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: capabilities: Replace aliased machine type by copy of the canonical machine The previous approac of just purging the alias combined with the fact that we filled in fake machine types in the test data meant that if a test case used an alias machine type such as 'pc' or 'q35' it would not properly resolve to the actual data returned by qemu. This started to be a problem since the CPU driver now looks at the default CPU reported with the machine type. This patch replaces the original approach of just removing the alias by replacing it with a copy of the machine type data which the type would alias to. This means that we are using the real data while we don't modify the test output after every qemu upgrade. Additionally this change will allow us to drop adding the fake machine types later. The test fallout is from actually excercising the CPU driver with actual data. Signed-off-by: Peter Krempa <pkrempa@redhat.com> Reviewed-by: Michal Privoznik <mprivozn@redhat.com>

qemu: capabilities: Re-enable JSON syntax for -device Now that qemu fixed device unplug when JSON syntax is used with -device we can re-enable the feature. Since the old capability string representation is condemned by suggesting filtering it as a workaround we must introduce a new string. To achieve this the original capability position is renamed to X_QEMU_CAPS_DEVICE_JSON_BROKEN_HOTPLUG and a new position with the original name QEMU_CAPS_DEVICE_JSON is introduced to prevent us having to change the rest of the code.

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.
