Hi, I'm currently testing cpu hotplug with a windows 2012R2 standard guest,
and I can't get it too work. (works fine with linux guest). host kernel : rhel7 3.10 kernel qemu 2.2 qemu command line : -smp cpus=1,sockets=2,cores=1,maxcpus=2 Started with 1cpu, topogoly is 2sockets with 1cores. Then qmp# cpu-add 1 I can see a new cpu is windows device manager, and event log in the device said that it's online. So it should be ok, but. I can't see new processor in taskmanager or perfmon. (I had tried to relaunch them to be sure.). So, it is a windows bug ? Does I need to do something else ?
