Description

In poo#21838 the need for multimachine tests on PowerVM was mentioned.
To cite coolo on what needs to be done:

I don't think there is inherit problem - but you would need to undo a lot of qemu specific hardcoding. But you can create vlans for the lpars and then have PARALLEL_WITH 2 lpars.

AC1: Multimachine tests can run on PowerVM
   AC1.1: Implement vland handling for LPARs
   AC1.2: Find all qemu hardcodings and adapt the backend to do MM tests on other backends

Suggestion

Configure vlans between the lpars and treat them as machines in the network with a proper worker class (see coolo's comment)

I claim we don't do anything about it - and handle powervm lpars just like phyiscal machines in our network. They are there and if they can be used for MM tests is defined by worker class. If the admins setup a proper vlan or not is up to the tests writers.

I see this only happening after #37372 and even then I doubt that qsf-u has the capacity to work on this within the early milestones of M21 so a bit later

If I understood QA-CSS correctly they plan similar work and want to have it but do not yet have a ticket or similar so not that important or urgent. Therefore delaying.

@szarate I missed that you assigned this ticket to "[tools]" as you kept slindomansilla as assignee. IMHO the comment from #33697#note-4 is still valid and there are no plans by the QA tools team to do more implementation about this. However considering that our powerVM backends can be treated just the same as bare metal IMHO we have a solution already: Tests can be triggered in parallel with no problem and synchronization primitives can be used. As the network can not be fully virtual of course then the network admin needs to ensure according separation where needed. What we can do is maybe mention this explicitly in documentation.

Trying to clarify in documentation what can be done / needs to be done: https://github.com/os-autoinst/openQA/pull/3256
It's not that much though but I consider it's what we can do, the rest is for test maintainers to show what's possible and tell the network admin what's missing :)
