The skip lists here are way too big - stuff like drm_read is common testing not affected by virtio at all - so we really need to isolate the test which is actually breaking things. The way to do this would be to use valgrind to detect where the memory corruption is. VirtIO can be run locally so this is something you can do on your machine.
