| 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: |

| |
| | -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 serial=r<br>-drive trans=t<br>-drive secs=s<br>-drive heads=h<br>-drive cyls=c<br>-drive addr=a
| |
| | v2.10.0
| |
| | v3.0
| |
| | 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,...''').
| |
| |-
| |
| | -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| | Option has been replaced by '''-net user,guestfwd=...'''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''' has been replaced by '''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.
| |
| |-
| |
| | -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.
| |
| |-
| |
| | -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.
| |
| |-
| |
| | -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=slew'''.
| |
| |-
| |
| | -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.
