Description

Motivation

The current implementation of the spvm backend makes use of functions ( e.g. use_ssh_serial_console located in lib/ipmi_backend_utils.pm) from other "backends".
This is good enough for a first proof of concept but for the sake of clarity and further maintainability this should reside in a separate file which is shared/included from the backends using it.

Acceptance criteria

  • AC1: Have clearly seperated backends with shared common functions
  • AC2: Do not include any functions from other backends (e.g. from ipmi into spvm)

Suggestions

  • Extract method "use_ssh_serial_console" into a common lib, e.g. "ssh_remote_console_backend_something_foobar"
  • Call git grep 'BACKEND.*pvm' and only work on these occurences, that excludes e.g. boot_from_pxe.pm
  • Find occurences like in https://github.com/os-autoinst/os-autoinst-distri-opensuse/blob/master/lib/susedistribution.pm#L554 where we look for "s390x || ipmi || spvm" and replace this with an explicit function returning a boolean value for what it really is, e.g. "no_local_tty" or "remote_backend" or "relies_on_ssh_terminal"
  • Create followup sibling ticket for all necessary work for other backends

Further details

Focus on spvm, leave the rest for the parent epic. "Having a single verification run is enough" says okurz

Example for a change:

- if (check_var('BACKEND', 'foo') || check_var('BACKEND', 'bar')) {
+ sub backend_is_remote { return check_var('BACKEND', 'foo') || check_var('BACKEND', 'bar') }
+ if (backend_is_remote) {
