  "message": "kvm: x86: Save/restore FPU OP, IP and DP\n\nThese FPU states are properly maintained by KVM but not yet by TCG. So\nfar we unconditionally set them to 0 in the guest which may cause\nstate corruptions, though not with modern guests.\n\nTo avoid breaking backward migration, use a conditional subsection that\nis only written if any of the three fields is non-zero. The guest\u0027s\nFNINIT clears them frequently, and cleared IA32_MISC_ENABLE MSR[2]\nreduces the probability of non-zero values further so that this\nsubsection is not expected to restrict migration in any common scenario.\n\nSigned-off-by: Jan Kiszka \u003cjan.kiszka@siemens.com\u003e\nSigned-off-by: Avi Kivity \u003cavi@redhat.com\u003e\n",
