Some documentation fixes + link to my Docker/LXC guide
I added a link to my guide about using docker containers + LXC (I am planning to maintain this at work for future bitcoin versions), then I mentioned other virtualization options (KVM, LXC). This commit includes a fix issue for documentation issue #4269 that consists in telling users to checkout correct bitcoin version before using the gitian descriptors (otherwise all hell can break loose). Also, I replaced URL for Debian 7.4 ISO with a correct one and added link to official Debian ISO sources.

Preparing the Gitian builder host
|
||||
---------------------------------
|
||||
|
||||
The first step is to prepare the host environment that will be used to perform the Gitian builds.
|
||||
In this guide it is explained how to set up the environment, and how to get the builds started.
|
||||
|
||||
Debian Linux was chosen as the host distribution because it has a lightweight install (in contrast to Ubuntu) and is readily available.
|
||||
Any kind of virtualization can be used, for example:
|
||||
- [VirtualBox](https://www.virtualbox.org/), covered by this guide
|
||||
- [KVM](http://www.linux-kvm.org/page/Main_Page)
|
||||
- [LXC](https://linuxcontainers.org/), see also [Gitian host docker container](https://github.com/gdm85/tenku/tree/master/docker/gitian-bitcoin-host/README.md).
|
||||
|
||||
You can also install on actual hardware instead of using virtualization.

||||
|
||||
Create a new VirtualBox VM
|
||||
---------------------------
|
||||
|
||||
The first step is to create a new Virtual Machine, which will be explained in
|
||||
this section. This VM will be used to do the Gitian builds. In this guide it
|
||||
will be explained how to set up the environment, and how to get the builds

started.
