This patch teaches testutil how to read multi-line input files with
backspace-newline line continuation markers.
The patch also breaks up all the single-line arguments test input files into
multi-line files with lines shorter than 80 characters.
Skip IB700 when assigning PCI slots.
Note: the I6300ESB watchdog _is_ a PCI device.
To test this: I applied this patch to libvirt-0.8.3-2.fc14 (rebasing
it slightly: qemu_command.c didn't exist in that version) and
installed this on my machine, then tested that I could successfully
add an ib700 watchdog device to a guest, start the guest, and the
ib700 was available to the guest. I also added an i6300esb (PCI)
watchdog to another guest, and verified that libvirt assigned a PCI
device to it, that the guest could be started, and that i6300esb was
present in the guest.
Note that if you previously had a domain with a ib700 watchdog, it
would have had an <address type='pci' .../> clause added to it in the
libvirt configuration. This patch does not attempt to remove this.
You cannot start such a domain -- qemu gives an error if you try.
With this patch you are able to remove the bogus address element
without libvirt adding it back.

To try and ensure that people upgrading from old QEMU get guests
with the same PCI device ordering, change the way we assign addrs
to match QEMU's default order. This should make Windows less
annoyed.
* src/qemu/qemu_conf.c: Follow QEMU's default PCI ordering
logic when assigning addresses
* tests/*.args: Update for changed PCI addresses
We already use the '-nodefaults' command line arg with QEMU to stop
it adding any default devices to guests. Unfortunately, QEMU will
load global config files from /etc/qemu that may also add default
devices. These aren't blocked by '-nodefaults', so we need to also
add the '-nodefconfig' arg to prevent that.
Unfortunately these global config files are also used to define
custom CPU models. So in blocking global hardware device addition
we also block definitions of new CPU models. Libvirt doesn't know
about these custom CPU models though, so it would never make use
of them anyway. Thus blocking them via -nodefconfig isn't a show
stopping problem. We would need to expand libvirt's own CPU model
XML database to support these instead.
* src/qemu/qemu_conf.c: Add '-nodefconfig' if available
* tests/qemuxml2argvdata/: Add '-nodefconfig' to all data files which
have '-nodefaults' present
Replace
-balloon virtio
With
-device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x3
This allows it to get correct assigned PCI address as declared in
previous patch
* src/qemu/qemu_conf.c: Convert Virtio ballon to -device and
give it an explicit PCI address
* tests/qemuxml2argvdata/qemuxml2argv-*args: Add in virtio balloon
where appropriate
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
