Re: How to unload the vmm.ko module while FreeBSD is running...

ok. I've been able to unload vmm :

[root@marietto /dev/vmm]==> bhyvectl --vm=vm0:12 --destroy

[root@marietto /dev/vmm]==> cd /dev/vmm
cd: no such file or directory: /dev/vmm

[root@marietto /dev/vmm]==> kldunload vmm
OK.

but now I would like to load it again :

[root@marietto /dev/vmm]==> kldload vmm
kldload: can't load vmm: module already loaded or in kernel

[root@marietto /dev/vmm]==> kldstat | grep vmm

[root@marietto /dev/vmm]==> ls /dev/vmm
ls: /dev/vmm: No such file or directory
