Transparent migration of virtual infrastructures in large datacenters for Cloud Computing.

Cloud-enabled datacenters need advanced support for an integrated management of platform virtualization technologies. The networking infrastructure of large-scale datacenters is implemented according to redundant multi-tiered architectures whose layers operate at Layer 3 of the networking stack. Splitting the network infrastructure of a datacenter in a number of IP subnets, however, creates limits to the migration of Virtual Machines, reducing the possibility for administrators to efficiently balance the load and reduce the energy consumption of the whole infrastructure.
Interconnection of geographically distributed wireless mesh testbeds: Resource sharing on a large scale.

Creating large scale testbeds for evaluating wireless mesh technologies and protocols, and for testing their ability to support real world applications in realistic environments, is a crucial step towards the ultimate success of the WMN paradigm. In this paper we suggest the hierarchical federation of a planetary scale infrastructure, such as PlanetLab, with a number of local OMF-based wireless testbeds as a viable approach towards this goal.

How to install a Windows XP virtual machine using a SATA controller in Virtual Box

SATA controllers show better performance in comparison to the IDE ones, even in emulated environment like the Virtual Box's one. To create a VirtualBox virtual machine that uses an emulated SATA controller you can just specify the controller type in the virtual machine description, enable ACPI and IOAPIC, and all should work!
How to make VirtualBox's VM screen resolution independent from the host machine resolution

Some months ago I was playing around with ORACLE Virtual Box for one of my works. The work was a server installation for a first virtualization evaluation: the interested company decided to try virtualization in an unobtrusive way, starting smoothly, using an existing os installation.
