I have an old Ubuntu KVM (Precise 12.04) host (I know it's old!) and I want to install a guest which runs a newer distro (Xenial 16.04).
When I run
ubuntu-vm-builder it tells me
VMBuilder.exception.VMBuilderUserError: Invalid suite: "xenial". Valid suites are: dapper gutsy hardy intrepid jaunty karmic lucid maverick natty oneiric precise quantal.
Is there a way to 'add' new suites?
