[UPDATE 20131225 ]

Unmuting the channels

The current version of ALSA installs with all channels muted by default. You will need to unmute the channels manually.

It is easiest to use alsamixer ncurses UI to accomplish this:

$ alsamixer

Alternatively, use amixer from the command-line:

$ amixer sset Master unmute

In alsamixer, the MM label below a channel indicates that the channel is muted, and 00 indicates that it is open.

Scroll to the Master and PCM channels with the ← and → keys and unmute them by pressing the m key. Use the ↑ key to increase the volume and obtain a value of 0 dB gain. The gain can be found in the upper left next to the Item: field. Higher values of gain will produce distorted sound.

$ amixer sset 'Speaker' unmute
$ amixer sset 'Headphone' unmute

Debian GNU/Linux device driver check page

Boot your machine with a GNU/Linux OS (such as Debian, Knoppix, Redhat, and so on), run 'lspci -n' and paste the output into the box below, then press 'Check' button.

Notice:

• This database uses the PCI map of Debian kernel 3.2.0-4-amd64 .
• The result does NOT guarantee your hardware works perfectly.
• This database only verifies the PCI devices at this time. X drivers, ISA, USB, IEEE1394 or any other devices are out of the focus.

eg. lxc-create -n foo -f lxc.conf -t debian
The configuration file is often:

lxc.network.type=macvlan
lxc.network.link=eth0
lxc.network.flags=up

or alternatively:

lxc.network.type=veth
lxc.network.link=br0
lxc.network.flags=up

For more information look at lxc.conf (5)

At this point, I assume you know what you do.

1. Control Groups
=================

1.1 What are cgroups ?
----------------------

Control Groups provide a mechanism for aggregating/partitioning sets of tasks, and all their future children, into hierarchical groups with specialized behaviour.

                      CFS Scheduler
                      =============

1.  OVERVIEW

CFS stands for "Completely Fair Scheduler," and is the new "desktop" process scheduler implemented by Ingo Molnar and merged in Linux 2.6.23.  It is the replacement for the previous vanilla scheduler's SCHED_OTHER interactivity code.

Linux Containers

Linux Containers (LXC) are an operating system-level virtualization method for running multiple isolated server installs (containers) on a single control host. LXC does not provide a virtual machine, but rather provides a virtual environment that has its own process and network space. It is similar to a chroot, but offers much more isolation.
