Intel, AMD: Vmware VMotion about to get more agile!

That is what Intel and AMD think.

According to Tim Mueting, AMD virtualization solutions manager, the company is working with VMware Inc. to help the company take advantage of facilities within AMD's chips to mask differences between CPU generations, and therefore enable the safe live migration of VMs between servers running different AMD processors.

Mueting said he expects the functionality to be available "within a year, but maybe even sooner than that," and will work with Opteron Rev E and Rev F, AMD's forthcoming quad-core "Barcelona" and beyond.

In a similar vein, Intel in June announced a new feature for its forthcoming Xeon processor, code-named Penryn. The feature, called FlexMigration, will enable live migration between different generations of Intel processors.

Intel and AMD's work won't fix VMotion's limitations per se -- it will merely lay the foundation for VMware and others to take advantage of capabilities within the chips to manage differences in instruction sets. Nor are there any efforts underway to enable live migration between Intel and AMD processors.

"Our goal is to create flexibility, based on what [the customers] purchase today, for future generations of Intel processors," said Jake Smith, part of Intel's Advanced Server Technologies team. "We do not do cross-company enablement."

Security: VMware Workstation 6 vulnerability

vulnerable software: VMware Workstation 6.0 for Windows, possible some other VMware products as well type of vulnerability: DoS, potential privilege escalation I found a vulnerability in VMware Workstation 6.0 which allows an unprivileged user in the host OS to crash the system and potentially run arbitrary code with kernel privileges. 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...
