Hi, This series implements 3 Spectre related PowerPC features that were added back in QEMU 2.12: - CFPC: Cache Flush on Privilege Change - SBBC: Speculation Barrier Bounds Checking - IBS: Indirect Branch Speculation These options aren't much of a problem for users using latest hardware and guests with recent Linux kernels. Users with outdated hardware/firmware or trying to run AIX guests/guests with older kernels, however, will need to fine tune these options because QEMU defaults won't work. Instead of making users rely on <qemu:commandline> elements to hardcode the options in the XML, let's support them in Libvirt.
