[Qemu-devel] Windows 10 guest hang during 'info mem'

[Igor Mammedov]

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.
