Why are there two upstream source trees shown?

Created by Al Stone

Due to problems at kernel.org, the mirror of the original upstream git tree (the one called lp:~ahs3/kvm-guest-drivers-windows/upstream) is not currently being maintained as the authoritative source. It may be restored at some point, but that's entirely up to the upstream developers. Right now, it just doesn't exist.

In the meantime, the git tree has been made available on github. The tree called lp:~ahs3/kvm-guest-drivers-windows/upstream-github is a mirror of that more recent source.
