So that's easier to review. You are also adding new XML but are completely missing test files which show how it's used and excercise the parser and formatter as well as the qemu driver implementation. The simplest way is to use qemuxmlconftest to add these. You're also referencing 'acpi-generic-initiator' object which is not supported by all versions so you'll need to add a capability flag for it. See qemu_capabilities.c/h
+static int +qemuBuildAcpiInitiatorCommandLine(virCommand *cmd, + const virDomainAcpiInitiatorDef *acpiinitiator) +{ + g_autofree char *obj = NULL; + + obj = g_strdup_printf("acpi-generic-initiator,id=%s,pci-dev=%s,node=%d", + acpiinitiator->name, acpiinitiator->pciDev, acpiinitiator->numaNode); + virCommandAddArgList(cmd, "-object", obj, NULL);
All other code which uses defines -object uses JSON props. You'll have to convert this to use the same approach and use qemuBuildObjectCommandlineFromJSON() to convert the JSON definition to the commandline. Apart from symmetry, this'll provide validation of the generated properties against qemu's internal schemas.
