Anyone using openzfs and tuntaposx and VirtualBox

Postby chunlinyao » Thu Sep 28, 2017 6:54 am

Is there anyone using openzfs and tuntaposx and virtualbox on macOS.

When I installed openzfs and tuntaposx, Install Virtualbox will report an error, but all file has installed, the error is because virtualbox can not load the kext. After reboot I can use virtualbox, but I can not access any samba share from mac host. Remove any of the 3 product and reboot will fix the problem.

If there's some openzfs user, would you like to try install tuntaposx and VirtualBox. I don't known if the problem only affect me.
Is it possible that kexts from these 2 product have some conflicts?

If you use "kextstat", you can see if all 3 modules are loaded, and if one is missing, you can try to load it yourself with kextload $path, and for more verbose information, kextutil $path

There could be a chance that we all define a symbol name, so it can not load due to multiple definitions.

Confirmed with `sudo kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}'`
With openzfs and tuntaposx loaded, I can not load any VirtualBox kexts.

Finally I keep the openzfs(spl.kext, zfs.kext) and tap.kext, removed tun.kext. And modified the virtualbox startup script to not load VBoxNetAdp.kext.
Every things works. I can run vm guests and access samba shares from my macos host.

Some one mentioned there's free device slot limit in macos. It seems this is the cause. see the following links.

That is interesting. We should only be using 1 slot, if that is indeed the case. Perhaps there is a boot-args switch to increase the setting?
