As I explained in an earlier post, Vagrant now supports Parallels as a provider. Since I wanted to test how they were working together, I created a standard 64bit Gentoo Linux box that you can download and use. In addition to a standard Gentoo install, the box also comes with Puppet installed, so you can do some actual work on it.
Since I presume you already have the Parallels provider setup by now, this is how you can download and use the box:
[code]vagrant init orpiske/gentoo-linux-64 && vagrant up[/code]
After the box is downloaded from the cloud you can use vagrant as usual (ie.: vagrant ssh, etc).
