== Xenial ==
Since Xenial fulfills those requirements, I'd think the QEMU patch would be backportable without too much effort. I haven't look at the code so take this with a grain of salt.
== Trusty ==
Trusty doesn't meet the requirements so addressing it there would probably be more involved and maybe not worth the time investment and the stability risks.
