Xguests (final?) released
I’ve finally gotten around to properizing the Xen version of my XMLPulse tool. Its been re-named to Xguests and is available for testing. There’s a bunch of changes, I took out almost as much as I added. The biggest change is Dom-0 /proc information is no longer part of the tool, its only for quick [...]
Xen and the art of web hosting
I’m working on a pretty comprehensive book aimed at helping web hosting providers adopt Xen for some of their offerings. Xen ‘out of the box’ is a really nice platform designed to make as many people happy as possible. Web hosts have special needs that require special planning, a guide to planning and implementing Xen [...]
A few new tools for Xen
I’ve updated my xmlpulse tools to include some new features, including a program that queries xenstat to produce PHP arrays of guests. Also included is a program to dump guest information into simple bash arrays, handy for scripts. Dom ID, CPU usage, ram usage , etc are included. Libxenstat is sort of like libvirt, much [...]
Yet another virtual appliance
In my on-going effort to make the building blocks for a “poor man’s” cluster, I’ve decided to get to work on some virtual appliance images suitable for use with Xen (and possibly others). Pound is a great load balancing tool. Its light weight, super easy to configure and pretty reliable. Depending on the kind of [...]
Virtualization does NOT decrease security!
Theo de Raadt made some rather general (and sweeping) statements regarding how virtualization might or might not increase or decrease security. I’m not at all concerned with the things that he suggests. Many programmers have never had to deal with the hosting (IAAS) industry. When you sell access to GNU/Linux (Or BSD) computers to anyone [...]
How busy is your Xen host?
Several people have written to me asking how to determine how ‘busy’ their Xen hosting provider’s servers have become. I just love new buzzwords, ‘busy’ now indicates how many VPS accounts that a web host packs on a single machine. To scope out a Xen host, you need to ask them some questions about their [...]
Ubuntu Feisty Xen image available
I’ve been promising several people for the past couple of months that I would make a Feisty Xen guest template when I got “around to it”. Well, I got around to it and the template is available for download. You’ll find the md5′s in the directory listing. The template was bootstrapped (32 bit) using debootstrap, [...]
GNUPanel soon open to developers
I’ve received notice from Jorge and Ricardo, the lead developers of GNUPanel that very soon I’ll have a new semi-properized set of installation scripts. Once I get them, Mercurial repositories will be created. I’m planning the following: public/ Branches from core developers Main (stable) public branch Dev (unstable) public branch queue/ Patch queue for stable [...]
