In the event that a feature needs to be removed, -it will be listed in this appendix. The feature will remain functional -for 2 releases prior to actual removal. Deprecated features may also -generate warnings on the console when QEMU starts up, or if activated -via a monitor command, however, this is not a mandatory requirement. - -Prior to the 2.10.0 release there was no official policy on how -long features would be deprecated prior to their removal, nor -any documented list of which features were deprecated. Thus -any features deprecated prior to 2.10.0 will be treated as if -they were first deprecated in the 2.10.0 release. - -What follows is a list of all features currently marked as -deprecated. - -@section Build options - -@subsection GTK 2.x - -Previously QEMU has supported building against both GTK 2.x -and 3.x series APIs. Support for the GTK 2.x builds will be -discontinued, so maintainers should switch to using GTK 3.x, -which is the default. - -@subsection SDL 1.2 - -Previously QEMU has supported building against both SDL 1.2 -and 2.0 series APIs. Support for the SDL 1.2 builds will be -discontinued, so maintainers should switch to using SDL 2.0, -which is the default. - -@section System emulator command line arguments - -@subsection -no-kvm (since 1.3.0) - -The ``-no-kvm'' argument is now a synonym for setting -``-machine accel=tcg''. - -@subsection -vnc tls (since 2.5.0) - -The ``-vnc tls'' argument is now a synonym for setting -``-object tls-creds-anon,id=tls0'' combined with -``-vnc tls-creds=tls0' - -@subsection -vnc x509 (since 2.5.0) - -The ``-vnc x509=/path/to/certs'' argument is now a -synonym for setting -``-object tls-creds-x509,dir=/path/to/certs,id=tls0,verify-peer=no'' -combined with ``-vnc tls-creds=tls0' - -@subsection -vnc x509verify (since 2.5.0) - -The ``-vnc x509verify=/path/to/certs'' argument is now a -synonym for setting -``-object tls-creds-x509,dir=/path/to/certs,id=tls0,verify-peer=yes'' -combined with ``-vnc tls-creds=tls0' - -@subsection -tftp (since 2.6.0) - -The ``-tftp /some/dir'' argument is replaced by either -``-netdev user,id=x,tftp=/some/dir '' (for pluggable NICs, accompanied -with ``-device ...,netdev=x''), or ``-nic user,tftp=/some/dir'' -(for embedded NICs). The new syntax allows different settings to be -provided per NIC. - -@subsection -bootp (since 2.6.0) - -The ``-bootp /some/file'' argument is replaced by either -``-netdev user,id=x,bootp=/some/file '' (for pluggable NICs, accompanied -with ``-device ...,netdev=x''), or ``-nic user,bootp=/some/file'' -(for embedded NICs).

The new syntax allows different settings to be -provided per NIC. - -@subsection -drive cyls=...,heads=...,secs=...,trans=... (since 2.10.0) - -The drive geometry arguments are replaced by the the geometry arguments -that can be specified with the ``-device'' parameter. - -@subsection -drive serial=... (since 2.10.0) - -The drive serial argument is replaced by the the serial argument -that can be specified with the ``-device'' parameter. - -@subsection -drive addr=... (since 2.10.0) - -The drive addr argument is replaced by the the addr argument -that can be specified with the ``-device'' parameter. - -@subsection -usbdevice (since 2.10.0) - -The ``-usbdevice DEV'' argument is now a synonym for setting -the ``-device usb-DEV'' argument instead. The deprecated syntax -would automatically enable USB support on the machine type. -If using the new syntax, USB support must be explicitly -enabled via the ``-machine usb=on'' argument. - -@subsection -nodefconfig (since 2.11.0) - -The ``-nodefconfig`` argument is a synonym for ``-no-user-config``. - -@subsection -balloon (since 2.12.0) - -The @option{--balloon virtio} argument has been superseded by -@option{--device virtio-balloon}. - -@subsection -machine s390-squash-mcss=on|off (since 2.12.0) - -The ``s390-squash-mcss=on`` property has been obsoleted by allowing the -cssid to be chosen freely. Instead of squashing subchannels into the -default channel subsystem image for guests that do not support multiple -channel subsystems, all devices can be put into the default channel -subsystem image. - -@subsection -fsdev handle (since 2.12.0) - -The ``handle'' fsdev backend does not support symlinks and causes the 9p -filesystem in the guest to fail a fair amount of tests from the PJD POSIX -filesystem test suite. Also it requires the CAP_DAC_READ_SEARCH capability, -which is not the recommended way to run QEMU. This backend should not be -used and it will be removed with no replacement. - -@subsection -no-frame (since 2.12.0) - -The @code{--no-frame} argument works with SDL 1.2 only. The other user -interfaces never implemented this in the first place. So this will be -removed together with SDL 1.2 support. - -@subsection -rtc-td-hack (since 2.12.0) - -The @code{-rtc-td-hack} option has been replaced by -@code{-rtc driftfix=slew}. - -@subsection -localtime (since 2.12.0) - -The @code{-localtime} option has been replaced by @code{-rtc base=localtime}. - -@subsection -startdate (since 2.12.0) - -The @code{-startdate} option has been replaced by @code{-rtc base=@var{date}}. - -@subsection -virtioconsole (since 3.0.0) - -Option @option{-virtioconsole} has been replaced by -@option{-device virtconsole}. - -@subsection -clock (since 3.0.0) - -The @code{-clock} option is ignored since QEMU version 1.7.0. There is no -replacement since it is not needed anymore. - -@subsection -enable-hax (since 3.0.0) - -The @option{-enable-hax} option has been replaced by @option{-accel hax}. -Both options have been introduced in QEMU version 2.9.0. - -@subsection -drive file=json:@{...@{'driver':'file'@}@} (since 3.0) - -The 'file' driver for drives is no longer appropriate for character or host -devices and will only accept regular files (S_IFREG). The correct driver -for these file types is 'host_cdrom' or 'host_device' as appropriate. - -@section QEMU Machine Protocol (QMP) commands - -@subsection block-dirty-bitmap-add "autoload" parameter (since 2.12.0) - -"autoload" parameter is now ignored. All bitmaps are automatically loaded -from qcow2 images. - -@subsection query-cpus (since 2.12.0) - -The ``query-cpus'' command is replaced by the ``query-cpus-fast'' command. - -@subsection query-cpus-fast "arch" output member (since 3.0.0) - -The ``arch'' output member of the ``query-cpus-fast'' command is -replaced by the ``target'' output member. - -@section System emulator devices - -@subsection ivshmem (since 2.6.0) - -The ``ivshmem'' device type is replaced by either the ``ivshmem-plain'' -or ``ivshmem-doorbell`` device types. - -@subsection Page size support < 4k for embedded PowerPC CPUs (since 2.12.0) - -qemu-system-ppcemb will be removed. qemu-system-ppc (or qemu-system-ppc64) -should be used instead. That means that embedded 4xx PowerPC CPUs will not -support page sizes < 4096 any longer. - -@section System emulator machines - -@subsection pc-0.10 and pc-0.11 (since 3.0) - -These machine types are very old and likely can not be used for live migration -from old QEMU versions anymore. A newer machine type should be used instead. - -@section Device options - -@subsection Block device options - -@subsubsection "backing": "" (since 2.12.0) - -In order to prevent QEMU from automatically opening an image's backing -chain, use ``"backing": null'' instead. - -@subsection vio-spapr-device device options - -@subsubsection "irq": "" (since 3.0.0) - -The ``irq'' property is obsoleted. +@include qemu-deprecated.texi @node Supported build platforms @appendix Supported build platforms |
