KVM on Fedora11
I've been a VMWare Workstation user for years and have generally been pretty happy with it; but it is significantly slower than bare metal, especially when it comes to disk i/o. One of my responsibilities for work is creating and maintaining a custom Fedora distribution. This requires building new rpm packages and then creating a livecd iso for the install of the system. Lots of disk i/o involved in reading and creating the disk image meant that I was running Fedora9 as my native desktop.
