Qlogic and VMware extend partnership; demo on migration with Virtual HBA


QLogic Corp. , a leader in networking for storage and high performance computing, today announced it is first to demonstrate VMware virtual machine migration using QLogic® virtual HBA technology. Live migrations allow IT managers to take down a working server, upgrade the operating system or apply patches, and then bring it back up again while users continue to access applications on the server. The demonstration at VMworld is part of a collaboration between QLogic, VMware and its Community Source program to complement server virtualization software with hardware-assisted virtualization. The hardware-assist virtualization technology inside QLogic SANblade® HBAs eliminates the need for ESX administrators to reconfigure SAN functions after live virtual machine migrations.

“Customers are now consolidating more VMs onto a single, physical server,” said Greg Schulz, founder and senior analyst, The StorageIO Group. “NPIV technology helps link worldwide port names to individual virtual machines to enable performance monitoring on a per-VM basis, as well as seamless live migration of VMs without compromising SAN and data integrity not to mention eliminating the need for timely and complex SAN reconfigurations such as zoning or LUN masking changes.”

“NPIV technology for Fibre Channel HBAs provides key benefits such as dynamic provisioning of SAN configuration settings and enhanced quality of service (QoS), thereby enabling SAN administrators to extend their SAN best practices to virtualized environments,” said Amit Vashi, vice president of marketing, QLogic Host Solutions Group.

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...
