Clean up header guards that don't match their file name Header guard symbols should match their file name to make guard collisions less likely. Offenders found with scripts/clean-header-guards.pl -vn. Cleaned up with scripts/clean-header-guards.pl, followed by some renaming of new guard symbols picked by the script to better ones.

qemu-config: parse configuration files to a QDict Change the parser to put the values into a QDict and pass them to a callback. qemu_config_parse's QemuOpts creation is itself turned into a callback function. This is useful for -readconfig to support keyval-based options; getting a QDict from the parser removes a roundtrip from QDict to QemuOpts and then back to QDict. Unfortunately there is a disadvantage in that semantic errors will point to the last line of the group, because the entries of the QDict do not have a location attached.

qemu-config: load modules when instantiating option groups Right now the SPICE module is special cased to be loaded when processing of the -spice command line option. However, the spice option group can also be brought in via -readconfig, in which case the module is not loaded. Add a generic hook to load modules that provide a QemuOpts group, and use it for the "spice" and "iscsi" groups.

void qemu_add_drive_opts(QemuOptsList *list);
qdev: add command line option to set global defaults for properties. This patch adds infrastructure and command line option for setting global defaults for device properties, i.e. you can for example use -global virtio-blk-pci.vectors=0 to turn off msi by default for all virtio block devices. The config file syntax is: [global] driver = "virtio-blk-pci" property = "vectors" value = "0" This can also be used to set properties for devices which are not created via -device but implicitly via machine init, i.e. -global isa-fdc,driveA=<name> This patch uses the mechanism which configures properties for the compatibility machine types (pc-0.10 & friends). The command line takes precedence over the machine type values. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

qemu-config: qemu_read_config_file() reads the normal config file Introduce a new function qemu_read_config_file which reads the VM configuration from a config file.

qemu-option: Add qemu_config_parse_qdict() This function basically parses command-line options given as a QDict replacing a config file. For instance, the QDict {"section.opt1": 42, "section.opt2": 23} corresponds to the config file: [section] opt1 = 42 opt2 = 23 It is possible to specify multiple sections and also multiple sections of the same type. On the command line, this looks like the following: inject-error.0.event=reftable_load,\ inject-error.1.event=l2_load,\ set-state.event=l1_update This would correspond to the following config file: [inject-error "inject-error.0"] event = reftable_load [inject-error "inject-error.1"] event = l2_load [set-state] event = l1_update Signed-off-by: Max Reitz <mreitz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
