Description of problem:
Currently, when importing XEN VM, URI path needs to be entered each time the user is required to import VM from XEN.
It would be nice to have an ability for adding XEN as an external provider, so each time import dialog is opened, the user will be able to select XEN source from import dialog > external provider dropbox, instead of entering it manually.
Version-Release number of selected component (if applicable):
this is nice to have but not that important - since in vmware user need to enter 7 fields in order to import but in Xen it only needs to enter one field - the url. (since its ssh key exchange based).
I think it's reasonable:
1. It's not a highly used feature.
2. The URI is pretty regular in libvirt world.
