Call to virDomainS (Libvirt::Error)failed: operation failed: Error -22 while writing VM

[flavio-fernandes]

Heh... this is probably less relevant on vagrant 1.8, which provides a native snapshot command set. Regardless of that, I want to take this moment to publicly say thank-you sahara plugin, for the many hours it had saved me since I first used it. You rock!

using libvirt provider on centos 7 system, with vagrant version 1.7.4 I hit this issue when trying to enable sahara sandbox. This is after trying the fixes for the fog issue, mentioned in pull #50
