`bwlimit`: `[clone=<LIMIT>] [,default=<LIMIT>] [,migration=<LIMIT>] [,move=<LIMIT>] [,restore=<LIMIT>]` ::

Set bandwidth/io limits various operations.

`clone`=`<LIMIT>` ;;

bandwidth limit in MiB/s for cloning disks

`default`=`<LIMIT>` ;;

default bandwidth limit in MiB/s

`migration`=`<LIMIT>` ;;

bandwidth limit in MiB/s for migrating guests

`move`=`<LIMIT>` ;;

bandwidth limit in MiB/s for moving disks

`restore`=`<LIMIT>` ;;

bandwidth limit in MiB/s for restoring guests from backups

`console`: `<applet | html5 | vv | xtermjs>` ::

Select the default Console viewer. You can either use the builtin java applet (VNC; deprecated and maps to html5), an external virt-viewer comtatible application (SPICE), an HTML5 based vnc viewer (noVNC), or an HTML5 based console client (xtermjs). If the selected viewer is not available (e.g. SPICE not activated for the VM), the fallback is noVNC.

`email_from`: `<string>` ::

Specify email address to send notification from (default is root@$hostname)

`fencing`: `<both | hardware | watchdog>` ('default =' `watchdog`)::

Set the fencing mode of the HA cluster. Hardware mode needs a valid configuration of fence devices in /etc/pve/ha/fence.cfg. With both all two modes are used.

WARNING: 'hardware' and 'both' are EXPERIMENTAL & WIP

`http_proxy`: `http://.*` ::

Specify external http proxy which is used for downloads (example: 'http://username:password@host:port/')

`mac_prefix`: `(?^i:[a-f0-9]{2}(?::[a-f0-9]{2}){0,2}:?)` ::

Prefix for autogenerated MAC addresses.

`max_workers`: `<integer> (1 - N)` ::

Defines how many workers (per node) are maximal started  on actions like 'stopall VMs' or task from the ha-manager.

`migration`: `[type=]<secure|insecure> [,network=<CIDR>]` ::

For cluster wide migration settings.

`network`=`<CIDR>` ;;

CIDR of the (sub) network that is used for migration.

`type`=`<insecure | secure>` ('default =' `secure`);;

Migration traffic is encrypted using an SSH tunnel by default. On secure, completely private networks this can be disabled to increase performance.

`migration_unsecure`: `<boolean>` ::

Migration is secure using SSH tunnel by default. For secure private networks you can disable it to speed up migration. Deprecated, use the 'migration' property instead!
