## Suggestions
* Investigate how zypper fails because of packagekit retaining the lock, see https://openqa.opensuse.org/tests/2407873/#step/unlock_luks2_vol_tpm2/10 should not be relevant as the problem is very likely just that we load a snapshot
* Confirm if the missing tpm socket is relevant for the specific failure '/tmp/mytpm14/swtpm-sock': No such file or directory; maybe the socket was closed here since this is a snapshot which loads a new qemu instance
* Check if the warning message does not already show up in maybe even passed jobs
* Apparently not (e.g. https://openqa.opensuse.org/tests/2404868)
* Try to reproduce the problem, e.g. with os-autoinst t/99-full-stack.t when adding corresponding SWTPM variables and loading qemu snapshots
* Ensure that such message about swtpm is only shown if there is a relevant, related error
* Confirm the fix in the related ticket #112241
