Re: [libvirt] [PATCH v3 17/24] conf: Add XML for individual vCPU hotplug

Individual vCPU hotplug requires us to track the state of any vCPU. To allow this add the following XML: <domain> ... <vcpu current='2'>3</vcpu> <vcpus> <vcpu id='0' enabled='yes' hotpluggable='no' order='1'/> <vcpu id='1' enabled='yes' hotpluggable='yes' order='2'/> <vcpu id='1' enabled='no' hotpluggable='yes'/> </vcpus> ... The 'enabled' attribute allows to control the state of the vcpu. 'hotpluggable' controls whether given vcpu can be hotplugged and 'order' allows to specify the order to add the vcpus. --- Notes: v3: - fixed extraction of the hotpluggable state v2: - added documentation - added tweak of hotplug state when reconnecting to a VM - discussed design requests in previous thread docs/formatdomain.html.in | 40 ++++++ docs/schemas/domaincommon.rng | 25 ++++ src/conf/domain_conf.c | 154 ++++++++++++++++++++- src/conf/domain_conf.h | 6 + src/qemu/qemu_domain.c | 11 +- .../generic-vcpus-individual.xml | 23 +++ tests/genericxml2xmltest.c | 2 + tests/testutils.c | 4 +- 8 files changed, 261 insertions(+), 4 deletions(-) create mode 100644 tests/genericxml2xmlindata/generic-vcpus-individual.xml
