Vagrant-ZFS is a plugin for Vagrant to automate cloning and sharing ZFS filesystems from the host machine to a guest VM. This is useful for things like bringing up multiple VMs to test database clustering without requiring you to manually copy large amounts of data into multiple locations on your host or syncing data from host to VMs. This project is still in the very early stages, so proceed with caution.
