[Bug 1466486] [NEW] Various usability issues with adt-buildvm-ubuntu-cloud

Public bug reported:

$ adt-buildvm-ubuntu-cloud -r wily

Similar to bug 1460066, it would be nice if I discovered this before
downloading the image, or the downloaded image were cached so I didn't
have to download it again.

Second, on retry I get:

Could not access KVM kernel module: Permission denied
failed to initialize KVM: Permission denied
qemu failed with status 1

...because I didn't belong to the kvm group.

My workflow often involves running autopkgtest on a fresh VM, so I hit
these kinds of things often. Maybe a image download cache is the only
real solution that will work, rather than trying to manage each thing
individually?
