Application Virtualization: Developers need to participate in this convegence!

When an application that hasn't been certified to run on virtual servers encounters technical issues that prevent it from working properly, a user can be left in a bind if none of the involved parties -- the virtualization or operating system vendors, or the ISV -- is willing to step up and fix the problem.

Such situations can result in "a lot of finger-pointing, which is what the user really wants to get around," said Christopher Voce, an analyst at Forrester Research Inc.

The support issue hasn't come to the fore yet because early virtualization adopters have mostly been large enterprises with sufficient clout to demand personalized help from reluctant software vendors, said IDC analyst Michelle Bailey. "The basic message is, 'Either support me or I'll find some other ISV that will -- or maybe I'll go open-source,'" Bailey said.

But she added that as virtualization software trickles down to smaller and less cutting-edge companies, those users "will be more conservative in their approach and will be looking for compliance [from vendors] upfront."

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.

OS Virtualization comparison: Parallels' Virtuozzo vs the rest

Virtuozzo's main differentiators versus hypervisors center on overhead, virtualization flexibility, administration and cost. Virtuozzo requires significantly less overhead than hypervisor solutions, generally in the range of 1% to 5% compared with 7% to 25% for most hypervisors, leaving more of the system available to run user workloads. Customers can also virtualize a wider range of applications using Virtuozzo, including transactional databases, which often suffer from performance problems when used with hypervisors. On the administration side, customers need to manage, maintain and secure just a single OS instance, while the hypervisor model requires customers to manage many OS instances. Of course, the hypervisor vendors have worked hard to automate much of this process, but it still requires more effort to manage and maintain multiple operating systems than a single instance. Finally, OS virtualization with Virtuozzo has a lower list price than the leading hypervisor for comme...
