This page is about features that have been removed from QEMU (after a deprecation period), and what new features should be used instead.
Removed command line parameters
| Parameter | Deprecated in | Removed in | Replacement |
|---|---|---|---|
| -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 -drive trans=t -drive secs=s -drive heads=h -drive cyls=c -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| -net channel | v2.6.0 | v2.12.0 | Option has been replaced by -net user,guestfwd=...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| -net dump | v2.10.0 | v2.12.0 | -net dump[,vlan=n][,file=filename][,len=maxlen] has been replaced by -object filter-dump,id=id,netdev=dev[,file=filename][,maxlen=maxlen].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. |
| -redir | v2.6.0 | v3.1.0 | 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. |
| -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. |
Removed HMP commands
| Parameter | Deprecated in | Removed in | Replacement |
|---|---|---|---|
| usb_add and usb_remove | v2.10.0 | v2.12.0 | Replaced by device_add and device_del (use device_add help for a list of available devices) |
| host_net_add and host_net_remove | v2.10.0 | v2.12.0 | Replaced by netdev_add and netdev_del |
Removed devices
| Device | Deprecated in | Removed in | Replacement |
|---|---|---|---|
| ivshmem | v2.6.0 | v4.0.0 | Replaced by either the ivshmem-plain or ivshmem-doorbell |
| spapr-pci-vfio-host-bridge | v2.6.0 | v2.12.0 | The spapr-pci-vfio-host-bridge device type has been replaced by the spapr-pci-host-bridge device type. |
