Custom images and SSH keys · Virtual machines

Save keys once, upload your own disk images, and turn a VM into a template.

SSH keys

Open Settings → SSH keys, give the key a name and paste the contents of your .pub file (for example ssh-ed25519 AAAA…). The key is then offered when you create a VM. You can also add a key inline in the create form.

ssh-keygen -t ed25519 -C "my-laptop" cat ~/.ssh/id_ed25519.pub

Upload a disk image

Open Settings → Custom images, pick the project, then choose a file and upload it. The image appears under Custom images when you create a VM in that project.

Save a VM as an image

Under Save a VM as an image, pick a stopped VM and name the image. Its disk is cloned into a reusable template. Stop the VM first if it is running.
