The PCI device addresses are only valid while the VM is running, since they are auto-assigned by QEMU. After shutdown they must all be cleared. Future QEMU driver enhancement will allow for persistent PCI address assignment * src/conf/domain_conf.h, src/conf/domain_conf.c, src/libvirt_private.syms Add virDomainDefClearPCIAddresses() method for wiping out auto assigned PCI addresses * src/qemu/qemu_driver.c: Clear PCI addresses at VM shutdown
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.
