Move Centos system from Virtualbox to Raspberry Pi 3

Posted on 2016-08-04
Last Modified: 2016-08-06
Hello, so I have these Centos Virtual Machine which I'd like to "move" to a Raspberry Pi 3.
Now, the VM has x86 architecture while the RPi3 has Arm architecture, so I won't be able to just clone the system.

So I was thinking, which would be the smartest or at least quickest way to proceed? I'd like to avoid reinstalling all packets and reconfiguring them, most of all because I didn't originally configure the VM and it contains Asterisk, which I have no idea how to setup.

Hope someone can help me, thanks.

First concern, if you are running Asterisk, then Rasp Pi is going to be WAY way slow.
Just for proof of concept, I've setup a simple LAMP stack running a default Wordpress install. It worked. That's about all I can say for it. Literally a minute for one default index page to load.

Unless you are doing this as a toy to play with, you do not want to put anything in production on a Rasp. Pi.  
But, it will apparently run FREE PBX + Asterisk, this person has done it - albeit he's just lining some personal phones. Corporate use....wouldn't even consider it, personally.

It won't work. You would first have to rebuild the kernel etc for the Arm architecture. After that you would need to recompile every program you use to run under Arm from source. CentOS currently has no Arm support.

Ubuntu has some versions that support the Arm architecture, or you could build your own Arm version of Linux by using Gentoo for example.

Pidora, a Fedora "remix", is close to CentOS. Just FYI.

You could install the Centos Raspberry Pi3 using the below link

and then use rsync to move all the Asterisk install (directories etc) between the hosts (as well as other data that you want to move between them).

This is not for corporate use, it's for a simple voip switchboard in my home.
I had already downloaded the RPi3 version of Centos, I'll try Tomas' solution and get back.

Thanks, it worked just fine. I will revert to Raspbian though which is optimized for the Pi. My colleague is running a whole lot of Pi 3s as switchboards for small offices with no problem whatsoever. Looks like they're far more powerful than Pi 1s.
