[Libguestfs] [PATCH 0/3] resolve conflict between manual and libvirt-assigned PCI addresses

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2034160 The first patch extends our current <qemu:commandline> hack, moving the virtio-net-pci device to slot 0x1E, where it is very unlikely to conflict with any libvirt-assigned PCI address. The second patch is only refactoring. The third patch resolves the conflict on libvirt >= 3.8.0 in a better way (suggested by Rich): such libvirt versions permit SLIRP network address and prefix specifications right in the <interface> element. Therefore we can have libvirt manage the virtio-net device for us, similarly to virtio-rng, virtio-scsi, and virtio-serial. The (updated) <qemu:commandline> hack is preserved for libvirt < 3.8.0. Gruesomely meticulously tested. (See the Notes sections on the patches.) Sanity-tested both back-ends *without* the "--network" switch as well. Thanks, Laszlo Laszlo Ersek (3): launch-libvirt: place our virtio-net-pci device in slot 0x1e lib: extract NETWORK_ADDRESS and NETWORK_PREFIX as macros launch-libvirt: add virtio-net via the standard <interface> element lib/guestfs-internal.h | 18 ++++++++++++++++++ lib/launch-direct.c | 2 +- lib/launch-libvirt.c | 34 ++++++++++++++++++++++++++++++---- 3 files changed, 49 insertions(+), 5 deletions(-) base-commit: 4af6d68e2d8b856d91fa5527216ea3db04556086 -- 2.19.1.3.g30247aa5d201
