[Xen-devel] pvhvm cpu hotplug not working in xen 4.4

[Kristoffer Egefelt <kristoffer@xxxxxxx>]

Is xl vcpu-set supposed to work with pvhvm in xen 4.4?

I’m trying with xen 4.4 rc-6 from git, getting libxl: error: 
libxl_qmp.c:287:qmp_handle_error_response: received an error message from QMP 
server: Not supported

Is some specific version of qemu needed?

Full output:
