New on the blogosphere today is a super-useful little Vagrant plugin from Juarez Bochi that takes screenshots for all active VMs.
After finding a command on VBoxManage for taking VM screenshots, he decided to wrap it in a script after which Igor Sobreira, who blogged about the idea, found out about vagrant plugins.
The result was the vagrant-screenshot plugin. and here's Igor's usage example:
$ vagrant screenshot -o [vagrant] Taking screenshot for default [vagrant] Screenshot saved on screenshot-default.png
Hopefully this plugin helps a lot of Vagrant users, or brings more awareness about Vagrant's power in general.
