I did a quick test running vagrant with the lxc provider inside Ubuntu 14.10 in a Parallels VM on my Mac -- it works! (Didn't yet try re-exporting the /vagrant dirs to the host Mac OS X system but it should be doable using standard sharing tools.) Downside currently is that it doesn't seem to support *transparently* using a VM as the container host the way the Vagrant Docker provider claims to -- it looks like you have to install and use the Vagrant CLI tools within the VM. But, it has the plus that you can use a stock VM if you're going to run Linux anyway. This is a plus for me as I use VMs for a lot of testing and prefer Parallels for its much better/faster graphics support. (I had been making do with VMWare Fusion and the for-pay VMWare provider plugin for Vagrant, but VMWare's drivers are a lot slower.) Note that LXC doesn't require enabling nested virtualization or anything super-scary like that, so it ought to work in any VM host. Notes: * install Ubuntu 14.04 Trusty in a Parallels VM ** disabled various Parallels sharing options to make sure it's not hogging my home dir ** kicked RAM from default 1gb to 2gb for headroom * install vagrant 1.7.2 (current) from vagrantup.com * $ vagrant plugin install vagrant-lxc * $ vagrant up --provider=lxc ** NFS failed? * did the apparmor config thing from the readme https://phabricator.wikimedia.org/diffusion/MWVA/browse/master/support/READ… * $ vagrant destroy * $ vagrant up --provider=lxc -- brion On Tue, Mar 3, 2015 at 1:00 PM, Bryan Davis <bd808(a)wikimedia.org> wrote:

However, it then makes it MediaWiki-specific in many ways (running services, contents of /vagrant, etc.) My understanding is that the LXC provider allows essentially any Ubuntu VM. Then, you can use that VM for general work, as well as run one or more LXC containers (including but not limited to the MWV one) in isolation. With the VirtualBox provider, you can't run multiple different Vagrants (e.g. WordPress, MediaWiki, etc.) on one VM. Matt Flaschen
