## Introduction
|
||
|
|
|
||
|
|
This article tries to summarise Linux Virtual Machine
|
||
|
|
methods and is in its early stage.
|
||

## Raw import of notes
|
||
|
|
|
||
|
|
The following notes I made some months ago, which will
|
||
|
|
be the basis for this article.
|
||
|
|
|
||
|
|
|
||
|
|
Try all of them and handle them via creature!
|
||
|
|
|
||
|
|
status
|
||
|
|
------
|
||
|
|
eth: ip addresses / mac / dhcp
|
||
|
|
|
||
|
|
|
||
|
|
vmware
|
||
|
|
-------
|
||
|
|
different host os
|
||
|
|
|
||
|
|
|
||
|
|
lxc
|
||
|
|
---
|
||
|
|
Not completly isolated. Linux only. Many changes to the guest os.
|
||
|
|
Some scripts existent (lxc-debian, lxc-fedora). The latter does
|
||
|
|
not work on debian.
|
||
|
|
|
||
|
|
lxc-debian mit cache (schlau)
|
||
|
|
no real hypervisor existent.
|
||
|
|
|
||
|
|
mac / ipv4 management missing => creature
|
||
|
|
|
||
|
|
adjust init. change dev. do not run udev (why?)
|
||
|
|
|
||
|
|
Root open in the filesystem. Nice. Quota?
|
||
|
|
|
||
|
|
Ressources are shared, if nothing else is specified.
|
||
|
|
=> network = all!
|
||
|
|
|
||
|
|
First installation - than virtualisation!

how tos
|
||
|
|
different methods

||
|
|
which way for which vm-type
|
||
|
|
|
||
|
|
Network
|
||
|
|
-------
|
||
|
|
Always dhcp? Either on the vm-host or external.
|
||
|
|
Reason: Easy to configure. Scales dynamically.
|
||
|
|
|
||
|
|
How to handle bridges etc.? Independent of the os?
|
||
|
|
Reuse OS
