Title: Adjust config file path for Proxmox version 2 clusters

Proxmox 1 used /etc/qemu-server for storing configuration files. Starting with Proxmox 2 the files are managed
through the Proxmox Cluster file system (pmxcfs) inside /etc/pve/nodes/$HOSTNAME/qemu-server, see
http://pve.proxmox.com/wiki/Proxmox_Cluster_file_system_%28pmxcfs%29 for details.

I'm using this on a Proxmox cluster version 2.1-13. If support for Proxmox 1 versions is still worthwhile in your opinion it might be worth checking for the according Proxmox version and then adjust the directories accordingly on the fly, the patch should give you an idea what to do. :)

Thanks for proxmox-utils! :)
