Lippis Report: A new era in networking with virtualization

The three pillars of IT computing, networking and storage have always been embraced in an odd dance of shifting functionality responsibility as Moore’s Law continues to break down, blur and redistribute lines of responsibility across the three pillars in an effort to increase application performance. For example, networking has always off loaded tasks that were once done by computers. In fact some of the first routers were DEC mini and micro VAX systems back in the early 80s. This trend continues today with more computer functions such as load balancing, caching, security and certain aspects of computer operations migrating to the network fabric. Access to and configuration of storage has gone through huge changes over the years, thanks to networking, with the introduction of Network Attached Storage (NAS) and Storage Area Network (SAN). Computing functionality, applications acceleration, storage access and many other functions have shifted into the network fabric. The latest shift is network virtualization where better utilization, increased flexibility and application performance is promised in the data center and the overall enterprise.

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...
