[libvirt] libvirt issues in Fedora 21

[snaper at openmailbox.org]

Sorry if its not the right place to post.

Fedora 21 user here and I've run into two problems that were not there 
in Fedora 20.

First enabling hugepages causes a machine to refuse to boot. It gives 
errors saying "Error starting domain: Unable to read from monitor: 
Connection reset by peer "
This problem is easily reproducible, all you have to do is add the 
setting to any vm you have.

Second is the vm does not work if a shared folder is added. I only tried 
adding them as mapped mode.

Please try to fix them.
