in memory : root@marietto /bhyve]==> kldstat | grep vmm 13 1 0xffffffff827ac000 37c9e8 vmm.ko how has it been loaded inside the memory ? Using /boot/loader.conf : vmm_load="YES" and it is located inside the directory /boot/kernel and it is called vmm.ko Is there a way to unload it and reload it while FreeBSD is running,without rebooting the system ? thanks. -- Mario.
