[Fedora-xen] virt-manager make check errors and connection errors

[Dan B. Phung]

awesome, it works!  kinda....as root it can list the vms, but as a 
regular user it repeats this message:

  libvir: error : operation failed: xenProxyListDomains

which files does virt-manager require suid perms? 

thanks,
dan
