[libvirt] virt-install and custom distros

We have an application that builds custom distributions based on RHEL, CentOS or Fedora. We would like to install these over the network using virt-install, but we've run into an issue with the distro check logic. Specifically, virt-install fails unless it finds a string "Red Hat Enterprise Linux", "Fedora" or "CentOS" within the family field of the .treeinfo file. Our application currently sets the family field to the user-provided distro name (see below). We have avoided using the base distro name given trademark concerns. [general] family = <user provided value> variant = <user provided value> We can get virt-install to pass the distro check by setting the family name to one of the accepted values, e.g. [general] family = Fedora variant = [user provided distro name] Is this the expected/desired use for the family and variant fields? Or is there another approach we should consider? Thanks, Kay
