Inject VirtIO Windows Driver

Note

This feature is available from vJailbreak v0.1.13 and later.

How to use user-provided virtio-win.iso

Users can upload the virtio-win.iso to the following path on vJailbreak master node:

/home/ubuntu/virtio-win/virtio-win.iso

Note

In vjailbreak VM there is already a folder named virtio-win at /home/ubuntu/. Please make sure to upload to that directory and the name of the file should be virtio-win.iso.

How it works

If the user has scaled up vJailbreak, the ISO is propagated to all the agents. When a Windows VM migration is initiated:

The migration logic checks for /home/ubuntu/virtio-win/virtio-win.iso on the source node.

• If found:
  • The ISO is used for injecting VirtIO drivers into the migrated disk.
  • The ISO is automatically propagated to all agent nodes if needed.
• If not found:
  • vJailbreak attempts to download the ISO from a known upstream source (e.g., fedoraproject.org).
• If both methods fail:
  • Migration fails gracefully with a clear error message.
