xen

Pete Zaitcev (zaitcev), a kernel dev from Red Hat, writes about Xen here and here.

That's interesting that Xen patch is much bigger than OpenVZ patch, and very intrusive (this is unavoidable as I understand; OpenVZ is intrusive as well, especially the resource management part). And they still have a long way to go to become more of a product rather than interesting (and much hyped about) developing technology.

Still, the one goal that OpenVZ, Xen and all the other virtualization software projects and products have in common is to teach people virtualization — what is it, what kinds of virtualization do we have, in what scenarios and how it can be useful etc. etc. On that ground, I wish Xen project good luck.

Up and coming kernel patches?
We all know that the various distro vendors pull a lot of weight in what gets adopted... even if it is only by their own users... but given the fact that SuSE and Red Hat have adopted Xen... makes one wonder how all of this will eventually play out in the mainstream kernel.

I saw an article somewhere that claimed that the Fedora people were helping with the development of OpenVZ but I haven't really seen any confirmation of that anywhere. I do really like OpenVZ.

One of the things that pains me though is that I would like to see all of the various disruptive technologies coming along... be compatible with each other. SELinux vs. AppArmor... and you can't use them in OpenVZ, right? What a shame. It would be nice if all of these things were designed with each other in mind.

I hear that OpenVZ can actually run inside of Xen. That sounds interesting.

I am glad there are competitive projects being developed though... and hopefully... eventually they can co-exist with each other... and perhaps be interoperable.

Re: Up and coming kernel patches?
rsbac is gonna work inside of xen (www.rsbac.org), yet much better than selinux or apparmor.. so why choose :)

We are checking AppArmor right now, hope it will be working in some near future :)
