Virtualization has been a buzz word for a few years now. Some people think it has been over-hyped but I'm not one of those people. The big competing products seem to be: VMware, Xen, KVM, VirtualBox, Parallels (including OpenVZ), and Hyper-V.
Is there too much choice out there? Choice isn't bad, is it? Will there eventually be a market shake up with a thinning of product candidates as a result? Will someone try to proclaim that they are the virtualization "standard"? I don't really know. I certainly like competition and don't think having a number of competing products is bad. There are both proprietary products and FOSS products. As you can guess, I lean towards the later if at all possible.
Update: Full article now includes two embedded flash videos from Red Hat.
Proxmox VE version 1.1 does not ship with a firewall. This is a bad thing for a production server for obvious reasons. Proxmox VE 2.0 is supposed to ship with firewall support built in. Until that time here is an easy script that you can put on your Proxmox VE box to protect it and the virtual machines running on it, if you so choose. This is based off of http://wiki.openvz.org/Setting_up_an_iptables_firewall but works with KVM machines and tailored to a Proxmox install.
Installation and Usage
Proxmox VE is a “bare metal” ISO Linux distribution that is a virtual machine platform. It is geared towards enterprise users and designed to be installed on enterprise grade hardware. The Proxmox VE distribution combines two virtual machine technologies; KVM and OpenVZ as well as a web interface to manage everything. Proxmox VE also integrates into its web interface a way to manage multiple computers as a cluster. For the rest of the article Proxmox VE shall be referred to as PVE. This article is written about PVE 1.1, the latest stable release.
Brian said he has been working in a Windows only shop and for the presentation he had installed Linux (Fedora 10) on his laptop for the first time in a long while. Glad to see it actually worked well.
It is nice when a presenter uses Linux to give their presentation at a Linux meeting, huh? He actually ran his slides from Powerpoint 2003 under Wine as one of several examples he gave of how well some apps work.
Attached you will find a PDF version of his presentation. Enjoy!
Keir Thomas has released a new book (January 2009) , Ubuntu Pocket Guide and Reference and interestingly a pdf version is freely available for download.
I have taken a brief look at the PDF and it contains some interesting information and there are chapters on the command line interface (bash) and security, including encryption.
Ubuntu 8.10 Intrepid Ibex didn't come with the newest version of Open Office, due to Open Office 3 not being released early enough for the developers to test it. If you don’t want to wait for the developers of Ubuntu to release Open Office 3, you can open synaptic package manager and add:
deb http://ppa.launchpad.net/openoffice-pkgs/ubuntu intrepid main
to your third party software sources. Then update. Worked like a charm for me.
Just thought I would let everyone know that we have a public Ubuntu mirror on the Montana State University campus Bozeman. Feel free to use it as much as you would like. The mirror server is connected directly to our backbone network with gigabit speeds. Anyone on campus and at our regional campuses (Billings, Great Falls, etc) should benefit from very fast updates as well. Anyways here is the information:
I was wondering just how many OpenVZ containers I could create on a beefy machine and how many processes the Linux kernel would be happy running so I decided to do an experiment.
I have two OpenVZ hosts... one is the primary and the other is a backup machine. Both of them are HP Proliant DL380 Gen5 machines with dual, quad-core Xeon processors, 32GB of RAM, 32GB of swap, and a 600GB /vz partition. I decided to use the backup OpenVZ machine for the experiment.
Wow, being a guest on The Linux Link Tech Show... with fantastic hosts Dann, Linc, Allan, and Pat... was great. I had a lot of fun. Yes, there were some technical problems at the beginning of the show that caused it to start a little late... and unfortunately I didn't have a way to boost my volume... and I don't know how it sounded live because I wasn't tuned into the live stream... but the archive recording isn't too bad. I'm guessing Dann cranked up the volume whenever I was talking.
For those who missed the live show, here are links to the .ogg and .mp3 archives:
Is this guy just an idiot? Or something more sinister, like a puppet?
Does he actually believe his own crap?
"Linux is great. It's a free, open-source operating system (OS) based on work done by Linus Torvalds in the early '90s. Again, it's free, powerful and easy to ...
