Since the kernel team is now investigating the integration of the kernel patches into bionic (the kernel bits are already Fix Committed), we should plan to get the temporary workaround again removed from qemu-kvm. It's hard to time it in a way that the kernel changes are rolled-out and the qemu workaround got removed at the same time. So this could lead to a short time of the qemu mitigation being reverted, but the kernel not yet being released, which would make you need the cap-htm=0ff workaround. But that way it would be much safer that both changes are available prior to the release of 18.04 Bionic. Hence the question (to IBM) is if it would be okay to plan ahead and to get the qemu changes reverted back now?
