 System emulator command line arguments
 --------------------------------------
 
-``-net ...,name=``\ *name* (removed in 5.1)
-'''''''''''''''''''''''''''''''''''''''''''
+``-hdachs`` (removed in 2.12)
+'''''''''''''''''''''''''''''
+
+The geometry defined by ``-hdachs c,h,s,t`` should now be specified via
+``-device ide-hd,drive=dr,cyls=c,heads=h,secs=s,bios-chs-trans=t``
+(together with ``-drive if=none,id=dr,...``).
+
+``-net channel`` (removed in 2.12)
+''''''''''''''''''''''''''''''''''
+
+This option has been replaced by ``-net user,guestfwd=...``.
+
+``-net dump`` (removed in 2.12)
+'''''''''''''''''''''''''''''''
+
+``-net dump[,vlan=n][,file=filename][,len=maxlen]`` has been replaced by
+``-object filter-dump,id=id,netdev=dev[,file=filename][,maxlen=maxlen]``.
+Note that the new syntax works with netdev IDs instead of the old "vlan" hubs.
+
+``-no-kvm-pit`` (removed in 2.12)
+'''''''''''''''''''''''''''''''''
+
+This was just a dummy option that has been ignored, since the in-kernel PIT
+cannot be disabled separately from the irqchip anymore. A similar effect
+(which also disables the KVM IOAPIC) can be obtained with
+``-M kernel_irqchip=split``.
+
+``-tdf`` (removed in 2.12)
+''''''''''''''''''''''''''
+
+There is no replacement, the ``-tdf`` option has just been ignored since the
+behaviour that could be changed by this option in qemu-kvm is now the default
+when using the KVM PIT. It still can be requested explicitly using
+``-global kvm-pit.lost_tick_policy=delay``.
+
+``-drive secs=s``, ``-drive heads=h`` & ``-drive cyls=c`` (removed in 3.0)
+''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
+
+The drive geometry should now be specified via
+``-device ...,drive=dr,cyls=c,heads=h,secs=s`` (together with
+``-drive if=none,id=dr,...``).
+
+``-drive serial=``, ``-drive trans=`` & ``-drive addr=`` (removed in 3.0)
+'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
+
+Use ``-device ...,drive=dr,serial=r,bios-chs-trans=t,addr=a`` instead
+(together with ``-drive if=none,id=dr,...``).
+
+``-net ...,vlan=x`` (removed in 3.0)
+''''''''''''''''''''''''''''''''''''
+
+The term "vlan" was very confusing for most users in this context (it's about
+specifying a hub ID, not about IEEE 802.1Q or something similar), so this
+has been removed. To connect one NIC frontend with a network backend, either
+use ``-nic ...`` (e.g. for on-board NICs) or use ``-netdev ...,id=n`` together
+with ``-device ...,netdev=n`` (for full control over pluggable NICs). To
+connect multiple NICs or network backends via a hub device (which is what
+vlan did), use ``-nic hubport,hubid=x,...`` or
+``-netdev hubport,id=n,hubid=x,...`` (with ``-device ...,netdev=n``) instead.
+
+``-no-kvm-irqchip`` (removed in 3.0)
+''''''''''''''''''''''''''''''''''''
+
+Use ``-machine kernel_irqchip=off`` instead.
+
+``-no-kvm-pit-reinjection`` (removed in 3.0)
+''''''''''''''''''''''''''''''''''''''''''''
+
+Use ``-global kvm-pit.lost_tick_policy=discard`` instead.
+
+``-balloon`` (removed in 3.1)
+'''''''''''''''''''''''''''''
+
+The ``-balloon virtio`` option has been replaced by ``-device virtio-balloon``.
+The ``-balloon none`` option was a no-op and has no replacement.
+
+``-bootp`` (removed in 3.1)
+'''''''''''''''''''''''''''
+
+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 on-board NICs).
+The new syntax allows different settings to be provided per NIC.
+
+``-redir`` (removed in 3.1)
+'''''''''''''''''''''''''''
+
+The ``-redir [tcp|udp]:hostport:[guestaddr]:guestport`` option is replaced
+by either ``-netdev
+user,id=x,hostfwd=[tcp|udp]:[hostaddr]:hostport-[guestaddr]:guestport``
+(for pluggable NICs, accompanied with ``-device ...,netdev=x``) or by the option
+``-nic user,hostfwd=[tcp|udp]:[hostaddr]:hostport-[guestaddr]:guestport``
+(for on-board NICs). The new syntax allows different settings to be provided
+per NIC.
+
+``-smb`` (removed in 3.1)
+'''''''''''''''''''''''''
+
+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 on-board NICs).
+The new syntax allows different settings to be provided per NIC.
+
+``-tftp`` (removed in 3.1)
+''''''''''''''''''''''''''
+
+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.
+
+``-localtime`` (removed in 3.1)
+'''''''''''''''''''''''''''''''
+
+Replaced by ``-rtc base=localtime``.
+
+``-nodefconfig`` (removed in 3.1)
+'''''''''''''''''''''''''''''''''
+
+Use ``-no-user-config`` instead.
+
+``-rtc-td-hack`` (removed in 3.1)
+'''''''''''''''''''''''''''''''''
+
+Use ``-rtc driftfix=slew`` instead.
+
+``-startdate`` (removed in 3.1)

+``-vnc ...,tls=...``, ``-vnc ...,x509=...`` & ``-vnc ...,x509verify=...``
+'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''

+The "tls-creds" option should be used instead to point to a "tls-creds-x509"
+object created using "-object".
+
+``-net ...,name=...`` (removed in 5.1)
+''''''''''''''''''''''''''''''''''''''
 
 The ``name`` parameter of the ``-net`` option was a synonym
 for the ``id`` parameter, which should now be used instead.
