Personal Computing as a Collection of VMs?

There appear to be basically two views on how virtualization will affect the future development of operating systems and computing environments in the personal computing space. One camp believes that virtualization functionality will be present within the operating system. Whether that virtualization functionality comes bundled with the operating system or is a third-party add-on to the operating system is, quite frankly, irrelevant to this particular discussion. The other camp believes that virtualization will be outside the operating system, perhaps in the form of a hypervisor or thin virtualization layer that resides “below” the OS and governs access to hardware. Again, the discussion of whether this virtualization layer comes bundled with the hardware or comes from a third-party vendor is an interesting discussion (and one that I’d like to have), but is not relevant right at this moment.

SSH from ESX Server to Data ONTAP

By default, the SSH configuration on VMware ESX Server only supports AES encryption types (specifically, AES-256 and AES-128). If you need SSH connectivity from ESX Server to a Network Appliance storage system running Data ONTAP, you’ll need to modify this to support 3DES.

Application Agnosticism

I coined the term “application agnosticism” in the context of the discussion surrounding virtualization and its impact on the future of the operating system. Virtualization proponents, such as VMware, say that virtualization means the end of the general purpose operating system and instead point to the rise of virtual appliances. In the virtual appliance realm, the operating system exists to provide services to the application, and unnecessary components of the operating system are stripped away. This is a good solution in the datacenter, but is it an equally valid approach on the desktop?

VMware Fusion Public Beta

Rumors had been building for the last few days, and in response VMware finally released the public beta for VMware Fusion, the Mac desktop virtualization product. I’d written about my first impressions earlier; now I’d like to share my thoughts on the public beta build.

Changing the IP Address in Solaris 10 U3

Changing the IP address of a system running Solaris (Solaris 10, specifically) is different than a lot of other operating systems out there. Really, all you have to do is just edit a few files and then take the interface down and back up again. However, there seems to be a “gotcha” with Solaris 10. (I don’t know how far back this procedure goes—it is unclear to me if this is new to Solaris 10, or if it extends back to Solaris 8 or 9.)

iSCSI from NetApp to ESX Server

Network Appliance storage systems are becoming more and more visible in VMware deployments due to their iSCSI support and the synergies that are gained when combining VMware’s functionality with the functionality of Network Appliance’s Data ONTAP operating system. I’ll touch on those synergies in a future article, but in the meantime here’s how to configure a NetApp storage system to present iSCSI storage to one or more servers running ESX Server.
