@node Deprecated features | ||
@appendix Deprecated features | ||
|
||
In general features are intended to be supported indefinitely once | ||
introduced into QEMU. 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 -redir (since 2.6.0) | ||
|
||
The ``-redir [tcp|udp]:hostport:[guestaddr]:guestport'' argument is | ||
replaced by either | ||
``-netdev user,id=x,hostfwd=[tcp|udp]:[hostaddr]:hostport-[guestaddr]:guestport'' | ||
(for pluggable NICs, accompanied with ``-device ...,netdev=x'') or | ||
``-nic user,hostfwd=[tcp|udp]:[hostaddr]:hostport-[guestaddr]:guestport'' | ||
(for embedded NICs). The new syntax allows different settings to be | ||
provided per NIC. | ||
|
||
@subsection -smb (since 2.6.0) | ||
|
||
The ``-smb /some/dir'' argument is replaced by either | ||
``-netdev user,id=x,smb=/some/dir '' (for pluggable NICs, accompanied | ||
with ``-device ...,netdev=x''), or ``-nic user,smb=/some/dir'' | ||
(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. |
Oops, something went wrong.
