Comment 5 for bug 1765668

This sounds like an issue to do with general Ubuntu enablement on this hardware.

uvtool is just a wrapper around libvirt, cloud-init and Ubuntu cloud images. I don't consider a problem booting some specific hardware, architecture or configuration to be a bug in uvtool unless it is shown to actually be a problem in uvtool itself.

Please start by using libvirt and/or cloud-init against the cloud images directly. If this works, please describe what you're doing so we can understand what uvtool does differently. If it doesn't work, then the problem can't be considered to be in uvtool.
