Motorola announced that it’s investing in VirtualLogix, a maker of virtualization software for communications devices and infrastructure equipment. This shows that virtualization is still a hot investment trend, and not just in the core desktop and server markets.

Terms of the investment have not been disclosed. VirtualLogix’s technology does real-time virtualization, or the ability to split a computing platform into different partitions and shift from one partition to another quickly. While companies like VMware do this for corporate servers and desktops, VirtualLogix does it for communications devices (cell phones, other devices) and infrastructure.

In the mobile space, it allows users to move applications from desktops to devices easily. And it allows one device to run multiple operating systems. It also promises to improve the quality of service and security as well. That’s important in an increasingly open mobile world.

Motorola joins VirtualLogix’s current investors Atlas Venture, Cisco, DFJ Esprit, Index Ventures, Intel Capital and Texas Instruments.
