Hi all,

I tried to use "xl vcpu-set" to change the vCPU number of VMs in Xen
4.4-unstable and had the following errors.

libxl: error: libxl_qmp.c:289:qmp_handle_error_response: received an
error message from QMP server: Unable to add CPU: 0, it already
exists.

CPU hotplug is enabled in the guest OS.

Thanks.
