In a slightly strange “didn’t they already have Xen in the kernel” kind of way, Novell has certified Suse Linux Enterprise Server as a “perfect guest” running on Citrix XenServer, allowing joint support of the combined solution. The deal is asymmetric (it wouldn’t really make sense to run XenServer on SLES) but it reflects an open approach characteristic of the way Novell operates, in embracing the reality that customers will want to use one of a number of possible hypervisors, and that Novell has to get along with everyone. In return Novell is starting to push it’s PlateSpin Recon product through the Citrix channel.
Brad Hedlund of Cisco asked the question, should the physical network security policy be different than the virtual network security policy? The answer is obviously no, but why are they treated separately? I and other have pushed the concept that to gain performance, redundancy, and security that you should use multiple network links to your virtualization host to separate traffic. However, does this really give you security?

Well the worse kept secret in virtualisation is now finally out in the open, have a read of VMware ESX to ESXi Upgrade Center:Planning your Upgrade to the next-generation hypervisor architecture where they state that “In the future, the superior architecture of ESXi will be the exclusive focus of VMware’s development efforts. This means that not only will the ESXi hypervisor superceed the classic ESX hypervisor in a new version of vSphere; what the time scale is, is currently unknown however it is most likely to be vSphere 5 or whatever they decide to call the next major release. What is more interesting in statement is that VMware expects their customers to upgrade their existing installations of vSphere based on the ESX hypervisor to the new ESXi hypervisor.
I had an interesting conversation with Vizioncore yesterday about how backup is not as much a decision about what software to use but what process to use. In addition, this process needs to be considered from the very beginning of your virtualization architecture. With the quantity of virtual machines being used today by the SMB and Enterprise customers, the backup window has grown to nearly an all day event. What you say? An all day event? My backups happen with the window I set.
Those of you who attended VMworld this year will remember the stack of servers and storage on display happily serving VM’s to the vistors, exhibitors and Staff at the conference, well one of the key components of that stack was provided by Xsigo. Their product the I/O Director offers signficant savings in large environments by effectively virtualising the I/O stack. I am not going to go into the ins and outs of I/O virtualization in this article. Well it now appears that they are expanding their partnerships.
There has been a rumour that VMware circulating that are going to move to a per VM Guest licensing model rather than the traditional Host based licenses. Well it looks like the first move to this has been taken
On January 25th 2010 VMware reported earnings for the fourth quarter of 2009 and for the full year of 2009. While we are not a financial analysis site focused upon earnings and stock prices, there is important information contained in these earnings numbers about the success of VMware.
VMware has just announced the End of Availability but not End of Life (EOL) for some of its pre-vSphere ESX products (Announcing End of Availability), specifically all but the latest releases of ESX 3.x and vCenter 2.x however, it has dropped availability for the ESX 2.x products completely.

I was privileged to speak at the 3rd Annual South Florida ISACA WoW! Event with Robert Stroud, Alan Shimel, and other great speakers. What I discovered from this conference is something I have feared for quite a number of years. Compliance actions are not continuous but often only enacted when the auditor shows up at the door. Secondly, very few auditors raised their hand when I asked if they are working with Virtualization or have customers that virtualize, this was quite a surprise.
