Trying to load qemu img snapshots using "SKIPTO=…" on openQA client command fails to load the snapshot even though the according hard disk image has the according snapshot.

I added a debug output to find the error message and will provide a PR to os-autoinst for that, but that's not the issue here.

steps to reproduce

  • clone any USBinstall job from o3/osd
  • make sure to run your worker with --no-cleanup and such for using qemu snapshots
  • after one run, clone again with SKIPTO=…
  • observe the error in autoinst-log.txt


H1. qemu is confused where to load snapshots from when specifying a simulated USB thumbdrive as second drive which is not a cdrom


Need to run the complete test from scratch without the use of snapshots.

but rollback works in these scenarios, no? I assume the problem is that we pass usbstick as SLE-12-SP3-Server-DVD-x86_64-Build0207-Media1.iso,snapshot=on - but of course the snapshot didn't happen there. But I can't predict what happens without the snapshot=on - the code is as old as snapshoting in os-autoinst :)

  • Tags set to beginner, os-autoinst, snapshots
  • Target version changed from Ready to future

I think this could be a good beginner task. Considering that and because the impact is low we can remove it from the backlog of the SUSE QA Tools team.
