[pve-devel] [PATCH qemu-server] Fix: cpu hotplug feature can't be changed online

[Alexandre Derumier <aderumier@odiso.com>]

The cpus are passed as devices with specific id only when cpu hotplug is enable
at start.
We can't enable/disable it online or vcpu hotplug api will thrown errors
not finding core id.
