Kernel Panic on Mac host when doing file operations on shared NFS drives

[logan-ncc]

Virtualbox causes a kernel panic on Mac OSX Sierra host when doing file operations on a shared NFS folder. There are many things that can trigger the panic, but deleting files is the easiest to reproduce.

Steps to reproduce:

# create a new folder
mkdir vagrant; cd vagrant
# copy both the attached vagrant box image (freebds-10.3-amd64-virtualbox.box) and the vagrantfile into this folder

# add the box to vagrant (this is the easiest way to reproducibly set up a vm)
vagrant box add freebsd-10.3-amd64-virtualbox.box --name local/freebsd
# provision the virtual machine (this will take a while)
vagrant up

# ssh into the virtual machine
vagrant ssh
# we have mounted a shared folder at /vagrant
cd /vagrant
# we need to perform file operations, and the most reproducible way I've found to do this is by creating and destroying a virtualenv
virtualenv venv
rm -rf venv  # this should crash the host

Could not upload freebsd image because of the filesize restriction. It can be found here ​https://www.dropbox.com/s/0uznmn19tvxcndt/freebsd-10.3-amd64-virtualbox.box?dl=0

This appears to be an issue with the mac NFS filesystem and has nothing to do with virtualbox.

Do you have any references for that?
