Hi All,

I have filed the following bug for CPU hot-add issue:

Bug 979260 - cpu hot-add doesn't work with upstream libvirt 1.0.6 + qemu
1.5.50

The hotplug feature in qemu 1.5 uses a new monitor command. The support was recently added to libvirt by:

commit c12b2be5169298708cf727ed9ccd42e9d89a9737

    qemu: Implement new QMP command for cpu hotplug

    This patch implements support for the "cpu-add" QMP command that plugs
    CPUs into a live guest. The "cpu-add" command was introduced in QEMU
    1.5. For the hotplug to work machine type "pc-i440fx-1.5" is required.

The commit will be included in the upcomming 1.1.0 release of libvirt.

Peter
