I've stumbled on WS2016 hang when trying to list memory map in QEMU. Steps to reproduce: qemu-system-x86_64 -monitor stdio -enable-kvm -m 1G ws2016x64.img wait till guest boots and execute in monitor (qemu) info mem
qemu will hang while printing mappings, consuming 100% cpu and not responding to ^C. I've also tried with old (2.8) and current qemu master and today's upstream kernel where it also doesn't work but WS2012R2x64 guest works just fine. PS: CCing KVM list as the issue happens only when KVM is enabled.
