[ovirt-users] oVirt: access ovirt-image-repository through Proxy

Hi expert, 'ovirt-image-repository' storage domain created by default in my ovirt 4.2 environment , but unfortunate my ovirt-engine and ovirt-node machines sits in a private network where it can only access external services through a HTTP proxy. Is there a way to tell ovirt-engine the HTTP-Proxy to use ? Thanks, Xu
