Hostname service in qemu may fail due to namespace issues. It happens
only when qemu subprocess run with `shell=False` (default).
```
systemctl status systemd-hostnamed.service
...
Failed to set up mount namespacing: /run/systemd/unit-root/dev:
Read-only file system
Failed at step NAMESPACE spawning /lib/systemd/systemd-hostnamed:
Read-only file system
Main process exited, code=exited, status=226/NAMESPACE
...
```
The issue was caught in a downstream, not Isar image itself.

These SSH keys are generated with empty passphrase and supposed
to be used for non-interactive SSH access to qemu machines
testsuite runs.

This creates `ci` user on a target and configures it for
non-interactive access to the image via SSH.
Non-interactive access is provided by placing testsuite's public part
of ssh key to `authorized_keys`.
This allows non-interactive SSH access to the machine with executing
custom commands on the guest VM.
Also, NetworkManager is installed to the image to make ethernet on
target auto configured and thus port forwarding from host to qemu
machine would work.

In order not to spoil `isar-image-base` or `local.conf.sample`,
put CI-specific configuration to a separate image recipe.
This includes SSH configuration for separate `ci` user that is done
in `isar-ci-ssh-setup` recipe.

This removes hardcoded `isar-image-base` image name used in
`testsuite/start_vm.py`.
Now, user can pass custom value with `-i` or `--image` option
(e.g. `isar-image-debug` or any other value used in their downstream.

By specifying `cmd='<command>'` it's now possible to run VM and
execute the command over SSH connection.
If this is not specified, tests uses previous approach, with
parsing output log and searching some specific fragments.

By specifying `script='<file.sh>'` it's now possible to run VM and
execute local script over SSH connection.

+## Manual running
+
+There is a tool `start_vm.py` which is the replacement for the bash script in
+`isar/scripts` directory. It can be used to run image previously built:
+
+```
+./start_vm.py -a amd64 -b /build -d bullseye -i isar-image-base
+```
+
+# Tests for running commands under qemu images
+
+Package `isar-image-ci` configures `ci` user with non-interactive SSH access
+to the machine. Image `isar-image-ci` preinstalls this package.
+
+Example of test that runs qemu image and executes remote command under it:
+
+```
+ def test_getty_target(self):
+ self.init()
+ self.vm_start('amd64','bookworm', \
+ image='isar-image-ci',
+ cmd='systemctl is-active getty.target')
+```
+
+To run something more complex than simple command, custom test script
+can be executed instead of command:
+
+```
+ def test_getty_target(self):
+ self.init()
+ self.vm_start('amd64','bookworm', \
+ image='isar-image-ci',
+ script='test_getty_target.sh')
+```
+
+The default location of custom scripts is `isar/testsuite/`. It can be changed
+by passing `-p test_script_dir="custom_path"` to `avocado run`
+arguments.
