Hi all,
I'm working on the NUMA feature of oVirt.
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.
Thanks & Best Regards
