Configures the VNC display for a virtual machine (VM).
| vm | Designates a virtual machine. |
| vm_name | Specifies the VM name to configure the VNC display for. |
| vnc | Specifies providing a display number for VNC access. |
| none | Disables VNC access (default). |
| vnc_display | Specifies the VNC screen number. Range is 0–15. |
By default, VNC access is disabled.
For the VNC display number (or screen number), you can use the values from 0 to 15. These correspond to TCP ports 5,900 to 5,915.
Multiple VMs can be configured with the same VNC display, but VMs configured with the same display number cannot run at the same time. A VM cannot be started if the VNC port is already in use.
For security reasons, the VNC display is only accessible using SSH tunnel.
The following example enables VNC on VM "vm1" with display number 3:
# configure vm vm1 vnc 3
