Commit 49d2e64 (machine: remove qemu_machine_opts global list) made machine machine options specific to machine sub-type, leaving the qemu_machine_opts desc array empty. Sadly this is the place qmp_query_command_line_options is looking for supported options.
As a fix for for 2.3 the machine_qemu_opts are restored only for the scope of qemu-config, bringing together all machines properties. We need to find a better fix for 2.4. Reported-by: Tony Krowiak <[email protected]> Signed-off-by: Marcel Apfelbaum <[email protected]> --- I don't like this approach, but I wouldn't want to loose the 'options per machine type' feature. We'll find something better for 2.4/ util/qemu-config.c | 108 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 108 insertions(+) diff --git a/util/qemu-config.c b/util/qemu-config.c index f3463df..9e8edda 100644 --- a/util/qemu-config.c +++ b/util/qemu-config.c @@ -6,6 +6,7 @@ #include "hw/qdev.h" #include "qapi/error.h" #include "qmp-commands.h" +#include "hw/i386/pc.h" static QemuOptsList *vm_config_groups[32]; static QemuOptsList *drive_config_groups[4]; @@ -148,6 +149,111 @@ static CommandLineParameterInfoList *get_drive_infolist(void) return head; } +/* restore machine options that are now machine's properties */ +static QemuOptsList machine_opts = { + .merge_lists = true, + .head = QTAILQ_HEAD_INITIALIZER(machine_opts.head), + .desc = { + { + .name = "type", + .type = QEMU_OPT_STRING, + .help = "emulated machine" + },{ + .name = "accel", + .type = QEMU_OPT_STRING, + .help = "accelerator list", + },{ + .name = "kernel_irqchip", + .type = QEMU_OPT_BOOL, + .help = "use KVM in-kernel irqchip", + },{ + .name = "kvm_shadow_mem", + .type = QEMU_OPT_SIZE, + .help = "KVM shadow MMU size", + },{ + .name = "kernel", + .type = QEMU_OPT_STRING, + .help = "Linux kernel image file", + },{ + .name = "initrd", + .type = QEMU_OPT_STRING, + .help = "Linux initial ramdisk file", + },{ + .name = "append", + .type = QEMU_OPT_STRING, + .help = "Linux kernel command line", + },{ + .name = "dtb", + .type = QEMU_OPT_STRING, + .help = "Linux kernel device tree file", + },{ + .name = "dumpdtb", + .type = QEMU_OPT_STRING, + .help = "Dump current dtb to a file and quit", + },{ + .name = "phandle_start", + .type = QEMU_OPT_NUMBER, + .help = "The first phandle ID we may generate dynamically", + },{ + .name = "dt_compatible", + .type = QEMU_OPT_STRING, + .help = "Overrides the \"compatible\" property of the dt root node", + },{ + .name = "dump-guest-core", + .type = QEMU_OPT_BOOL, + .help = "Include guest memory in a core dump", + },{ + .name = "mem-merge", + .type = QEMU_OPT_BOOL, + .help = "enable/disable memory merge support", + },{ + .name = "usb", + .type = QEMU_OPT_BOOL, + .help = "Set on/off to enable/disable usb", + },{ + .name = "firmware", + .type = QEMU_OPT_STRING, + .help = "firmware image", + },{ + .name = "kvm-type", + .type = QEMU_OPT_STRING, + .help = "Specifies the KVM virtualization mode (HV, PR)", + },{ + .name = PC_MACHINE_MAX_RAM_BELOW_4G, + .type = QEMU_OPT_SIZE, + .help = "maximum ram below the 4G boundary (32bit boundary)", + },{ + .name = PC_MACHINE_VMPORT, + .type = QEMU_OPT_STRING, + .help = "Enable vmport (pc & q35)", + },{ + .name = "iommu", + .type = QEMU_OPT_BOOL, + .help = "Set on/off to enable/disable Intel IOMMU (VT-d)", + },{ + .name = "secure", + .type = QEMU_OPT_BOOL, + .help = "Set on/off to enable/disable the ARM " + "Security Extensions (TrustZone)", + },{ + .name = "suppress-vmdesc", + .type = QEMU_OPT_BOOL, + .help = "Set on to disable self-describing migration", + },{ + .name = "aes-key-wrap", + .type = QEMU_OPT_BOOL, + .help = "enable/disable AES key wrapping using the " + "CPACF wrapping key", + },{ + .name = "dea-key-wrap", + .type = QEMU_OPT_BOOL, + .help = "enable/disable DEA key wrapping using the " + "CPACF wrapping key", + }, + { /* End of list */ } + } +}; + CommandLineOptionInfoList *qmp_query_command_line_options(bool has_option, const char *option, Error **errp) @@ -162,6 +268,8 @@ CommandLineOptionInfoList *qmp_query_command_line_options(bool has_option, info->option = g_strdup(vm_config_groups[i]->name); if (!strcmp("drive", vm_config_groups[i]->name)) { info->parameters = get_drive_infolist(); + } else if (!strcmp("machine", vm_config_groups[i]->name)) { + info->parameters = query_option_descs(machine_opts.desc); } else { info->parameters = query_option_descs(vm_config_groups[i]->desc); -- 2.1.0
