Signed-off-by: Boris Ostrovsky --- I am not sure this is really needed since it's no different from how we do hotplug for PV or HVM/qemu-trad guests. I may have been a bit too grandiose by describing yesterday's patch as "add CPU hotplug support". It was really enabling existing functionality. docs/misc/hvmlite.markdown | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/docs/misc/hvmlite.markdown b/docs/misc/hvmlite.markdown index c1b75c6..1a2e866 100644 --- a/docs/misc/hvmlite.markdown +++ b/docs/misc/hvmlite.markdown @@ -80,3 +80,8 @@ are used in order to bring up secondary vCPUs: * `VCPUOP_down` is used to bring down a vCPU. * `VCPUOP_is_up` is used to scan the number of available vCPUs. + +## VCPU hotplug ## + +VCPUs can be hot-plugged or hot-removed by writing "online" or "offline" to +xenstore's /local/domain//cpu//availability entry -- 2.1.0
