Created attachment 827183 [details] proposed fix could you please confirm that the proposed patch fixes the problem for you?
The patch fixes the problem. Thank you
Retest this issue with virt-manager-0.10.0-8.el7 on NUMA2(ibm-x3850x5-04), currently, the button "Generate from host NUMA configuration" could work well, so, set the status as "VERIFIED"
