Mickael Bailly has created a 5 part tutorial regarding his virtualization setup using RHEL5, Xen and GFS. It will be an interesting read for anyone who hasn’t used or studied Red Hat’s recent Xen release:
Enjoy.
Update: Unfortunately this presentation is offline. If anyone knows of an alternate location let me know, since I don’t host it I don’t control whether it’s available or not.

It looks like RHEL4 Update 5 is now out in some form. I didn’t see any official announcement yet but last night my internal yum repository got updated with a pile of RPMs which got me curious.
Anyway, whether Update 5 is official or not you can now grab an official Xen domU kernel for RHEL4 right from Red Hat.
Kernel errata package document is RHBA-2007-0304. You can grab either
kernel-xenU-2.6.9-55.EL.i686.rpm or kernel-xenU-2.6.9-55.EL.x86_64.rpm.
Update: Red Hat’s release notes are here.

This week Red Hat made available a BETA of their 5th update to RHEL 4 (we would call it RHEL 4.5).
Most noteable in this release is that Red Hat now includes a kernel that can run paravirtualized on top of Xen.
This will mean that Red Hat shops can jump on paravirtualized Xen virtual machines with relative ease, and quite soon. RHEL 5 can be used for the base of the Xen virtualization solution but all of those virtual machines that your developers use can stick with the tried and true RHEL 4.
Thanks to internetnews.com for the news. See their article for more details.

Yesterday Red Hat offered a press release regarding virtualization in RHEL 5. Red Hat says:
“Customers care about open interoperability and certification for running joint Red Hat and VMware environments,” said Brian Stevens, CTO at Red Hat. “With this relationship, the two virtualization platforms that Red Hat Enterprise Linux will support are the VMware platform and the Red Hat Integrated Virtualization platform that will be available in Red Hat Enterprise Linux 5. The wide adoption of open source is a result of the commitment to interoperability. Support for our joint customers is just one more example of the efficacy of true open source development.”
Red Hat Integrated Virtualization platform means Xen of course, combined with Red Hat’s libvirt and virtualization manager.
The release further states that “Red Hat has already certified VMware Infrastructure as both a certified software application and a certified virtual hardware platform for Red Hat Enterprise Linux.”.

This week Penguin Computing announced the availability of Sycld Clusterware HPC 4. See press release. Penguin’s product page (here), categorizes their software as follows:
Scyld ClusterWare HPC provides enterprises and organizations with a productive, simple and hardware agnostic HPC system enabling administrators to install, monitor and manage the cluster as a single system, from a single node – the Master. Through the Master, thousands of systems can be managed as if they were a single, consistent, virtual system, dramatically simplifying deployment and management and significantly improving data center resource utilization and server performance.
Sounds intriguing.

From Red Hat, Novell Spar Over Xen’s Readiness:
Red Hat executives said the Xen code in the Raleigh, N.C., Linux distributor’s upcoming RHEL 5 works, but they won’t advise enterprise customers and ISVs to deploy it until unfinished business around the API set, interoperability interfaces and Xen’s integration with the Linux kernel are resolved.
An interesting perspective but it still smacks of we’re not ready so Xen isn’t ready. Nothing has stopped Red Hat in the past from patching kernel functionality in that they thought their customers wanted.
Also, from the same article:
At LinuxWorld, XenSource and Virtual Iron said they plan to ship their respective XenEnterprise and Virtual Iron platforms in the next few weeks. They indicated that Xen is ready.
Cnet’s
news.com has this quote regarding XenEnterprise from XenSource:
“It’s going to be generally available next week,” Levine said in a speech here at the LinuxWorld Conference and Expo. The major goal of the software is to make the Xen open-source virtualization software easy to use, an idea reflected in the company’s “10 minutes to Xen” tagline.
Very interesting, generally available means not-BETA in my book. See original article XenSource’s first product due next week for more details.

According to Computer Business Review, Redhat will announce a new version of it’s Enterprise Linux product that allows unlimited use as a virtualized operating system, my bet is for the name to be RHEL 5 VS. We assume this means unlimited use per physical host, otherwise I’ve got a few hundred boxes that I might like to move to RHEL in the near future.
See CBR article here.

Fedora Core 5 is now officially available. Read the official announcement here.
For virtualization folks the highlight of the release is definitely the inclusion of Xen 3 based virtualization.

Redhat today announced it’s “Integrated Virtualization” strategy. In a nutshell Redhat is “working with partners such as AMD, Intel, Network Appliance and XenSource to simplify virtualization deployment for customers”.
Much work is going into ensuring tight integration of Redhat Linux with new chips featuring Intel VT and AMD Pacifica. The particular focus (at least from the news release) appears to be getting Xen fully integrated.
It will be interesting to see where Xen development heads in the next 6 months, there are many things afoot:
- changing xend to use xml-rpc instead of s-expressions (yay!)
- work on simplified virtualization library (livirt) by IBM and Redhat employees
- Xensource’s eventual release of Optimizer and/or their focus on OEM integration with Redhat, SuSE and others
Read original press release here.
Also see the newly announced site openvirtualization.com (currently a redirect to Redhat) hopefully this site develops into a great source of information.
