Image Cataloguing Exchange
Tony - mail I sent last workday on 15th & Owen's mail, recapping : Image metadata had been uploaded to file catalog images from Ian G and Predrag instantiated and contextualised with identical scripts by both Andrea and Thomas. Ian's image needed hard coded mac address removing.
Problems instantiated images signed with UK and ? (sound bad here) certificates
Owen has a fix believed to be definitive
Owen - found one more problem today - also now fixed
Tony - seem now to have contextualisation worked out - standard set of scripts will work for images generated by different people. Needs fuller documentation.
Andrea - in a good state, a bit more documentation to ease process for adding ssh key and what else the script can do etc.
Thomas - perhaps we can provide some defaults - eth0, dhcp etc. We had probs with DHCP as we wanted a static config, but will get rid of this.
Tony - Michel and Steve Thorne managed instantiation of previously cataloged StratusLab image but uinable to instantiate their own images. Has anyone done work with StratusLab? (Ian - RAL planning to but will not be immediate due to resources)
Owen - one issue is batch queue facilities for managing VM resources. How does user select VM environment. Nice if we could standardise this across the world.
Tony - WLCG just set up technology evaluation working group. Virtualisation is on their list to look at. Jeff Templon and Marcus (? - sound again...) Imagine they are looking at how virtualisation fits into the grid.
Cern VMIC
Belimiro - CERN and ASGC will collaborate for a VMIC implementation to replace what we are using and of course will support all HEPiX specifications.
The implementation will address what is specified in the document already distributed in the HEPiX WG.
Owen - found bug in upgrades to image list. Will need DB schema upgrade to fix
AOB
Tony - WLCG meeting who will be there? Ian C, Romain, Owen, Thomas
Are there things we should discuss more than how we have got on with StratusLab?
Owen - need to focus on getting things documented. Would like feedback on what they want how they would like things improved
Tony - so those two - docs and stratuslab
Tony - can we repeat successful work days? Doodle poll for weeks in July, August September
Owen - email poll on topics not yet addressed
Actions
Tony - actions - doodle poll for work days - email poll for unaddressed topics - discuss with Marcus/Jeff integration with batch systems/grid environments
Owen asked about selecting VMs in torque maui. Tony/Ian - suggested this is somewhat mixed/linked with Marcus/Jeff's work in the technology evaluation working group.
