[Avocado-devel] How to create a s390-virtio image.

[Lukáš Doktor]

Hello Wei,

this is an issue quite high on our todo list. The `avocado list` does 
not support `--vt-arch`, nor `--vt-machine-type` and simply assumes the 
default (x86_64). Anyway the `run` command does support 
`--vt-machine-type s390-virtio --vt-arch 390x`.

My workflow to install the F23 guest on RHEL7 host is (non-optimized):

```bash
# Install qemu
git clone https://github.com/qemu/qemu.git --recursive
cd qemu
yum install zlib-devel glib2-devel -y
CXFLAGS="-lrt" CFLAGS="-lrt" QEMU_CFLAGS="-lrt" ./configure 
--target-list="s390x-softmmu" --enable-kvm
make -j 3
make install

# Install avocado
git clone https://github.com/avocado-framework/avocado.git
git clone https://github.com/avocado-framework/avocado-vt.git

curl "https://bootstrap.pypa.io/get-pip.py" -o "get-pip.py"
python get-pip.py

cd avocado
yum install python-devel libvirt-python libvirt -y
make requirements
cd ../avocado-vt
make requirements
cd -
make install
cd -
make install
yum install tcpdump -y
avocado vt-bootstrap --vt-guest-os Fedora.23

# Playing with it
# Try running boot (should fail as there is no image)
avocado run --vt-guest-os Fedora.23 --vt-arch s390x --vt-machine-type 
s390-virtio --vt-qemu-bin /usr/local/bin/qemu-system-s390x boot
# Install it
yum install genisoimage
mkdir  /usr/share/avocado/data/avocado-vt/isos/linux
wget 
https://dl.fedoraproject.org/pub/fedora-secondary/releases/23/Server/s390x/iso/Fedora-Server-DVD-s390x-23.iso 
-O 
/usr/share/avocado/data/avocado-vt/isos/linux/Fedora-Server-DVD-s390x-23.iso
modprobe kvm
avocado run --vt-guest-os Fedora.23 --vt-arch s390x --vt-machine-type 
s390-virtio --vt-qemu-bin /usr/local/bin/qemu-system-s390x 
unattended_install.cdrom.extra_cdrom_ks.default_install.aio_threads 
--show-job-log
# And now we can run it (or any other test)
avocado run --vt-guest-os Fedora.23 --vt-arch s390x --vt-machine-type 
s390-virtio --vt-qemu-bin /usr/local/bin/qemu-system-s390x boot
```

I'm sorry for confusion, we plan to add the `arch/machine` to the `list` 
commands too.

Kind regards,
Lukáš
