When we hot-plug a disk device into a qemu guest, we need to retain its PCI address so that it can be removed again later. Currently, we do retain the slot number, but not across libvirtd restarts. Add <state devaddr="xxxx:xx:xx"/> to the disk device XML config when the VIR_DOMAIN_XML_INTERNAL_STATUS flag is used. We still don't parse the domain and bus number, but the format allows us to do that in future. * src/domain_conf.h: replace slotnum with pci_addr struct, add helper for testing whether the address is valid * src/domain_conf.c: handle formatting and parsing the address * src/qemu_driver.c: store the parsed slot number as a full PCI address, and use this address with the pci_del monitor command * src/vbox/vbox_tmpl.c: we're debug printing slotnum here even though it can never be set, just delete it
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.
