This patch converts NUMA configurations between the Xen libxl configuration file format and libvirt's XML format. ... Xen xl.cfg domain configuration:
vnuma = [["pnode=0","size=2048","vcpus=0-1","vdistances=10,21,31,21"], ["pnode=1","size=2048","vcpus=2-3","vdistances=21,10,21,31"], ["pnode=2","size=2048","vcpus=4-5","vdistances=31,21,10,21"], ["pnode=3","size=2048","vcpus=6-7","vdistances=21,31,21,10"]]
If there is no XML <distances> description amongst the <cell> data the conversion schema from xml to native will generate 10 for local and 20 for all remote instances.
Does xl have the same behavior? E.g. with
Yes.
vnuma = [["pnode=0","size=2048","vcpus=0-1"], ["pnode=1","size=2048","vcpus=2-3"], ["pnode=2","size=2048","vcpus=4-5"], ["pnode=3","size=2048","vcpus=6-7"]]
will distances be 10 for local and 20 for remote nodes?
Yes.
