Description Yedidyah Bar David 2013-10-28 17:22:01 EDT
Description of problem:

engine-backup --mode=restore does not let httpd access the network in selinux,
as does engine-setup. This means that on a system where engine-setup was never
ran, httpd fails to connect to the engine.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Install a new system, install rhevm
2. copy some backup file from another system
3. restore it with engine-backup --mode=restore
4. start the engine, restart apache
5. Connect with a web browser to the web admin

Actual results:

apache fails, with this in the error log:

[Mon Oct 28 23:10:06 2013] [error] (13)Permission denied: proxy: AJP: attempt to connect to ( failed
[Mon Oct 28 23:10:06 2013] [error] ap_proxy_connect_backend disabling worker for (
[Mon Oct 28 23:10:06 2013] [error] proxy: AJP: failed to make connection to backend:

Expected results:

apache should succeed

Additional info:

To fix, I ran:

semanage boolean --modify --on httpd_can_network_connect

We decided to "solve" this by requiring the user to run 'engine-setup' (which will do an upgrade) after restore.

See http://www.ovirt.org/Migrate_to_Hosted_Engine for an example on how to do that.
