Reporting a bug.
I installed the virtualbox plugin. went into it and selected a VM directory. Clicked enable and it throws an error
Failed to execute command 'export LANG=C; omv-mkconf virtualbox 2>&1': sh: 1: Syntax error: Unterminated quoted string
The reason is my folder name was /Media/VM's/ and the quote in the folder name errors out. I'm not sure if the error is from the plugin or from the chunk handling shared folders but the input needs checked for quotes as they're valid characters in folder names.
I changed the folder name to VMs and it looks to work fine now.
