Hi Boris,
I've modified your PVH VCPU hotplug support v6 patch series [1] to
support HVM guests running _with_ a device model for XenServer's
purposes. This is useful because it moves the vCPU hotplug handling out
of QEMU and allows it to mostly be shared with PVH. It will also allow
unplugging vCPUs (libxl currently only does cpu-add for upstream qemu).
Are you still planning on continuing with that patch series since your
commit to Linux [2]?

xen/pvh: Enable CPU hotplug
PVH guests don't (yet) receive ACPI hotplug interrupts and therefore
need to monitor xenstore for CPU hotplug event.
