Intel IT tested servers based on select Intel multi-core processors to analyze the potential role of each in Intel’s data center server virtualization strategy. Each server provided significant potential benefits in performance, power consumption per workload, and operating costs over older servers running non-virtualized workloads. The server based on the Quad-Core Intel® Xeon® processor 7300 series showed the greatest scalability and used the least power per job when running large numbers of virtual machines (VMs), and proved suitable for achieving high consolidation ratios in a busy enterprise data center.Check out their Whitepaper.
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.
