title: How to resize a linux container in proxmox
body: <p>I'm trying to change an lxc container size in new proxmox 4 on debian jessie.
  But there is no checkbox (which was in openvz containers) for changing a size from proxmox interface.
  Changing a size in lxc container configuration file and restarting the services won't help.
  Backing up a container and then restoring it doesn't give an option of changing a size as well.</p>
