Citrix marches ahead with its Data Center Strategy; Leaves Cisco et al behind

When Citrix first acquired XenSource it wasn't immediately obvious how the company's NetScaler line of application accelerators was going to be relevant to the deal.
But this week Citrix took some folks by surprise with the announcement of a new MPX line of accelerators that leverages virtualization technology to allow the MPX devices to dynamically provision the server assets in the data center based on the traffic demands that the application accelerator sees on the network.
In effect, Citrix has stolen a march on Cisco's evolving data center strategy be leveraging XenSource software to allow networking devices to manage the rest of the data center. As virtualization continues to evolve it is becoming clearer that the convergence of networking, server and storage assets is going to happen a lot faster than previously thought.
This will present some management challenges for senior IT people as fewer IT people are required to manage a broader array of devices. The immediate upside is lower labor costs but in the short term there is likely to be some political jockeying for control between the networking, server and storage camps.

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...
