Screencast: Introduction to OpenVZ
I learned about a handy dandy program today named recordmydesktop and the GUI for it, gtk-recordmydesktop. Seems to work pretty well. How well? So well that I actually ran out and bought a microphone so I could record the following video.
I've done a few presentations on OpenVZ and I had some slides made so... what the heck... I thought I'd slap together a presentation video.
The video is 800x600 and I didn't want to stretch the center column on the front page, so read the full story to see the included video.
[Updated: The volume on the original video was very soft so I upped the gain quite a bit.]
For a much better quality version of this video, feel free to right-click on the avi link and save as: openvz-introduction.avi
I had a little trouble with command syntax in a few areas, but please remember I didn't edit this video... and it is basically live. One unexpected failure was the "live migration". At the present time, I'm not sure why it didn't work... but offline migration worked just fine... and it had an guestimated downtime of maybe... 10 seconds... so that isn't bad. Offline is "offline" because it has to stop the VPS on one physical host and start it up on the other... and that takes a few seconds. The syncing of the filesystem goes while the VPS is running and it is only down while stopping the original and starting the new... which only takes a few seconds. It is basically like a really, really fast reset BUT the VPS is running on a different physical host. Any questions? :)
