ESX 3i embedded server may pose new challenges for admins?

With 3i, instead of executing scripts directly on the Linux-like console, administrators will have access to a remote command line interface (CLI) from a standalone virtual infrastructure (VI) client to perform old ESX commands, said Raghu Raghuram, VMware vice president of platform products.
But remote CLI allows administrators to invoke only ESX-specific commands, such as those that start with the "esxcfg" string; Linux-specific facilities are not included. That means that "the commands we use to gather information will remain the same but how we invoke them will have to change," said Alistair Sutherland, director of Taupo Consulting, a VMware integrator in Edinburgh, Scotland.

Granted, running scripts in the service console is somewhat of a relic from a previous era, said VMware's Raghuram, even if the practice persists today. "Before VirtualCenter, we had the service console concept, and we used to encourage people to go there," he said. But with the advent of VirtualCenter in 2004, VMware introduced a set of application programming interfaces (APIs) that people can use to interact with ESX hosts, and "that philosophy is still unchanged; both 3 and 3i still connect to VirtualCenter."

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.

Virtualization: GlassHouse hopes to cash in with its IPO!

GlassHouse Technologies Inc. on Tuesday registered to raise as much as $100 million in an initial public offering that, despite the company's financial losses, could prove a hit with investors drawn to its focus on "virtualization" technology. The Framingham, Mass., company offers consulting services for companies that use virtualization software to improve the performance of corporate servers and cut costs in their data centers. GlassHouse also provides Internet-based data storage. "Software-as-a-service," or SaaS, companies and vendors of virtualization products have proved popular among investors in recent years as corporate customers seek alternatives to conventional packaged software. GlassHouse, with roots in both sectors, will test the strength of that interest, said Peter Falvey, managing director with Boston investment bank Revolution Partners. "It will be a bit of a bell weather," he says. "It's not as though it's the 15th SaaS m...
