I think you grab the <cpu> definition from every host 'virsh capabilities' output, stick it in a file, pass it to cpu-baseline, and it will tell you the most featureful CPU that matches each host. But there isn't any virt-manager support for it. Easier but possibly less featureful way is to just use the oldest CPU model name from the pool of host's capabilities output - Cole _______________________________________________ virt-tools-list mailing list virt-tools-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/virt-tools-list
