Re: [Engine-devel] 3.3 scratch or upgraded installation must use Apache proxy (https://bugzilla.redhat.com/905754)

Hello, I don't understand why you start discussion from start... there were some additional facts. So first answer: No we cannot assume we own the machine nor own the apache, nor own the postgresql. These assumptions made in the past were plain wrong and cause more harm than good, and eventually saved no resources nor efforts. At master we altered the ajp proxy configuration to be less intrusive[1][2]. We split the http configuration into three: 1. Install ajp proxy per our URIs[1]. 2. Optionally set root redirection from / to /ovirt-engine 3. Optionally configure mod_ssl with our certificate.

The mandatory apache configuration[1] does not alter any configuration file, hence the chance of conflict is the chance of conflict between ovirt-engine URIs and other product URIs. ovirt-engine URIs: --- /UserPortal /OvirtEngineWeb /webadmin /docs /spice /ca.crt /engine.ssh.key.txt /rhevm.ssh.key.txt /ovirt-engine-style.css /console.vv /api /ovirt-engine --- As we have done this without cooperation of developers we kept URIs as-is. URIs that cannot be changed until next major: /engine.ssh.key.txt /rhevm.ssh.key.txt /ca.crt /api [I guess, although we can provide migration path alternative] All the other can be moved into /ovirt-engine with cooperation of developers, especially UI and Virt developers, it should be easy to do this, and reduce the chance of conflict.
