Embedded Hypervisor: "Bare Iron" songs

OK, so you got the drummer, lead guitarist, bass guitarist, vocalist, so what do you do? You grunge it all out.

VMware has released its first embedded hypervisor.

The new ESX Server 3i runs directly on the server's hardware (refered to as 'bare iron') without requiring an operating system. Users run their virtual machines directly on this software.

Virtualisation users previously had to install their own operating system and install virtualisation software on top of that.

Measuring only 32MB, the embedded hypervisor is 90 per cent smaller than the average operating system and virtual machine combination, VMware claimed.

Its smaller footprint renders it more secure and more stable than mainstream operating systems which offer many features that are needless to the average user, VMware chief executive Diane Greene argued in her opening keynote at VMworld in San Francisco.

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...
