Furthermore, if your domain is already running, then you can hotplug the tuning via the virDomainGetSchedulerParametersFlags() and virDomainSetSchedulerParametersFlags() API, with parameter names such as VIR_DOMAIN_SCEDULER_VCPU_PERIOD which maps back to the<period> sub-element of the<cputune> domain XML. These APIs are already exposed via the 'virsh schedinfo' command.
Hi Eric,
Those APIs are really the one I needed, thanks very much for the help. After a rough test, it works!
though, I can't find the VIR_DOMAIN_SCEDULER_VCPU_PERIOD macro in the libvirt source code...
It's in include/libvirt/libvirt.h.in, which gets installed as <libvirt.h> for application use. -- Eric Blake eblake@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
