Revision as of 13:36, 18 February 2019
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 |
|---|---|---|---|
| -balloon | v2.12.0 | v3.1.0 | The -balloon option has been replaced by -device virtio-balloon.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 serial=r -drive trans=t -drive secs=s -drive heads=h -drive cyls=c -drive 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| -net channel | v2.6.0 | v2.12.0 | Option has been replaced by -net user,guestfwd=… |
| -net dump | v2.10.0 | v2.12.0 | -net dump[,vlan=n][,file=filename][,len=maxlen] has been replaced by -object filter-dump,id=id,netdev=dev[,file=filename][,maxlen=maxlen].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. |
| -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 -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. |
| -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 …,tls=… -vnc …,x509=… -vnc …,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" |
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. |
Removed machine types
| Machine | Deprecated in | Removed in | Replacement |
|---|---|---|---|
| dummy (m68k) | v2.9.0 | v2.9.0 | Use the none machine with the loader device instead. |
| pc-0.10 - pc-0.11 | v3.0.0 | v4.0.0 | Use a newer pc-i440fx-x.y machine type instead. |
| s390-virtio | v2.6.0 | v2.6.0 | Use the s390-ccw-virtio machine instead. |
| xlnx-ep108 | v2.11.0 | v3.0.0 | The EP108 was an early access development board that is no longer used. Use the xlnx-zcu102 machine instead. |
