How I can install ovirt on one server? - virtualization

I have one server.
And when I install ovirt I can open web interface at
But, then I try instal host on after that I can`t open
So, how I can instal ovirt-engine and host on one server?
Can you give me link to any tutorials?

You should follow the official quickstart guide
This definitely works for oVirt release 3.6 and Fedora 22 Server.
After you add the host in the webgui, it deploys necessary packages and configurations on the host. One of these steps configures and starts iptables. Maybe you first need to disable iptables and reconfigure it and that's the reason why your ovirt-engine isn't available after your deployment is finished. You can read the details which ports to open for iptables in the Quickstart Guide.
If you use CentOS this post maybe also helpful

If you're going to use a single host for both engine and run vms, the supported and suggested configuration is to use Hosted Engine.


Access web project on mac host from Windows parallels

I have found a lot of similar discussion, but non of it really helped.
When I tried to run PHP web project on Mac and access from virtualized Windows, I got correct result on multiple ports.
I think, that this means that I have correct settings in parallels and firewall (I didn't set any port forwarding on parallels and I have set 'shared networking'). Also SQL db from virtualized Windows is accessible on Mac without any issue (in this case, db port is forwarded).
My issue appear when I tried to run Coldfusion project on Commandbox.
My project runnig on localhost:61212 for example.
I tried port forwarding on parallels, from 61212 to 61212 on correct IP address.
Also tried to edit /etc/pf.conf. I add pass in proto tcp from any to any port 61212 and did sudo pfctl -f /etc/pf.conf.
But because of mentioned PHP experience, maybe I need to correct setup of Commandbox Coldfusion, but I don't have any clue where to do this.
Of course firewall is off on both.
Last think what I tried was install of Bonjour on Windows according to some discussion on other forum.
Thank you for any help.
If port 80 is available on your Mac, you can try to configure CommandBox to start ColdFusion on port 80.
At the box prompt (in your app root directory), with the server stopped, type:
server set web.http.port=80.
This will create a server.json file with the content:
You can find out more about how to configure CommandBox with the help of a server.json file, as described in the docs:
One solution could be run commandbox server on Paralles. When server can running upon shared project file and it could connect to mysql on host, source code could be edited as usual and site could be reload on paralles. Little slow, but all fine.
But it exists better solution.
For case that host ip is and wanted port is 12345.
box server start host= port=12345 see doc
Then access from paralles by url Same url is accessible from host.

How to generate the configuration to connect to a remote Kubernetes host

I have finished setting up a test Kubernets host running on a bare metal Centos 7. This will be used as a test system as we will be deploying everything in IBM Bluemix Kubernetes service.
Getting the configuration from Bluemix is easy... and while our Kubernetes on Centos works OK I don't know how to generate the configuration to access it from our workstations. It is explained at
but I am new to setting up a Kubernetes host... and have no idea where that
$ cluster/
command is... or which package to install to get it.
Thanks for any guide on this.
You can try option see, copy admin.conf file to your workstation, then run
kubectl --kubeconfig=./admin.conf proxy -p 80
after this your can access your dashboard from workstation http://localhost/ui

How do I install fusionpbx on my Amazon server(aws)?

I installed centos7 on aws. And I installed aws with the usual Fusionpbx installation method. However, after I installed Fusionpbx, ERR_CONNECTION_TIMED_OUT error occurred when I connected to https: // in window10.
Even if you disable HTTP and HTTPS inbound on the firewall, the error still exists.
How do I install fusionpbx on aws?
The install instructions for CentOS and other Operating Systems are located here. The preferred and most polished operating systems for FusionPBX are Debian (preferred by FreeSWITCH Developers), FreeBSD, CentOS in that order.

shinyproxy basic basics (+ some general web knowledge)

The problem
While searching for ways to deploy shiny apps I stumbled across ShinyProxy. From what I understand it's an alternative for ShinyServer. However, I lack some (very basic) knowledge to follow the guide provided.
The questions
Can ShinyProxy be installed just on any bought/rented server? Do I need to preinstall some other software?
Where do I type in the commands provided in the ShinyProxy guide?
Does Docker need to be installed on the server or is it a tool to deploy to the server and is thus installed locally?
The ShinyProxy guide misses a point about installing ShinyProxy. Why? Is it not installed (or is installation so obvious)?
I couldn't actually find instructions on how to run a shiny app with ShinyProxy.
The authors of ShinyProxy can probably provide a much better answer, but here is my understanding:
Your server needs to support Java 8 and Docker (or you can install Java 8 and Docker on your server).
Assuming you logon to your server via SSH, the commands will be typed in the SSH terminal.
Yes Docker needs to be installed on the server
It appears that ShinyProxy does not need to be installed. You just need to download it (the shinyproxy-0.5.0.jar file) to a location on the server, and then run java -jar shinyproxy-0.5.0.jar (in your SSH terminal)
To run a Shiny app, you need to package it as an R package first, then build a Docker image for the R package. The app is then actually running inside a Docker container. You also need a configuration file to tell ShinyProxy where to look for your Docker image. Example is here

Adding a Host on CloudStack development environment

I set a CloudStack development environment on Ubuntu 12.04 according to [this]
It works well, but I can't add a host through the management server UI.
I tested on released binary one, It could add the hosts. (Hypervisor: KVM)
I confirmed the log on terminal while the management server is running, It just said "unable to add host".
How can solve this problem?
Send this question to the Apache CloudStack developer mailing list.
Be prepared to provide a copy of the command you used to start the management server, the exact text from 10 lines before and 10 lines after the "unable to add host" message, and a copy of any exceptions that occured before this message.
I solved myself!
That's because of version. My CloudStack management server source version from GitHub was 4.2.0. But agent version was 4.1.0. So I changed source version 4.1.0. And, It was working well.
