OPTIONS:¶

--help|help|-h

show this help.

--download|download|update

scan the /etc/qemu-web-desktop/machines.conf file for [name.ext] and download them when URL are given. a 'refresh' is then performed. Virtual machine images are stored into /var/lib/qemu-web-desktop/machines. Additional machine descriptions can be given in /etc/qemu-web-desktop/config.d/*.ini files.

--edit|edit [machines|config|web]

edit the VM/machine list, the service configuration file or the service web page. In the case of the VM list, the 'qwdctl download' command is triggered automatically after edit. Set the $EDITOR variable to select the text editor to use. In case the 'qwdctl edit machines' has no effect on the index.html service landing page, specify set 'QWDCTL_INSERT=yes' or option '--machine-insert'. It is recommended to use the '--enable' and '--disable' to manage the VM/machine list.

--gpu|gpu VENDOR:MODEL

configure GPU for pass-through. The GPU_ids are e.g. '10de:1d01'.

--gpu-unlock|gpu-unlock

unlock/re-attach all GPU's to server (uninstall pass-through).

--machines-insert

used with download/refresh, force to modify the index.html service landing page instead of using an include. Same as QWDCTL_INSERT=yes shell variable.

--refresh|refresh

scan the /etc/qemu-web-desktop/machines.conf file, and generate the /var/lib/qemu-web-desktop/machines.html that lists available images to show in the qemu-web-desktop main form. Additional machine descriptions can be given in /etc/qemu-web-desktop/config.d/*.ini files.

--status|status

list running sessions, as well as enabled and disabled machines.

--start|start VM ...

start the given VM or ISO file (full path) in a browser. Connect to it with the displayed URL. Further arguments are passed to the service (see config.pl) e.g. --snapshot_alloc_mem=1 (in GB) and --snapshot_alloc_cpu=2. Changes are lost except when specifying option --snapshot_use_master=1, requiring write access. When running ISO's you may also specify --snapshot_alloc_disk=40 (in GB). Use 'qwdctl --start' to get the full list of default VM settings.

--stop|stop TOKEN

stop sessions matching TOKEN. Some snapshot files may be left-over.

--enable|enable VMNAME|FILE|URL {'DESCRIPTION'}

add or (re)activate a VM name.ext, file or URL. Optional description is given as a string.

--disable|disable VMNAME

deactivate a VM.

--purge|purge {VMNAME}

remove VM files which are inactive and not used. When VM argument is given, only files starting by 'VM' are checked.

--version|version|-v

show qwdctl version.

--yes|-y

assume yes to questions. Same as QWDCTL_YES=1 shell variable.
