it happens only with Power8 compat(HPT) guests, and specifically older guest kernels, in this case 3.10.0-957.5.1.el7.ppc64le.

this upstream commit should possibly fix it, https://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc.git/commit/?h=kvm-ppc-next&id=46dec40fb741f00f1864580130779aeeaf24fb3d
