Hmm... -h is common to all targets, ie, you should only find properties that can be passed to -machine for all qemu-system-* binaries (I don't know how s390-squash-mcss landed there but it looks wrong).
The right way to query properties supported by a pseries machine type is: $ ./ppc64-softmmu/qemu-system-ppc64 -machine pseries,help pseries-2.11.kvm-type=string (Specifies the KVM virtualization mode (HV, PR)) pseries-2.11.vsmt=uint32 (Virtual SMT: KVM behaves as if this were the host's SMT mode) pseries-2.11.modern-hotplug-events=bool (Use dedicated hotplug event mechanism in place of standard EPOW events when possible (required for memory hot-unplug support)) pseries-2.11.max-cpu-compat=string (Maximum permitted CPU compatibility mode. Valid values are power6, power7, power7+, power8, power9.) pseries-2.11.resize-hpt=string (Resizing of the Hash Page Table (enabled, disabled, required)) pseries-2.11.kvm-shadow-mem=int (KVM shadow MMU size) pseries-2.11.enforce-config-section=bool (Set on to enforce configuration section migration) pseries-2.11.initrd=string (Linux initial ramdisk file) pseries-2.11.mem-merge=bool (Enable/disable memory merge support) pseries-2.11.firmware=string (Firmware image) pseries-2.11.dtb=string (Linux kernel device tree file) pseries-2.11.suppress-vmdesc=bool (Set on to disable self-describing migration) pseries-2.11.usb=bool (Set on/off to enable/disable usb) pseries-2.11.kernel=string (Linux kernel image file) pseries-2.11.dt-compatible=string (Overrides the "compatible" property of the dt root node) pseries-2.11.igd-passthru=bool (Set on/off to enable/disable igd passthrou) pseries-2.11.dumpdtb=string (Dump current dtb to a file and quit) pseries-2.11.append=string (Linux kernel command line) pseries-2.11.accel=string (Accelerator list) pseries-2.11.kernel-irqchip=OnOffSplit (Configure KVM in-kernel irqchip) pseries-2.11.dump-guest-core=bool (Include guest memory in a core dump) pseries-2.11.phandle-start=int (The first phandle ID we may generate dynamically) pseries-2.11.graphics=bool (Set on/off to enable/disable graphics emulation) -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1721744 Title: Help content missing for newly added machine properties Status in QEMU: New Bug description: Help content missing for newly added machine properties, it would be needed by libvirt and other management layers to query to add support, Thanks. max-cpu-compat,vsmt,modern-hotplug-events,resize-hpt Steps: 1.
