Red Hat’s announcement March 14 of its integrated virtualization push, starring Xen, didn’t take anyone by surprise: Red Hat, along with just about everybody else, has been tooting the Xen horn ever since the fledgling open-source virtualization technology began grabbing headlines almost a year ago.
…
The trouble is that Xen is somewhat early on in its development, and the high rate of change in Xen’s code base will keep the technology out of the mainstream Linux kernel for some time.Red Hat has and will continue to chart its own course with respect to the kernel, diverging from the mainstream where and when appropriate, but Xen’s potential will remain somewhat stunted for as long as it remains in heavy flux…
I’d like to see Red Hat add to its virtualization agenda the OpenVZ project—a GPL’d code base born of SWsoft’s 5-year-old commercial Virtuozzo product, which itself is roughly comparable to the containers in Sun Microsystems’ Solaris 10…
OpenVZ, which also is vying for inclusion in the mainstream Linux kernel, would complement Xen well and has impressed me in the initial testing I’ve conducted.
Ultimately, it might make the most sense for Red Hat to deploy both Xen and OpenVZ. The complementary technologies would be a good counterbalance to the Xen/container combo I expect to see eventually in Solaris…
