Hel= lo.

I'm trying to unload the vmm kernel module= ,but it fails :

[root@marietto /bhyve]=3D=3D&g= t; kldunload -fv vmm
Unloading vmm.ko, id=3D13
kldunload: can&= #39;t unload file: Device busy

I don't underst= and why it fails,since I don't have any bhyve vm currently running :

[root@marietto /bhyve]=3D=3D> ps ax | grep bh= yve
6645 =C2=A04 =C2=A0RL+ =C2=A0 =C2=A0 0:00,00 grep bhyve (ggrep)

and yes,the vmm module is loaded in memory :

root@marietto /bhyve]=3D=3D> kldstat | grep vmm
13 = =C2=A0 =C2=A01 0xffffffff827ac000 =C2=A0 37c9e8 vmm.ko

= how has it been loaded inside the memory ? Using /boot/loader.conf :

vmm_load=3D"YES"

= and it is located inside the directory /boot/kernel and it is called vmm.ko= 

bhyvectl --destroy --=
vm=3D<name>

=C2=A0<= /div>

Is= there a way to unload it and reload it while FreeBSD is running,without re= booting the system ? thanks.
