Dispelling Common Cloud Myths
Is there someone in your office that complains constantly yet offers no useful suggestions on how to fix the problem at hand? Do you wonder if some people just thrive on complaining and tickling the skeptic bone in others? Are you sick of the abundance of conflicting and often confusing information? When it comes to [...]
The Xen Dom-u Kernel And The Kitchen Sink
Does anyone still like configuring and building their own Linux kernels to taste? I do. Call me a nerd, but I actually enjoy spending countless hours slimming down my kernel so it has just enough support for my hardware, with modular support for anything that I might be inclined to plug in. No, the performance [...]
You May Have Xen – But How About Tofu?
Enough procrastinating. I have been working on a Xen friendly operating system for several years, a lot of the time has been spent waiting to see what happened with pv_ops in mainline Linux. Two years later, we’re still waiting to see what happens to pv_ops in Mainline Linux. Everything else (such as the Xen API, [...]

A slightly better Xen console

What I do not like is what the redirect does to the terminal when using stuff that heavily depends on ncurses, like ‘top’ or the midnight commander. If your not familiar with minicom, its a simple ‘telex [...]

Xguests does not require xend to be running and will print information in the following formats: XML 1.0 PHP Array Perl Array BASH Array Easy to scrape text CSV ‘xm list’ style
Ubuntu Hardy/Xen templates nearly done
I’m now putting the finishing touches on some Ubuntu Hardy templates for Xen. I’ll be contributing both 32/64 bit templates to jailtime early next week. I’ve decided that continuing to make these manually each time Ubuntu releases is a pain, so I’m nearly done scripting the whole thing. I’ll release a package with the build [...]
