Red Hat talks the expansion of operating system-based virtualization


Red Hat NewsSearchEnterpriseLinux.com is prepared to go into LinuxWorld next week with guns blazing, but we’re not going in so fast as to not post some preview coverage beforehand. Over at our conference coverage page, LinuxWorld 2007: News, trends and tutorial coverage, you can see what’s live and get a feel for some of the trends that have materialized thus far.

One of major trends touched upon before the conference even begins is virtualization. It’s not just for consolidation anymore, as many of you undoubtedly know already. Red Hat was one of the first Linux vendors to get something on this topic into my mailbox this week (Novell was the other), and it was interesting to see what they have up their sleeves right now.

According to Red Hat’s Emerging Technologies Team, the company is finally starting to see how its customers are actually going to use virtualization ( a brief warning; after reading these you will have the uncanny feeling that Red Hat can do no wrong with virtualization):

* Customers are quickly realizing that Red Hat Enterprise Linux virtualization, which is provided as part of the base product for no additional cost, works really well. It’s stable, mature and easy-to-mange.
* Para-virtualization, available for Red Hat Enterprise Linux 4 & 5 guests, delivers performance that is close to bare-metal. So why not use it everywhere?
* Full-virtualization performance is dependent on the application – so it needs to be deployed with some care. But, enhancements due at the end of the year will close the gap with para-virtualization significantly. This will make Red Hat Enterprise Linux a terrific virtualization platform for any Windows system, with better storage virtualization and driver support than is available with proprietary virtualization products, at much lower cost.
* Consolidation frees up systems that can be redeployed as fresh Red Hat Enterprise Linux servers to handle rapidly growing IT requirements.
* The exciting uses of virtualization lie beyond consolidation – they are in areas of high availability, operational flexibility, resource management and enhanced development environment.
* Red Hat Enterprise Linux Advanced Platform, with its comprehensive storage virtualization capabilities, can save you from having to purchase lots of other expensive software.
* Live migration, which is also included in the base product, is the key to flexibility.

We’ll know more after a briefing or ten next week at the show to get a good, objective look at these various points. For now, however, I suggest you check out our preview coverage and wait for the live stuff as it trickles in from the show.
