Red Hat announced Red Hat Enterprise Virtualization Hypervisor

February 23, 2009 by Kris Buytaert Leave a Comment

Today RedHat sent out 2 press releases obviously in an attempt to get Virtual visibility during VMWorld. Europe, The biggest news in those 2 press releases is the announcement of the Red Hat Enterprise Virtualization Hypervisor, or the RHEV . Red Hat announced their new strategy regarding to Virtualization which they call the Red Hat Enterprise Virtualization portfolio of products.

First in the Lineup is

Red Hat Enterprise Linux: Red Hat’s strategic direction for the future development of its virtualization product portfolio is based on KVM, making Red Hat the only virtualization vendor leveraging technology that is developed as part of the Linux operating system. Existing Xen-based deployments will continue to be supported for the full lifetime of Red Hat Enterprise Linux 5, and Red Hat will provide a variety of tools and services to enable customers to migrate from their Red Hat Enterprise Linux 5 Xen deployment to KVM.

Well, we already knew that, given the fact that Fedora is heading KVM-wards and that they have to support Xen in Red Hat Enterprise Linux, for the full life cycle of RHEL 5, therefore at least till 2014
KVM will enter the RHEL product line as part of RHEL 5.4, due to be released later this year
RedHat is also announcing Red Hat Enterprise Virtualization Manager for Servers

A new, richly featured virtualization management solution for servers that will be the first open source product in the industry to allow fully integrated management across virtual servers and virtual desktops, featuring Live Migration, High Availability, System Scheduler, Power Manager, Image manager, Snapshots, thin provisioning, monitoring and reporting. Red Hat Enterprise Virtualization Manager for Servers will be able to manage both Red Hat Enterprise Linux 5 hosts, as well as the Red Hat Enterprise Virtualization Hypervisor

a framework based on LibVirt and Red Hat Enterprise Virtualization Manager for Desktops ,

A new management system for virtual desktops that will deliver industry-leading VDI cost-performance for both Linux and Windows desktops, based on Qumranet’s SolidICE and using SPICE remote rendering technology.

With confirmation that the Qumranet code will be open sourced just as RedHat has done with all their other products so far.

And last but not least RedHat is launching a new standalone hypervisor : Red Hat Enterprise Virtualization Hypervisor

Which is

KVM unbundled from RHEL, in a package dubbed RHEV-H(ypervisor). RHEV-H is a stateless hypervisor, with a tight footprint of under 128MB, which presents a libvirt interface to the management tier. Enterprise servers will no longer need to go through an installation process, and will instead be able to boot RHEV-H from flash or a network server, and be able to immediately begin servicing virtual guests. This stateless model drives down OPEX and enables the scalability required by terascale grids, large datacenters and cloud class compute environments.

RedHat also announced that its broad ecosystem of applications tested and certified to run on Red Hat Enterprise Linux are certified to run in a Red Hat virtualized platform with no modifications.

XenServer for Free !

February 19, 2009 by Kris Buytaert 1 Comment

With VMWorld Europe coming up,it seems Citrix is trying to get VMWare out of its warm cozy mansion, it seems they plan to announce next week that they won’t charge anymore for XenServer.

Altough the underlying Xen technology is fully Open source , Citrix doesn’t plan on fully opensourcing XenServer itselve yet. So how will they make their money then you’d ask ? By shipping a new managment framwork that will support both XenServer and the Microschoft Hyper-V platform.

It looks like Citrix is also planning to announce a similar agreement with Micro
soft as RedHat already did earlier this week.

So what will VMWare do as a reaction next week ?

RedHat Moves Closer To Microsoft

February 19, 2009 by Kris Buytaert Leave a Comment

Earlier this week Red Hat and Microsoft announced they were going to work closer together , mainly to ensure Virtualization Interoperability. Both RedHat and Microsoft will join the other’s virtualization validation/certification program and will provide coordinated technical support for their mutual server virtualization customers.

In short this means that Red Hat and Microsoft customers will have the ability to run Microsoft Windows Server and Red Hat Enterprise Linux virtual servers on either host environment with configurations that will be tested and supported by both virtualization and operating system leaders.
The agreements contain no patent or open source license components. There are no financial clauses beyond simple certification testing fees. These are straightforward certification and validation agreements.

The key components of the announcement are as follows:

* Red Hat will validate Windows Server guests to be supported on Red Hat Enterprise virtualization technologies.
* Microsoft will validate Red Hat Enterprise Linux server guests to be supported on Windows Server Hyper-V and Microsoft Hyper-V Server.
* Once each company completes testing, customers with valid support agreements will receive coordinated technical support for running Windows Server operating system virtualized on Red Hat Enterprise virtualization, and for running Red Hat Enterprise Linux virtualized on Windows Server Hyper-V and Microsoft Hyper-V Server.

In a blogpost Scott Crenshaw writes
“Of course, it is also big news because it is rare that these two companies publicly work together. The companies continue to compete vigorously. But virtualization interoperability is very high on customers’ wish lists, and I’m pleased both companies have been able to respond in this cooperative fashion.”

To many the announcement does not come as a big surprise, after acquiring Qumranet, RedHat gained a lot of Microsoft aimed Virtualization knowledge, with this agreement it makes a step towards an even better supported Virtual desktop environment

Release: RedHat Enterprise Linux 5.3

January 20, 2009 by Kris Buytaert Leave a Comment

RedHat just announced the release of RedHat Enterprise Linux 5.3 which is available for immediate download from Red Hat Network. According to the company, with this update to Red Hat Enterprise Linux 5, customers will receive a wide range of enhancements, including significantly increased virtualization scalability.

RedHat lists Increased scalability of virtualized x86-64 environments as it’s prominent new feature:

“This includes the industry-leading ability to support virtual servers with up to 32 virtual CPUs and 80GB of memory. Physical server limits have also been expanded to match the size of today’s latest hardware systems, with up to 126 CPUs and 1TB main memory. New features, such as support for Hugepage memory and Intel Extended Page Tables (EPT), dramatically improve the performance of virtual servers. For customers, these enhancements allow more and larger virtual systems to be configured on today’s powerful servers, thereby reducing costs. Additionally, more devices can be allocated to each virtual server (guest), enabling the virtualization of applications with heavy I/O requirements. ”

Amongst other improvements is support for the Quad Core Intel Core i7 (Nehalem) processors and the inclusion of OpenJDK

Open Source Virtualization Updates

January 7, 2009 by Kris Buytaert Leave a Comment

There is a lot going on in the different Open Source Virtualization projects. From KVM, over OpenVZ , to Xen.

First of all there is the news that Anthony Liguori has included kvm support in the main Qemu development tree. In his blogpost Avi Kivity explains that with the KVM code being merged in Qemu development and integration of new and bigger features will evolve faster.

But now that kvm has been merged, it is possible to make larger modifications to qemu in order to make it fit virtualization roles better. Live migration and virtio have already been merged. Device and cpu hotplug are on the queue. Deeper changes, like modifying how qemu manages memory and performs DMA, are pending.

Then there is some discussion going on about the future of OpenVZ , mainly targeted at licencing and Pete Zaitcev is wondering why Parallels hasn’t officialy modified its COPYING.SWsoft file whic
h mainly tells the world “we’re not serious about going upstream” and which makes him wonder
“Kinda makes LXC more of a fait accompli than it already is or needs to be.” According to the LXH site , the planned Linux kernel version for which LXC should be fully functionaly is 2.6.29.

And last but not least Xen has released 2 minor maintenance releases for their 3.1 and 3.2 branches Xen 3.3.1 and Xen 3.2.3 are now available for download.
