How soon before we get to the point where we have virtualization for everyone?
Virtualization is definitely headed toward ubiquity. At VMworld [in September] we announced our embedded hypervisor, the ESX3i, and many of the major x86-based hardware vendors announced they will ship servers with an embedded ESX server in them. Anything that's virtualized has more flexibility, better utilization, and stronger reliability and security properties. I'd say there's still some hardware-assist work to be done. We estimate that about 90 percent of applications today belong in virtual machines. Once the final hardware assist is there from the processor and peripheral vendors, all applications will run in virtual machines. What it gives you is this single way to manage your software and manage it completely separately from your hardware.

There's some industry talk about the eventual emergence of a complete virtualization system. What's your vision for that?
Once you have a comprehensive virtual infrastructure in place where you buy servers already virtualization-enabled, where you're running a VMware infrastructure, then you can have hot-pluggable machines. So if you're running out of capacity you can add servers and through VMware-or some virtual infrastructure-the system will automatically detect that you just added new resources and bring them all online and make them available for applications. With things like our VMotion technology you can automatically move running applications around. Or if you want to take something out of the system to service it, the systems will automatically move the applications off with no interruptions because you have a fully distributed system infrastructure running. A virtual infrastructure really takes all your hardware, server storage and network resources and pulls it all together so you can run it as a single system.



Well in two year, I'd say.

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...
