Virtualization shift: Prime Time for Open source?



Amy Newman, from ServerWatch reporting...

Shifting gears a bit ...

Open source virtualization options are on the rise. While Xen has long held court as the media darling, it's not alone anymore. SWsoft, the force behind the OpenVZ project, which is now the basis for Virtuozzo increased its stronghold. (Virtuozzo competes with VMware, despite taking a different approach to virtualization.)

And in related news on Monday, Qlusters announced an increase in its virtualization capabilities and Xen support for openQRM, its open source data center provisioning and management software for physical and virtual environments.

The open source license is pretty much where the similarities end, however.

openQRM is licensed under the Mozilla Public License and is designed to integrate with Xen and VMware, while OpenVZ is developing the environment itself.

"The philosophy behind the Qlusters architecture is that it is open and can integrate with components already there," Ofer Shoshan, founder and CEO of Qlusters, told ServerWatch.

As such, the latest release of openQRM is designed to enable administrators to change the memory consumption of a Xen partition on-the-fly while making it possible to add, remove and assign virtual machines to specific physical units on the host without restarting the system.

The issue is in the vmstor-60 driver, which is supposed to mount VMware images within the host OS. When sending the IOCTL code FsSetVoleInformation with subcode FsSetFileInformation with a large buffer and underreporting its size to at max 1024 bytes, it will underrun and potentially execute arbitrary code.

Virtualization: GlassHouse hopes to cash in with its IPO!

GlassHouse Technologies Inc. on Tuesday registered to raise as much as $100 million in an initial public offering that, despite the company's financial losses, could prove a hit with investors drawn to its focus on "virtualization" technology. The Framingham, Mass., company offers consulting services for companies that use virtualization software to improve the performance of corporate servers and cut costs in their data centers. GlassHouse also provides Internet-based data storage. "Software-as-a-service," or SaaS, companies and vendors of virtualization products have proved popular among investors in recent years as corporate customers seek alternatives to conventional packaged software. GlassHouse, with roots in both sectors, will test the strength of that interest, said Peter Falvey, managing director with Boston investment bank Revolution Partners. "It will be a bit of a bell weather," he says. "It's not as though it's the 15th SaaS m...
