tests/libqos: x86_64/pc machine node
Add pc machine for the x86_64 QEMU binary. This machine contains an i440FX-pcihost driver, that contains itself a pci-bus-pc that produces the pci-bus interface. Signed-off-by: Emanuele Giuseppe Esposito <e.emanuelegiuseppe@gmail.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
