Hi, I try to hot add vcpus to a windows server 2012r2 virtual machine on RHEL 7.4 platform. But Task Manager didn't show extra processors I hot added though they appeared in Device Manager. Actually, I need to require reboot the vm to make processors hot Added appear in Task Manager. Is there some problem with redhat qemu? Why the processors I hot-added didn't online automatically? I don't know if I ask the right person or in a right mail list, apologize first if I bother you.
Thanks, Zongyong Wu
