[libvirt] [PATCH 00/27] qemu: add support for modern vcpu hotplug and unplug

This adds support for vcpu hotplug and unplug using device_add and device_del. Patches 1 and 2 are already mostly acked. Peter Krempa (27): qemu: monitor: Return structures from qemuMonitorGetCPUInfo qemu: monitor: Return struct from qemuMonitor(Text|Json)QueryCPUs qemu: caps: Add capability for query-hotpluggable-cpus command qemu: Forbid config when topology based cpu count doesn't match the config qemu: capabilities: Extract availability of new cpu hotplug for machine types qemu: monitor: Extract QOM path from query-cpus reply qemu: monitor: Add support for calling query-hotpluggable-cpus qemu: monitor: Add algorithm for combining query-(hotpluggable-)-cpus data tests: Add test infrastructure for qemuMonitorGetCPUInfo tests: cpu-hotplug: Add data for ppc64 platform including hotplug tests: cpu-hotplug: Add data for ppc64 out-of-order hotplug tests: cpu-hotplug: Add data for ppc64 without threads enabled qemu: domain: Extract cpu-hotplug related data qemu: domain: Prepare for VCPUs vanishing while libvirt is not running qemu: setcpus: Report better errors qemu: setcpus: Move NUMA setup code into the block checking live def qemu: setvcpus: Extract setting of maximum vcpu count util: Extract and rename qemuDomainDelCgroupForThread to virCgroupDelThread conf: Add XML for individual vCPU hotplug qemu: migration: Prepare for non-contiguous vcpu configurations qemu: command: Add helper to convert vcpu definition to JSON props qemu: process: Copy final vcpu order information into the vcpu definition qemu: command: Add support for sparse vcpu topologies qemu: Use mondern vcpu hotplug approach if possible qemu: hotplug: Allow marking unplugged devices by alias qemu: hotplug: Add
