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

afaik you should not directly call libvirt api but use the vdsm api?
but someone with more insight into vdsm can provide better information
than me.

Actually we don't directly call libvirt api, we call it from the wrapped
libvirtconnection like other functions do in vdsm.
