Instead of relying on QEMU to assign PCI addresses and then querying them with 'info pci', manually assign all PCI addresses before starting the guest. These addresses are not stable across reboots. That will come in a later patch NB, the PIIX3 (IDE, FDC, ISA-Bridge) will always have slot 1 and VGA will always have slot 2. We declare the Virtio Balloon gets slot 3, and then all remaining slots are for configured devices. * src/qemu/qemu_conf.c: If -device is supported, then assign all PCI addresses when building the command line * src/qemu/qemu_driver.c: Don't query monitor for PCI addresses if they have already been assigned * tests/qemuxml2argvdata/qemuxml2argv-hostdev-pci-address-device.args, tests/qemuxml2argvdata/qemuxml2argv-net-virtio-device.args, tests/qemuxml2argvdata/qemuxml2argv-sound-device.args, tests/qemuxml2argvdata/qemuxml2argv-watchdog-device.args: Update to include PCI slot/bus information
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
