Videos: Intro to OpenVZ 2013

| |

I was lucky enough to be a guest on the Sunday Morning Linux Review episode 115 to talk about OpenVZ. In prep for the show I wanted to provide the hosts with some recent, updated videos that show off OpenVZ. I made the following videos which are in webm format... so you can play them in your browser or download and play with a media player:

Screencast: Virtualization Basic Introduction

| |

I was asked to put together a presentation on Virtualization... and wasn't quite sure what the audience would want... so I put together a basic introduction that I can easily improvise on as the audience asks questions.

I designed the slides using Prezi which is a freemium web-based presentation site. It has lots of motion so watch out... but I did keep it rather simple - no pictures nor embedded videos. :)

Screencast: Pear OS Linux 3.0 "Panther" for Mac OS X fans

| |

I threw together a quick screencast that shows the recently released Pear OS Linux 3.0 "Panther" in action. Pear OS Linux is stylistically patterned after (some would say ripped off from) Mac OS X. It is my understanding that this is based on a customized GNOME 3.2 that shows yet again, just how malleable GNOME 3 can be with some effort.

Please excuse the SPICE connection glitches witnessed in the video. I generally don't run into issues with SPICE but this setup was a bit different with the visual affects that are turned on by default in Pear OS.

Screencast: History and differences of Xen and KVM

| | | | | |

I threw together a quick screencast for Dann from the Linux Link Tech Show explaining the history of and differences between Xen and KVM. Feedback is encouraged because I'm sure I have some mistakes in there.

Screencast: MontanaLinux Fedora 16 remix in KVM

| | | | |

If you didn't notice, today is Fedora 16 release day. Yeah! I've been using Fedora 16 for a while now preping my MontanaLinux remix. I made a 41 minute screencast that does two things: 1) Showcases the desktop environments available in Fedora as melded together in the MontanaLinux LiveDVD remix, and 2) Shows using KVM and virt-manager some.

Please pardon my voice and occasionally sniffing... an allergy is bugging me.

Screencast: SELinux Demystified

| | |

I slapped together an SELinux presentation for the BozemanLUG and some people said they wished they could have attended it but missed it, so I decided to record a quick screencast.

Please note, that I do not claim to be an expert on SELinux but I do present the basics. If anyone with more SELinux knowledge notices any mistakes, please let me know.

You can find it here:
selinux-demystified-bozemanlug-jan2010.ogv
91.2MB, ~34 minutes

It is an Ogg Theora .ogv file that I recorded with gtk-recordmydesktop. Right-click and "Save as..." to download. Or if you have a newer version of Firefox with .ogv support, watch it in your browser. The better experience is probably to download it. If your preferred media player can't play .ogv files, I recommend you check out VLC Media Player.

Screencast: Intro to Sugar on a Stick

| | |

Since so many adults who are "computer literate" seem to have problems getting started with the Sugar environment, I decided to make a brief introduction screencast. I boot up the Sugar On a Stick "Strawberry" LiveCD in a KVM virtual machine and show the basics of using Sugar as well as a few activities.

Screencast: Virtual Machine Manager, Fedora 11 Preview

|

I've been doing quite a few Fedora 11 installs on various hardware in preparation for the review of I'm working on but I wanted to give a short glimpse of KVM in Fedora 11 with the Virtual Machine Manager (virt-manager). I also show MontanaLinux (a Fedora 11 remix), some of the new features in Fedora 11 and some additional software.

For those running a browser that can do HTML 5's video tag (like Firefox 3.5 beta), you can watch the Ogg Theora version which is about 1/3 the filesize of the Flash version but bigger and better quality. Or download it: kvm-fedora11-preview-smaller.ogv (right-click, Save link as...)

Screencast: How to Build a Fedora 10 Remix

| |

I made a two-part screencast on how to build a Fedora Linux remix. The first video has some slides at the beginning that explains the process and then walks through it with a live demo. The second video boots the LiveDVD that was created, shows an "Install to Hard Drive" and then shows some of the features of the remix.

Why would you want to make a remix? Two common reasons:

1) You want updated install media that has all of the updates already applied. Given the fact that Fedora has a lot of package churn and a constant stream of security fixes, bug fixes and feature enhancement updates, their install media gets out of date pretty quickly. That is especially the case if you want to use an .iso image of the LiveCD media to make a LiveUSB out of.

2) You want more software included on the Live media than Fedora provides. The Fedora folks usually fill up a single CD but how about a LiveDVD with additional desktop environments, a slew of window managers, a ton of application software, and multimedia apps that Fedora won't include in the distro? That's what I make during the screencast... a custom LiveDVD with all of the updates applied and all of the additional software I want in a LiveDVD with a painless, quick install-to-hard-drive if desired.

Here is the end result. I boot the the LiveDVD image and even do an install.

Screencast: A Brief Introduction to OpenVZ

The first "Introduction to OpenVZ" screencast that I did was over 1.5 years ago and it has become somewhat outdated... so I decided to make a new one.
