This page is about features that have been removed from QEMU (after a [https://qemu.weilnetz.de/doc/qemu-doc.html#Deprecated-features deprecation period]), and what new features should be used instead.
The information about removed features has been integrated into the main QEMU documentation now. Please see this page for more details:

|-
| -balloon
| v2.12.0
| v3.1.0
| The '''-balloon''' option has been replaced by '''-device virtio-balloon'''.
|-
| -bootp
| v2.6.0
| v3.1.0
| 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.
|-
| -drive&nbsp;serial=r<br>-drive&nbsp;trans=t<br>-drive&nbsp;secs=s<br>-drive&nbsp;heads=h<br>-drive&nbsp;cyls=c<br>-drive&nbsp;addr=a
| v2.10.0
| v3.0.0
| The drive geometry should now be specified via '''-device …,drive=dr,cyls=c,heads=h,secs=s,bios-chs-trans=t,addr=a,serial=r''' (together with '''-drive if=none,id=dr,…''').
|-
| -hdachs
| v2.10.0
| v2.12.0
| 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,…''').
|-
| -localtime
| v2.12.0
| v3.1.0
| Replaced by '''-rtc base=localtime'''
|-
| -net channel
| v2.6.0
| v2.12.0
| Option has been replaced by '''-net user,guestfwd=…'''
|-
| -net dump
| v2.10.0
| v2.12.0
| '''<nowiki>-net dump[,vlan=n][,file=filename][,len=maxlen]</nowiki>''' has been replaced by '''<nowiki>-object filter-dump,id=id,netdev=dev[,file=filename][,maxlen=maxlen]</nowiki>'''. Note that the new syntax works with netdev IDs instead of the old "vlan" hubs.
|-
| -net …,vlan=x
| v2.9.0
| v3.0.0
| 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,…''' (together with '''-device …,netdev=n''') instead.
|-
| -nodefconfig
| v2.11.0
| v3.1.0
| Use '''-no-user-config''' instead.
|-
| -no-kvm-irqchip
| v1.3.0
| v3.0.0
| Use '''-machine kernel_irqchip=off''' instead.
|-
| -no-kvm-pit
| v1.3.0
| v2.12.0
| There is no replacement, since this was just a dummy option that has been ignored.
|-
| -no-kvm-pit-reinjection
| v1.3.0
| v3.0.0
| Use '''-global kvm-pit.lost_tick_policy=discard''' instead.
|-
| -redir
| v2.6.0
| v3.1.0
| The '''<nowiki>-redir [tcp|udp]:hostport:[guestaddr]:guestport</nowiki>''' argument is replaced by either '''<nowiki>-netdev user,id=x,hostfwd=[tcp|udp]:[hostaddr]:hostport-[guestaddr]:guestport</nowiki>''' (for pluggable NICs, accompanied with '''-device …,netdev=x''') or '''<nowiki>-nic user,hostfwd=[tcp|udp]:[hostaddr]:hostport-[guestaddr]:guestport</nowiki>''' (for embedded NICs). The new syntax allows different settings to be provided per NIC.
|-
| -rtc-td-hack
| v2.12.0
| v3.1.0
| Use '''-rtc driftfix=slew''' instead.
|-
| -smb
| v2.6.0
| v3.1.0
| 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.
|-
| -startdate
| v2.12.0
| v3.1.0
| Replaced by '''-rtc base=date'''.
|-
| -tdf
| v1.3.0
| v2.12.0
| 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=discard'''.
|-
| -tftp
| v2.6.0
| v3.1.0
| 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.
|-
| -vnc&nbsp;…,tls=…<br/>-vnc&nbsp;…,x509=…<br/>-vnc&nbsp;…,x509verify=…
| v2.5.0
| v3.1.0
| The "tls-creds" option should be used instead to point to a "tls-creds-x509" object created using "-object"
