[virt-tools-list] [PATCH virt-viewer] ovirt-foreign-menu: Set new ISO name using GTask API
Eduardo Lima (Etrunko)

Thu Nov 3 14:39:51 UTC 2016
From: Christophe Fergeau <cfergeau at redhat.com>
This is done with the new ovirt_foreign_menu_set_current_iso_name_async
function. Also, an error dialog will be shown in case anything goes
wrong with the async method.
