[Novalug] Win 7 64 painfully slow in KVM on Ubuntu 12.04

I just ran into basically the same exact situation. I installed Win7 x64
in a KVM VM on an Ubuntu 12.04 host and saw the same symptoms...extremely
slow installation, slow performance after installation, etc. I didn't
spend a whole lot of time trying to figure it out - I ended up going back
to VirtualBox, which works fine. I initially tried the VirtualBox that
comes with Ubuntu 12.04, but the Win7 installation kept failing. I got
the latest version directly from Oracle and Win7 installed fine. (This
particular issue might have something to do with my Dell-branded Windows 7
install?)
