My colleague, Ales Rosina, Microsoft Student Partner from Slovenia recently wanted to have Windows7 as a virtual operating system inside VirtualPC, for quick access, testing… [...]
How to add new virtual machine in Virtual PC?
Monday, May 18th, 2009After installing Windows 7 RC, and new Virtual PC that comes as an upgrade, I was a little bit confused, and surprised.

Microkernelized hypervizor
Thursday, December 4th, 2008In the last post from the series “Virtualization types”, I’m gonna explain you microkernelized hypervizor, model that is used in Windows Server 2008 for server virtualization.

Wednesday, December 3rd, 2008In the monolithic model of Type 1 virtualization, the hypervizor has it’s own drivers for accessing the hardware beneath it. Guest OSs run in VMs on the top of the hypervizor, and when a guest needs to access hardware it does so through the hypervizor and it’s driver model. Typically, one of these guest OSs [...]
