@rafael: Yes, I think it makes sense to support sub-paths. It will make things a lot easier to work with. The security question is an interesting one. I am not sure I would be the best person to answer that. I would say that we would want to have the MD5s hosted in the same repo as the mirror list urls.
I do like the idea of running a web server on the management server for hosting the system vms though. It could be used to populate secondary storage and could potentially give operators an easier (more efficient?) workflow for introducing new templates. That area could use some work... *Will STEVENS* Lead Developer <https://goo.gl/NYZ8KK> On Mon, Feb 27, 2017 at 4:36 PM, Chiradeep Vittal <chirade...@gmail.com> wrote: > Hashes are checked (md5 IIRC) today. > But given the issues, I think the project should steer away from hosting > templates except the systemvm template. > > On Mon, Feb 27, 2017 at 1:31 PM, Rafael Weingärtner < > rafaelweingart...@gmail.com> wrote: > > > Will, I think we could support different path structures.
