This is because the 'qemu' binar is the 32-bit emulator. To make x86_64 guests work, you need to install the qemu-system-x86_64 binary, or a KVM binary called 'kvm' or 'qemu-kvm'. Once those are installed, you should see another <guest> appear in that capabilities XML daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :| -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
