Application Virtualization: Why applications are so crucial

I like reading chuck's blog. I do that primarily because he is focused and addresses issues that we all tend to forget in all the hullo-bullo of virtualization game.

No IT user wants support hassles.

So it's routine to ask any OS vendor, "does application vendor X support your operating environment?". True for all the UNIXes. And true for server/desktop virtualization.

Now, it doesn't matter if the application in question works perfectly; the real question is that -- if there's a support problem -- will the ISV in question will step up and fix the problem?

I think there are two reasons why the answer will usually be a rather unclear "well ...", especially for things like VMware.

First, it costs more for the ISV to support an additional environment, and unless they can see clear incremental revenue (e.g. licenses, maintenance, etc.) it's hard to make an internal case.

Of course, customers beating you over the head helps a bit to move that discussion along.

Second, I think no major ISV really wants interloping vendors below them in the stack. Look at Oracle's repeated efforts to commoditize everything below the database: remember "bare metal" Oracle? Or SAP's preference for Linux? Even Microsoft doesn't have a strong incentive to let others in here.

Ask any ISV of any size a direct question: do you support VMware? -- and you'll get a very contorted answer as a result. It has absolutely nothing to do with technical realities and everything to do with business models and strategic advantage.


Anyways read his insightful post.

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...
