Virtual Media

Mount Drive

LeafKVM can mount the following image formats:

ISO
other formats in development

Only one virtual drive may be active at a time, and the USB mode must be chosen before mounting.

The internal storage space available for storing images is approximately 12 GiB.

Mounting Methods

Storage Mount

Storage Mount uses image files that have been uploaded into LeafKVM’s internal storage.

Delivers maximum throughput (near USB 2.0 peak speed)
Most reliable for long installs and reboots
Requires uploading the image beforehand

For the best overall experience, Storage Mount is recommended.

URL Mount

URL Mount streams an image directly from a public HTTP/HTTPS link.

How it behaves:

LeafKVM fetches each data block on demand as the target machine reads it
Predictive caching improves responsiveness by preloading expected blocks
The UI displays live block read and bandwidth metrics

You may select from built-in popular URLs or supply your own.
This method is useful when the image is already hosted online and you prefer not to upload it.

Browser Mount

Browser Mount streams the image through WebRTC, using your browser as the data source.

Process overview:

LeafKVM forwards block-read requests to your browser
The browser reads the local file and streams the data back in real time
The tab must remain open because your browser acts as the virtual drive backend
Predictive pre-caching helps reduce latency for sequential reads

This option is ideal when you want to mount an image instantly without uploading
and without hosting it on the internet.

USB Classes

LeafKVM can emulate a virtual optical drive.

Installers that expect CD/DVD media
Firmware with stronger compatibility for optical devices
ISO-based utilities and legacy systems

Mass Storage class is required.
