The message means that KVM cannot accelerate TCE operations on one of DMA windows, in this particular case - the huge DMA window. Such support is not present in the HostOS as it is not in upstream kernel so there is a message.

Commit 178a7875 tried adding VFIO KVM device but it did not on PPC64 book3s KVM due to a mistake, This - https://git.kernel.org/cgit/linux/kernel/git/paulus/powerpc.git/commit/?h=kvm-ppc-next&id=4b3d173d0440d37534906b6d93c02dfb577c68ce - does add it but it is not in upstream yet.
