* src/qemu/qemu_command.c (qemuBuildChrChardevStr): Alter the
chardev alias.
(qemuBuildCommandLine): Output an id for the chardev counterpart.
* tests/qemuxml2argvdata/*: Update tests to match.
Reported by Daniel P. Berrange.
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
The current character device syntax uses either
-serial tty,path=/dev/ttyS2
Or
-chardev tty,id=serial0,path=/dev/ttyS2 -serial chardev:serial0
With the new -device support, we now prefer
-chardev file,id=serial0,path=/tmp/serial.log -device isa-serial,chardev=serial0
This patch changes the existing -chardev syntax to use this new
scheme, and fallbacks to the old plain -serial syntax for old
QEMU.
The monitor device changes to
-chardev socket,id=monitor,path=/tmp/test-monitor,server,nowait -mon chardev=monitor
In addition, this patch adds --nodefaults, which kills off the
default serial, parallel, vga and nic devices. THis avoids the
need for us to explicitly turn each off
Change -monitor, -serial and -parallel output to use -chardev if it is
available.
* src/qemu/qemu_conf.c: Update qemudBuildCommandLine to use -chardev where
available.
* tests/qemuxml2argvtest.c tests/qemuxml2argvdata/: Add -chardev equivalents
for all current serial and parallel tests.
