====== Storage ======

===== Content =====

You have to set the content of a storage to actually use it. Keep in mind, each content type requires a specific sub directory. For example, if you add an NFS storage for ISO files and you don't have a sub folder which is called iso with all the ISO files in it, you won't see any ISO files to mount to your vms. 

^Name^Description^Directory^
|images|KVM-Qemu VM images||
|rootdir|Allow to store container data||
|vztmpl|Container templates||
|backup|Backup files (vzdump)|dump|
|iso|ISO images|iso|
|snippets|Snippet files, for example guest hook scripts||
