Hello Wei,I'm sorry for neglecting this email-thread for so long, I was active only on GH. Let me answer some of your questions in line.

Upload to the host machine? Great, for testing that's the best start. You can use any similar `Ubuntu` release and add the s390 variant.I have found a way to upload images, and upload our Ubuntu images.
once you add the `machine` types I mentioned in PR, you should be using `--vt-machine-type s390` to check images of your architecture.[root@zs95kv2 images]# /avocado/avocado/scripts/avocado list --vt-type qemu --vt-list-guests
Basically you need to add the s390 variant in `avocado-vt/shared/cfg/guest-os/Linux/Ubuntu/14.04.3-server.*.cfg`. For start check the differences getween the available i386 and x86_64 and try to adjust it to s390. Most of the entries are related to `unattended_install` test, but for start I'd avoid trying to set everything right. Important is to make `boot` test work, then you can start exploring what is needed for `unattended_install` (usually vmlinuz location and some kernel options)..... Linux.Ubuntu.14.04.3-server.i386.i440fx (missing ubuntu-14.04.3-server-32.qcow2) *Linux.Ubuntu.14.04.3-server.x86_64.i440fx* Linux.Debian.6.0.7.x86_64.i440fx (missing debian-6-0-7-64.qcow2) .... But how to enable it on our s390x platform?
Don't forget to re-run `avocado vt-bootstrap` after each change in `guest-os` to propagate the changes to your system. (I'd recommend `avocado vt-bootstrap --vt-guest-os RHEL.7.devel --vt-no-downloads` to speedup the process. It does not matter which guest-os you run afterwards, but choosing a distro which does not have asset file associated speedups the bootstrap significantly.
Yes, JeOS is currently only built for x86_64 and you can simply ignore it. To run on other architectures you need to always use `--vt-guest-os` or you can change the default in `/etc/avocado/...` config file.Best regards, - Li， Wei （李 伟） zKVM Solution Test IBM China Systems & Technology Lab, Beijing E-Mail: [email protected] Tel: 86-10-82450631 Notes: Wei WA Li/China/IBM Address: 3BW298, Ring Bldg.

I read some source and I think I should add some guest information for JeOS.23?
Honestly I never remember this. So what I usually do is I run `avocado run unattended_install.cdrom.extra_cdrom_ks.default_install.aio_threads --vt-guest-os ...`. It fails and gives you the file it was looking for. Then I use `wget ... -O ...` to put the image into the correct location with the right name.But I think JeOS.23 is not supported by our platform, so should I uplado an supported ubuntu to this server? Where it should be located, I can't find any information about how to upload new images. (except http://avocado-vt.readthedocs.io/en/latest/WritingTests/DefiningNewGuests.html?highlight=guest) And how to add our environment info to ubuntu cfg to make it be supported?

There are global defaults for Centos in CentOS.cfg, then version-specifics in `7.0.cfg` and per-arch specifics in `$machine_type.cfg`.
You might check the product in `~/avocado/data/avocado-vt/backends/qemu/cfg/guest-os.cfg`, which is the file used (when `qemu` provider is used) for guest-os definition. Keep in mind it's re-created on `vt-bootstrap` execution, so all changes should be made in `shared/cfg/guest-os`.

OK so the arch name should most probably be `s390x` to match the uname.
This is the `machine_type`. I'd suggest something like `s390-virtio` for now, which is quite similar to `arm64-mmio` version which is being used. It's not necessary to map the `machine_type` to the actual machine-type in qemu, though.[root@zs95kv2 avocado]# qemu-kvm -M \?

OK, hopefully it makes some things clearer, best regards, Lukáš
