oVirt has several features that make it perform HTTP requests to an external resource. Notable examples are the Glance image provider and the new 4.x ability to pull images by specifying an external URL to get them from. These external resource may reside outside of the local network, that may make organisations desire to route such request through a web proxy. Case to point - most HTTP requests going out of oVirt's own PHX data center go thorough a Squid caching proxy server in order to accelerate CI performance and conserve outgoing bandwidth. It should be possible to set proxy settings either for a specific resource (traffic to that Glance provide should go via that proxy) to the whole system or to a specific DC or cluster (Hosts in the TLV DC should go via the TLV proxy) Alternatively we could try to adopt some standards to let admins use external configuration management tools to handle this, for example, support DHCP proxy attributes or WPAD or the '*_proxy' environment variable supported by wget and curl.
