Patches for app-emulation/kvm have been removed from the files directory, but all ebuilds for revisions of app-emulation/kvm-70 still refer to them.
Ah yes, when the patches got moved into a tarball, the 70* ebuilds were not updated to download the tarball. Since those old versions are not superior in keywording to the newer versions, it may have been intended to clean them out... anyways, assigning to maintainers.
Removed them. Sorry about that.
