Storage vendors beginning to get unconfortable with VMware

But as VMware adds features to its file system, there's growing suspicion among storage vendors that the company is trying to move storage system value-adds into its Hypervisor. Some storage vendors think that VMware is stepping on their toes, especially when it comes to Storage VMotion, a feature in VMware ESX Server version 3.5 that migrates the back-end storage attached to virtual machines.

It's a matter of virtualisation vendors like VMware "looking for ways to add value" as the virtualisation becomes commoditized, says Bruce McCorkendale, distinguished engineer in the office of the CTO for Symantec Corp.

As more companies virtualize their server environments, users who once struggled with running multiple operating systems will now struggle with running physical and virtual servers, and in some cases, with running multiple hypervisors.

This is where Symantec sees the value proposition for its vendor- and platform-agnostic storage, security and server management software. "We've been helping users do storage management and high availability in heterogeneous environments for a long time," McCorkendale said. "For [another vendor] who hasn't been doing it that long, going from zero to Symantec will take quite a while."

If it sounds like McCorkendale is drawing a line in the sand, it's because he is. VMware may insist it's not trying to compete with storage vendors. But, McCorkendale says, "They are. The question is how well they're going to be able to compete."

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...
