While mobile and smartphone security is the hot topic of the moment among virtualization security gurus, plenty of other virtualization security topics demand IT's attention right now. At the recent RSA Security Conference in San Francisco, the interest in virtualization security ran high - with good reason. Different IT departments are at different points on their virtualization journeys, of course, and some are still thinking about security in the old physical world terms, analysts say.

Despite years of marketing pressure and products that are simpler to use and more widely available, desktop virtualization hasn't taken off to the extent that vendors and analysts expected even a few years ago.
Despite so many optimistic predictions from Gartner, IDC and other surveys about the growth of cloud computing that they're almost an industry in themselves, there's no better indication of real interest from real companies than spending on a new technology.
The agreement announced this week by VMware and LG electronics will act a proof of concept of VMware's virtualization technology on mobile devices, but may not do either VMware or LG much good otherwise, analysts say.
Microsoft has launched a series of partnerships, functional enhancements and product packages in an effort to make its cloud offerings more attractive to enterprise customers and raise the profile of its Hyper-V hypervisor as a potential ingredient for cloud-based systems.
Rivals Citrix and VMware have taken their battle beyond technology development, even beyond marketing. Now they're working on the imaginations and psychology of potential customers and, to a certain extent, rewriting history.
Within the last ten days, Citrix Systems and VMware have each landed surprise blows in a fight that has heated up from an us-vs.-them platform debate to a real sparring match in the cloud and virtual desktop arenas.
In the wake of an analyst report certifying Citrix's XenDesktop 4.1 as the only product that fully satisfies all the criteria for enterprise-class desktop virtualization, Citrix Systems has come very close to conceding it will remain an also-ran in the market for virtual servers.
Cloud computing is famous for being a metaphor instead of a technology, but that metaphor is increasingly hard for non-techies to understand. Many variations of cloud have emerged that have little to do with the initial vision that sparked interest-- a public cloud with burst-up capability on demand.
Despite predictions that cloud computing will change the economics and strategic direction of corporate IT, the cloud's greatest impact so far has been in focused, often small projects that owe little to visions of complex, enterprise-class, computing-on-demand services, some users and analysts say.
Facing strong concerns about control and security, the cloud-computing trend has drifted somewhat-- away from the notion that all computing resources can be had from outside, and toward a vision of a data center magically transformed for easy connections to internal and external IT resources.
Desktop virtualization has a predicted growth curve that leaves much of the PC and IT services industries smiling: Yet none of the technologies or service providers promising to offer hosted virtual desktops are ready to step into key roles in enterprise IT infrastructures, according the same well-respected analysts who set the server virtualization market on its ear with a similar conclusion last year.
There are few ways a CIO can look better than by walking in to the CEO's office to offer a sophisticated technology service that answers a desperate business need without requiring large capital expenses or delays before implementation.
It might have been the rage in 2006, but interest in green IT drooped along with the economy during the last two years, analysts say.
Most CIOs have had to deal with rogue business units - parts of the organization that, for one reason or another, can stave off any attempt to modernize, standardize or stabilize its idiosyncratic IT systems, but still need solid data connections to the parent company.
