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:

Are you using the version tagged/shipped with 4.4-rc6 or one of your own
devising? ISTR Anthony fixing this not so long ago -- which would
suggest a fairly recent qemu was needed -- Anthony???

We might need to wait until 4.4.1 to get back this feature:

I would like this feature to be available, how complicated do you think it is to patch it ?
We don’t have extensive understanding of qemu, but if patching this are unlikely to break other functionality, we would try and fix it now.
What do you think? - I guess the only alternative would be to downgrade qemu from the one shipped with 4.4, which I’d like to avoid...

Xen 4.4.0 has now been released (without the pvhvm vcpu hotplug support in upstream qemu).
.. but the pvhvm vcpu hotplug patches are already in qemu-upstream-4.4-testing tree:
http://xenbits.xen.org/gitweb/?p=qemu-upstream-4.4-testing.git;a=summary
So you can grab the patches from there and apply to your 4.4.0 version,
or just use the latest qemu-upstream-4.4-testing.git tree directly.
Those patches will be part of upcoming Xen 4.4.1 release.
Another option probably is to use qemu-traditional with Xen 4.4.0 .. ?
