VMotion and VLAN Security

Xensploit, as it’s called, is the recently demonstrated exploit that allows virtual machines (VMs) that are “in flight” during a live migration (XenMotion in Citrix XenServer, VMotion in VMware ESX Server) to be manipulated. If you haven’t yet read the PDF that describes Xensploit, I highly encourage that you take a look at it. It’s very enlightening as to exactly what can be done to an in-flight VM.

Invoke

Yet another VI plugin from Andrew Kutz has been released. This time the plugin is Invoke, which is designed to allow third-party applications to be invoked (hence the name) from within the VI Client while leveraging the VI Client’s existing authentication.

I Love It, But It's Not Available

A friend of mine at Network Appliance was one of the presenters last year at VMworld 2007 for the now-famous presentation that showed a solution from Network Appliance where 100 VMs are created in just a couple of minutes. It’s great technology that is extremely useful in exactly those kinds of situations. I love it.

Nailing Our Colours to the Mast

How many readers out there have ever found themselves at a dinner with some professional colleagues? Probably quite a few of you. I had dinner with some SEs from various other resellers and some vendor representatives tonight. It’s a fairly common occurrence, right?

Moving Past the Hype

It’s only natural, I suppose. When wireless networking started to become popular, it was decried as insecure and everyone was warned against using it. When mobile computing started to take off, it was proclaimed a terrible security risk, and organizations were warned against it. And now it’s happening with server virtualization. Of course, since VMware is the lead player in this realm, they are the ones with the target on their back.

VDI Announcements at VMworld Europe 2008

Back in 2006, I speculated that one day VMware would allow hosted virtual desktops to be “checked out” and used offline. Lo and behold, one of the announcements that has come out of VMworld Europe 2008 is just that very thing (quoting from VMware’s web site):

VI Plugins Expose a Problem

In his work developing VI plugins, Andrew Kutz discovered a potential security flaw. Quoting from the e-mail he sent me:

Vendor Responsiveness

In early January, I wrote an article about how unimpressed I was with VMware’s Remote CLI, the tool released along with ESX Server 3i and—at the time—the only way to perform a Storage VMotion operation. Since that time, of course, a Storage VMotion plugin for the VI Client has been released.
