What are the reasons for those installation/setup issues and how to fix everything?

Dear HUBzero Team,

This is my first post on this site. Thus, first of all, let me thank you for all your hard work on such an interesting software platform and congratulate on your achievements. Using this opportunity, I also would like to wish you and your families a great holiday season and happy and healthy New Year!

Now I will describe my problem. I'm a research scientist at Georgia Tech, currently evaluating potential use of HUBzero as a foundation for our future e-collaboration platform for materials science. After reading a lot about HUBzero as well as alternative and complementary technologies, it has been decided to install HUBzero for feasibility testing/evaluation. Per your recommendations, I was performing the installation on Debian 7 (7.9, to be exact) with a default kernel 3.2.x. Since testing scientific workflows and tools will/might be a part of my evaluation, I proceeded with all steps up to and including the installation of OpenVZ kernel (2.6.x). Then things started going south: networking on my machine stopped working (I actually spent quite some time investigating and wrongly blaming my Ethernet port before realizing that it seems that the OpenVZ kernel or some steps during its install might have been the reason for the issue - I'm making this conclusion, since booting the original kernel restores the network connectivity). Perhaps, I'm wrong, but currently that's the only decent explanation I have. I even thought that my further steps somehow messed up networking on the machine, so after (the almost complete) install, I re-installed and re-enabled OpenVZ to identify the source of the problem. Unfortunately, upon OpenVZ install and switch to its kernel, networking stopped working, confirming my suspicions. So, the question is: what is going on with this and what to do about it?

In addition to that, before switching back to OpenVZ kernel, I have decided to return to the original Debian 7.9 kernel (3.2.x) in order to restore network connectivity and "finish" the installation. I put "finish" in quotes here, since I figured it doesn't make sense to install certain parts of the system, which seem to be dependent on OpenVZ kernel. So, I have installed all other parts, hoping to see, at least, the basic functionality. However, unfortunately, I am unable to see any Web page on the system - it seems like the Apache configuration is incorrect (as Apache processes are running). I suspect that the FQDN settings might be wrong (in "/etc/hosts", I commented out "localhost" entry, per your guidelines, and changed the FQDN value for "127.0.1.1" to match my desired name in <desired>.<domain path>; I also created "<desired>.conf" file in "/etc/apache2/conf.d" directory, with ServerName directive: "ServerName <desired>"). In this context, the question remains as well, as follows: what is going on with this and what to do about it?

Thank you very much for your attention. Any help and/or advice will be greatly appreciated.

Sincerely,
Aleksandr Blekh

    UPDATE: Finally, after some tinkering with configuration and successfully accessing the default site via FQDN from the same computer, I think that was able to narrow down the issue and confirm my preliminary conclusion that the Web access issue is not due to wrong installation or misconfiguration of HUBzero per se, but rather some kind of mistake or misconfiguration of the external access to the server (routing, port authentication or something else?). I hope that this will help people to guide me in the right direction, at least, in this regard (the OpenVZ kernel issue remains, too).
