The "acpi" configuration file section matches command-line option "acpitable".Three options are using different names on the command line and in configuration file.The "irq" property of the "spapr-vscsi", "spapr-vlan" and "spapr-vty" devices is deprecated with no replacement.Ĭonsult the "Deprecated Features" appendix for the full list of historically deprecated features/options.The "file" driver for drives is no longer appropriate for character or host devices and will only accept regular files (S_IFREG).The "arch" memeber in the reply to query-cpus-fast is deprecated, use "target" instead.The "pc-0.10" and "pc-0.11" machines are now deprecated.The non-functional "-clock" option will be removed soon.Option "-virtioconsole" is deprecated, use "-device virtconsole" instead.The "arch" output member of the "query-cpus-fast" command is deprecated.Some 32-bit guests on the "virt" machine may need "-machine highmem=off" if they are unable to support LPAE and are confused by the PCI ECAM now being above the 4GB mark in the address space.The deprecated xlnx-ep108 machine was removed.The default for VFIO's "display" option has been changed from "auto" to "off", because "auto" requires an OpenGL-compatible configuration for vGPUs that require GL support.PPC support for explicitly allocated RMAs has been removed (kernel support removed in 2015).The qemu-img "convert -s snapshot_id_or_name" argument has been removed.The "xlnx-ep108" machine has been replaced by the "xlnx-zcu102" machine.Use "-drive if=none" and pass the options to "-device" instead. The deprecated -drive options "geometry", "addr" and "serial" have been removed.Use "-netdev" with IDs or the "hubport" netdev instead. The "vlan" parameter of the "-net" option has been removed.Use "-machine kernel_irqchip=off" instead. Option "-no-kvm-irqchip" has been removed.Use "-global kvm-pit.lost_tick_policy=discard" instead. Option "-no-kvm-pit-reinjection" has been removed.They will continue to work in this release (though configure will warn you about the unsupported status), but in a future QEMU release we may drop support for those hosts unless somebody volunteers to help us with maintaining them (and can provide build/CI machines). Unsupported host setups are CPU and operating systems which we do not have access to and are thus unable to test. 2.2 New deprecated options and features.
