qemu: add memfd source type Add a new memoryBacking source type "memfd", supported by QEMU (when the capability is available). A memfd is a specialized anonymous memory kind. As such, an anonymous source type could be automatically using a memfd. However, there are some complications when migrating from different memory backends in qemu (mainly due to the internal object naming at this point, but there could be more). For now, it is simpler and safer to simply introduce a new source type "memfd". Eventually, the "anonymous" type could learn to use memfd transparently in a separate change. The main benefits are that it doesn't need to create filesystem files, and it also enforces sealing, providing a bit more safety.

qemu: Use '-machine acpi=on/off' instead of deprecated '-no-acpi' QEMU deprecated the '-no-acpi' option, thus we should switch to the modern way to use '-machine'. Certain ARM machine types don't support ACPI. Given our historically broken design of using '<acpi/>' without attribute to enable ACPI and qemu's default of enabling it without '-no-acpi' such configurations would not work. Now when qemu reports whether given machine type supports ACPI we can do a better decision and un-break those configs. Unfortunately not retroactively.

qemu: Switch to -accel We currently use -machine accel=XXX which is just a syntax sugar for -accel XXX. The former doesn't allow specifying arguments for accelerator, because all arguments passed to -machine are treated as arguments of machine itself. The -accel argument was introduced in QEMU commit v2.9.0-rc0~70^2~19 and since our minimum required version is newer (2.11.0) we can safely assume its existence and use it without any capability.

qemu: Don't use memory-backend-memfd for NVDIMMs If guest is configured to use memfd then the function that build memory-backend-* part of command line will put memory-backend-memfd, always. Even for NVDIMMs. This is not correct, because NVDIMMs need a backing path (usually to a real host NVDIMM device). Therefore, regardless of memfd being requested, we have to stick with memory-backend-file.

qemu_command: Generate memory only after controllers Currently, memory device (def->mems) part of cmd line is generated before any controller. In majority of cases it doesn't matter because neither of memory devices live on a bus that's created by an exposed controller (e.g. there's no DIMM controller, at least not exposed). Except for virtio-mem and virtio-pmem, which do have a PCI address. And if it so happens that the device goes onto non-default bus (pci.0) starting such guest fails, because the controller that creates the desired bus wasn't processed yet. QEMU processes arguments in order. For instance, if virtio-mem has address with bus='0x01' QEMU refuses to start with the following message: Bus 'pci.1' not found Similarly for virtio-pmem. I've successfully tested migration and changing the order does not affect migration stream.
