2. WLCG Collaboration workshop follow-up
Tony reported on last weeks WLCG Collaboration workshop.
Tony noted that there are still users who are unclear about why it is important that root access not be allowed in VMs. Concerns were voiced again about possible performance loss.
There was further discussion of the possible use of CernVM-FS for distributing experiment software to physical as well as virtual WNs. (And the possible benefit of using the same mechanism for both.)
We need to continue making our case for endorsed VM images.
3. VMIC Plan
Owen and Romain have held some discussions. They would like to work face to face next Tony to 'formally¹ invite Owen to visit CERN to work on this further.
4. ImageTesting Results
Sebastien has successfully instantiated, and inspected, images generated by Andrea. Testing process for Andreas images is documented.
Need further images to test Mohamed at LAL will provide some and provided a means to transmit them so will Owen. Further work still needed on conextualisation.
There was a brief discussion of genuine use cases where images cannot be mounted and what the implications would be for forensics.
5. Actions
Tony to write to Desy inviting Owen to CERN. Owen and Mohamed to provide further images for Sebsatien to test.
There are minutes attached to this event.
