@sullrich i haven't shipped drivers myself but the only ways i am aware of overcoming is either through something like ctf data to check for abi changes or compile and ship drivers for each supported minor kernel release( in freebsd case the kmods repo)
@TheHackersNews it would be a huge deal if it affects kvm itself because first KVM's codebase is significantly small and second it would affect almost all the major clouds no matter what VMM they use
