Hello, I want to add the info of VCPU mapping into the XML, because we cannot manage VCPU mapping automatically when a domain starts or reboots. But in the following patch, the function written in "TODO" which I wanted has not been accepted. https://www.redhat.com/archives/libvir-list/2006-August/msg00015.html If I provided the patch managing VCPU mapping in the XML, do you accept it? Regards, Yuzuru Asano.
