Bug 1175175

Workaround: remove it manually if not needed.

Note to QE. To verify, the following, on a clean new machine, should work:

# yum install rhevm-setup-plugins rhevm-setup-base
# engine-setup

A reproduction (meaning, without the patches for this bug) will not install the engine, and engine-setup will fail.

A verification will currently (3.5) pull the entire engine and succeed.

In a future version we might ease some dependencies, so that it will only pull in engine-setup, and not the engine, so that if user replies 'No' to 'Configure Engine?', engine packages are never downloaded or installed. In such a future version we should also make sure rhevm-setup-plugins won't fail in other ways later.

I installed ovirt-engine-setup and ovirt-engine-dwh-setup
Removed ovirt-engine and ovirt-engine-setup
Setup still fails due to PluginLoadException: No module named engine

ovirt-engine-setup-base-3.6.0-0.0.master.20150628172322.git3c12761.el6.noarch

Tou can't test this with ovirt.

Moving back to modified, waiting for a rhevm build

This error message is different from the one in the description, so it's a different bug. Please open one. As the message says, it's a bug in vmconsole_proxy_helper's setup plugin, which needs the engine's but does not require it. Pushed a fix [1]. Thanks for the report!
