In addition this update backports support to passthrough the new md-clear CPU flag added in the intel-microcode update shipped in DSA 4447 to x86-based guests. For the stable distribution (stretch), these problems have been fixed in version 1:2.8+dfsg-6+deb9u6. We recommend that you upgrade your qemu packages.
