Hello Wei,

as I mentioned previously, the `list` command does not accept 
`--vt-arch` nor `--vt-machine-type` and automatically applies `x86_64`, 
`i440fx` filters. You could temporarily change the defaults in the 
avocado-vt plugin, or you can simply wait as we are working on the 
support for changing the machine for other commands. I'd suggest simply 
replacing the `x86_64` with `s390`, or just omitting the unnecessary 
parts as when you use `--machine-type` in `avocado run` it adds the 
`s390-virtio` filter.

Actually cartesian_config (avocado-vt variants/params generator) is 
quite simple. It knows nothing about architectures, machine types, guest 
hw, nor tests. It simply takes all variants and applies global filters 
like "only s390x", which means it ignores all other variants (like 
`x86_64` or `ppc64le`).

For Fedora I'm using `--vt-guest-os Fedora.23` so if you already defined 
`Ubuntu..s390` the `--vt-guest-os Ubuntu.14.04.3-server` should be 
executable and along with `--vt-machine-type s390-virtio --vt-arch 
s390x` should give you just a single variant. If you haven't defined the 
`Ubuntu..s390` yet, you can do it similarly as I defined the 
`Fedora.23.s390`.

Currently you can't, because `s390x` is omitted due to default `avocado 
list` filters (`only s86_64`). But when you use `avocado run` it'll be 
used if you define the `--vt-machine-type`.

Hopefully this works for you. We neglected other archs for a while, but 
you can see the `avocado list` is on our TODO list 
https://trello.com/c/aumjDJde/715-add-vt-list-machines-and-vt-list-archs 
(most probably won't be implemented in this release, but should be 
implemented in the next one, which means in less than 4 weeks - no 
guarantee, though).

Lukáš
