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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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

    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: 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 support for VCPU unplug
  RFC: qemu: hotplug: Add DEVICE_(ADDED|DELETED) events for vcpus
