Virtualization boosts FC SAN's growth

To exploit the "peak" years of double-digit Fibre Channel growth -- which Villars projects will continue through 2009 -- switch makers are going to have to enhance the ability of users to work with virtual technologies. "Part of the value of server virtualization is the whole mobility angle," he said, "so that [you] can take an application running on one server and then -- because of a failure or planned downtime or performance change -- nondisruptively migrate it to another server."

Villars recommends that storage administrators make sure that network rules and SAN connectivity rules agree with each other. To date, Villars said, "that's proven to be one of the big disconnects -- VMware wanting the network to look one way, and the people running the SAN wanting to configure it in a different way, because it gives them some assurances about protection or load-balancing."

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...
