== What is virtualization ==
[https://en.wikipedia.org/wiki/Virtualization Virtualization] is software/emulated or shared version of running hardware.
One can emulate various hardware combination, boot it from within your running OS,
and install supported guest OS and software on it.

Above is a short description, this is a vast area to explore, see some resource links below.

This page and some more in [[#Using_virtualization_(simple) | '''section simple''']] should get you started.

== Types of virtualization ==
* Aside from providing general virtualization tools/utilities packages, Alpine Linux supports virtualization extensively. See its download area exclusively for different platform it supports, [https://cdn.alpinelinux.org/v3.22/releases/cloud/ i.e. Cloud Images]
* Scope of this page is to get you started with basic virtualization, using general available hardware(see, [[#Test_bed | ''Test Bed'']]), for more see some [[#Resources | resource]] links below.

== Does my system/device support virtualization? ==
* Meaning, if your system/device provides some features to accelerate/enhance virtualization at hardware level.
{{Pill||TODO|goldenrod|yellow}}
* Add here bios screen-shots of some different brands.

{{Tip|Making changes to your bios should be considered '''advanced''',
approach it with '''CAUTION''' or ask your hardware vendor to enable it first for you.}}

<pre>
# cat /proc/cpuinfo | grep -io vmx | head -n1

vmx
</pre>

== Setup walkthrough ==
Basic check/setup to prep your system for virtualization usage.

=== Objective ===
# Install Alpine Linux.
# Verify if virtualization is enabled in bios.
# Enable/verify availability of <code>/dev/kvm</code>.
# Enable/verify correctly loading of ''kernel virtualization modules'' for usage.

=== Test bed ===
{{Pill||WIP|goldenrod|yellow}}
* Describe here the test bed/setup used to run the scripts/commands below.
# MODEL: Dell Laptop.
# CPU: Intel i5 3rd/4th generation with virtualization enabled.
# RAM: 8GB

==== Install Alpine Linux ====
# Diskless installs (Ram based)
# SYS installs

{{tip| - For further setup to work correctly, its assumed that Alpine Linux installed in, done for version between ''v3.21.x and v3.22.x''}}

{{Pill||v3.21.x-v3.22.x|cadetblue|lightblue}}
==== Manually fixing/enabling system level kvm modules (as root) ====
<pre>
# ls -l /dev/kvm

crw-rw---- 1 root kvm 10, 232 Sep 21 03:47 /dev/kvm
</pre>

This means your devices' virtualization feature is enabled in bios.

* Does this mean if <code>/dev/kvm</code> is not available running ''virtual machines'' is not possible?
** No, most likely you can still run ''virtual machines'', but may have some reduced performance or features.

Now, lets find your CPU brand/type.
<pre>
# cat /proc/cpuinfo | grep -E 'model name|Processor'

model name : Intel(R) Core(TM) i5-3340M CPU @ 2.70GHz
...
</pre>

Cpu is INTEL.

Lets load kvm module.
{{Cmd2|# modprobe kvm }}

Lets check current kvm modules already loaded.
<pre>
# lsmod | grep kvm

kvm 1392640 0
irqbypass 12288 1 kvm
</pre>

If this does not show/load CPU specific kernel modules yet.

Lets load it.
{{Cmd2|# modprobe kvm_intel # for INTEL cpu }}
{{Cmd2|# modprobe kvm_amd # for AMD cpu }}

<pre>
# lsmod | grep kvm

kvm_intel 409600 3
kvm 1392640 2 kvm_intel
irqbypass 12288 1 kvm
</pre>

CPU specific kernel modules are now loaded.

Simple Walkthrough

Vkrishn: add link About-virtualization-simple

== About Walkthrough ==

* These series of pages are for those who come to Alpine Linux, install it and say, hey I cannot get this or that started, or the previous documentations do not work.
* These set of pages ensures (at-least tries) that one can get started with an application for a given version of Alpine Linux installed.
* Feature of document is limited by its objectives.

== How to make best of it ==
* Follow the pill trails, Neo. :-)
* Try sticking to same versioned pills.

== Simple Walkthroughs ==
* [[About-virtualization-simple]]
* [[LXC_Alpinelinux_Simple]]
* [[Qemu-simple]]

== Guide note for adding new pages ==
* Scope of documents are limited by its objectives, therefore adding new features later to it should be avoided.
* Try keeping objectives as short steps.
* Try making the document complete in itself.
* Each paragraph should be marked by '''version pills'''. See [[Template:Pill]] for examples.
* Multiple version pills can be added/updated to same paragraph with new release of Alpine Linux.

== Fun with Algitbot ==
* Algitbot come, will take you to walk-through s-park. There I would teach you how to change your fuse, but, promise you would not faint once I pull it out.

Aports what is edge

Vkrishn: What is edge

== What is edge (The Definition) ==
: '''Short definition'''
:: Edge is a rolling release branch.

[Illustration] 
* bleeding edge
* tree on the cliff

== How packages move in edge (The Juggler) ==

What are repositories (main|community|testing) ?
See, https://wiki.alpinelinux.org/wiki/Aports_tree

# MAIN
## Main has a support cycle of 2 years
## Support the main repository for 1.5 year (a total of 2 years)
## We also try to limit the amount of packages in main to only include base system packages, in base you can think of packages which are needed by other packages or are needed to setup a basic system.
## Packages in main must not have dependencies in other repositories.
# COMMUNITY
## Community has a minimum support cycle of 6 months.
## Support will stop (you will need to upgrade to the new release to continue to have support)
## Packages limited if its a bloat
# TESTING
## No support (staging only), only built for edge.
## If it stays here long enough it gets moved to unmaintained/purged (gets cleaned up every 6 months)
## No limit
# UNMAINTAINED
## Unmaintained packages are not build.
#NON-FREE
## Don't ask, don't tell, we only like opensource.

[Illustration] 
* bananas for repos (green=testing, green/yellow=community, yellow=main)
* unmaintained(brown), algibot with closed nose, brooming it away
* non-free(transparent), we act as if they do not exist

== Packages that go to next stable release (The Reap) ==
Every new stable release will be a branch created from our master branch (our current edge release).
The only two repositories included in stable branches are main and community.
This means any package that is currently in our testing repository will not be included in our new release. This is because testing is a kind of staging directory where we test packaging before we move them to one of the two other repositories (most probably community).

Please also keep in mind that our community repository is still young so many packages will still need to be moved to community, we try to do that when we bump into them.

[Illustration] 
* Hoga-boga dance around fire
* Harvesting season

== What is stable release (Fruits of Labor) ==
- How to find latest stable release?

[Illustration] 
* Vacation to alpine wilderness

== Do we backport new packages(from edge) to previous stable releases (The Gift, Favor) ==
# Make a request on forum/irc, mailing list or add to bugs.a.o and wait.
# Don't forget to say why (in short).
# Be prepared for rejection.

[Illustration] 
* Algibot controlled drone dropping packages (the gift).

== How packages are deleted (The Purge) ==
Presently applies mostly to "testing".

=== Checks before purge ===
# If packages is feature complete
# If its stable and no equivalent package is available
# If its a hard-depends for another package.
# If its requiring extra maintenance then move to a lower priority level
# If its a problem, add to bugs.alpinelinux.org first, once bugs get comments, vote or veto
# If its in 'testing' long enough (this is shaky)

=== After purge ===
# Remember to replace with equivalent packages if its only of a kind
# Notify in "detailed changes list" in release notes (applies to main|community)

[Illustration] 
* Algibot shooting packages with nose clips on
* Algibot brooming it away

== Glossary ==
# '''Support''' - mostly security fixes and major software issues
# '''Special packages''' - packages voted to be special (not otherwise as understood as basic system package)

Vkrishn:

[http://lxc.sourceforge.net/ Linux Containers (LXC)] provides containers similar BSD Jails, Linux VServer and Solaris Zones. It gives the impression of virtualization, but shares the kernel and resources with the "host".

'''NOTE:''' Simple (howto) is meant for using LXC for quick installation of applications using HOSTs networking/ip (container config has, <code>lxc.network.type = none</code> ) and usage of application for development work. Most application have internal settings for PORTs which will be used where multiple versions of that application is needed to install. For production or live environment using [[bridge]] (br0) with [[LXC | full networking]] for container would be ideal, alternate use docker (both requires some experience with container technologies).

'''Target audience:''' Developers, Newbies

'''Tested on:''' AlpineLinux v3.3x(host+guest)

== Installation (base) ==
Install the required packages:
{{Cmd|apk add lxc lxc-templates bridge}}

Create a simple configuration template for the guests, ''/etc/lxc/simple.conf'':
<pre>
lxc.network.type = none
</pre>

== Create a guest ==

=== Using Alpine Template ===

{{Cmd|lxc-create -n dev1 -f /etc/lxc/simple.conf -t alpine}}

This will create a ''/var/lib/lxc/dev1'' directory with a ''config'' file and a ''rootfs'' directory.

If running on x86_64 architecture, it is possible to create a 32bit guest:

{{Cmd|lxc-create -n dev1 -f /etc/lxc/simple.conf -t alpine -- --arch x86}}

== Starting/Stopping the guest ==
Create a symlink to the ''/etc/init.d/lxc'' script for your guest.
{{Cmd|ln -s lxc /etc/init.d/lxc.dev1}}

You can start your guest with:
{{Cmd|/etc/init.d/lxc.dev1 start}}

Stop it with:
{{Cmd|/etc/init.d/lxc.dev1 stop}}

Make it autostart on boot up with:
{{Cmd| rc-update add lxc.dev1}}

You can also add to the container config: <code>lxc.start.auto = 1</code>

& {{Cmd|rc-update add lxc}}

to autostart containers by the lxc service only.

== Connecting to the guest ==
By default sshd is not installed, so you will have to connect to a virtual console. This is done with:
{{Cmd|lxc-console -n dev1}}

To disconnect from it, press {{key|Ctrl}}+{{key|a}} {{key|q}}

== Deleting a guest ==
Make sure the guest is stopped before removal:
{{Cmd|lxc-stop -n dev1}}
{{Cmd|lxc-destroy -n dev1}}
This will erase everything, without asking any questions. It is equivalent to: {{Cmd|rm -r /var/lib/lxc/dev1}}

== Installing applications in simple LXC containers ==
