Virtualization shift: Prime Time for Open source?



Amy Newman, from ServerWatch reporting...

Shifting gears a bit ...

Open source virtualization options are on the rise. While Xen has long held court as the media darling, it's not alone anymore. SWsoft, the force behind the OpenVZ project, which is now the basis for Virtuozzo increased its stronghold. (Virtuozzo competes with VMware, despite taking a different approach to virtualization.)

And in related news on Monday, Qlusters announced an increase in its virtualization capabilities and Xen support for openQRM, its open source data center provisioning and management software for physical and virtual environments.

The open source license is pretty much where the similarities end, however.

openQRM is licensed under the Mozilla Public License and is designed to integrate with Xen and VMware, while OpenVZ is developing the environment itself.

"The philosophy behind the Qlusters architecture is that it is open and can integrate with components already there," Ofer Shoshan, founder and CEO of Qlusters, told ServerWatch.

As such, the latest release of openQRM is designed to enable administrators to change the memory consumption of a Xen partition on-the-fly while making it possible to add, remove and assign virtual machines to specific physical units on the host without restarting the system.

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...
