In the change log, I’m happy to see “improved the resilience of some Virtualbox commands.” At Airbnb, we used to use Vagrant with Virtualbox and the Chef provisioner to create our dev environments, but we migrated totally away from Vagrant after struggling with Virtualbox bugs, and strangeness with Vagrant’s internal state and locking. Seems like this issue is finally addressed: https://github.com/mitchellh/vagrant/i…
It's been such a source of frustration that there is no better shared folder alternative. VirtualBox is the only usable cross-platform backend, and vbox shared folders are the only way to have two-way syncing between guest and host. I don't understand why it's so poorly supported :/
