Parallels Server debuts on Apple Xserve; supports 50 Operating Systems

Released in a beta, Parallels Server from SWsoft allows multiple copies of Mac OS X Server 10.5 to run on Mac Pro or Xserve computers.

The software also runs on Windows- or Linux-based servers, and can be used either with the Parallels lightweight hypervisor or in "bare metal." With the hypervisor, virtual machines operate with a primary operating system; in "bare metal," virtual machines run independently without being dependent on a host operating system.

Support for 50 Operating Systems

The company said that Parallels Server is the only virtualization product that allows administrators to choose the hypervisor or bare-metal option during installation. Parallels Server supports more than 50 different guest operating systems, including Windows Server, Red Hat Linux, SUSE Enterprise Linux, Sun Solaris, and Mac OS X Server.

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...
