The feature is already merged in oVirt 3.5.0 alpha 1. Currently, it only ha= s the virtual numa node (vNode) pin to host numa node(pNode) information wh= ich is configured by user. We plan to collect the runtime information from = vdsm that vNode run in which pNodes. Since this information is dynamic and = changes more often, we want to let this information reported in the process= of vm stats report. According to the above requirement, we will do the following development in= both engine and vdsm: Vdsm side: 1. In vm module, we will add a function to collect and calculate the = real-time information that vNode run in pNodes. From caps module, we can ge= t the cpu mapping information of each pNode; from vm conf, we can get the v= cpu mapping information of each vNode; from libvirt api, we can get each vc= pu run in which physical cpu runtime. According to the information, we can = calculate the vNode run in pNodes information runtime. 2. Add a key in vm stat map to hold the information and report it to = engine. Engine side: 1. Currently we have the structure to store the vNode run in pNode in= formation. In the structure, we have a field "ispinned" to represent if the= vNode is configured by user to pin to the pNode, or it is runtime run in t= he pNode. Now we only need to parse the reported information from vdsm and = update it in db. We will open a bug to implement the requirement and merge it into 3.5.0. Any comments and suggestions are welcome.
