[Qemu-devel] CPU hotplug on Windows 2016 as guest

Hi guys,

I'm just trying Qemu 2.7 and 2.8 and Windows 2016 as guest and cpu
hotplug doesn't seem to be working. CPU appears on qemu device tree, but
doesn't appear inside the guest (nor control panel, performance monitor
or device manager)

Anyone going through this?

It's MS regression we've found in September,
workaround is to remove wrong driver bindings in the guest
see: https://bugzilla.redhat.com/show_bug.cgi?id=1377155#c17

And complain to MS support so that they'd fix it.
