The current QEMU code allocates PCI addresses incrementally starting at 4. This is not satisfactory because the user may have given some addresses in their XML config, which need to be skipped over when allocating addresses to remaining devices. It is thus neccessary to maintain a list of already allocated PCI addresses and then only allocate ones that remain unused. This is also required for domain device hotplug to work properly later. * src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Add APIs for creating list of existing PCI addresses, and allocating new addresses. Refactor address assignment to use this code * src/qemu/qemu_driver.c: Pull PCI address assignment up into the qemuStartVMDaemon() method, as a prelude to moving it into the 'define' method. Update list of allocated addresses when connecting to a running VM at daemon startup. * tests/qemuxml2argvtest.c, tests/qemuargv2xmltest.c, tests/qemuxml2xmltest.c: Remove USB product test since all passthrough is done based on address * tests/qemuxml2argvdata/qemuxml2argv-hostdev-usb-product.args, tests/qemuxml2argvdata/qemuxml2argv-hostdev-usb-product.xml: Kil unused data files
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.
