Description

Decide on cache mode and 'discard'.

History

#1 Updated by rpalethorpe over 4 years ago

  • Status changed from Workable to In Progress

Hardcoded cache.no-flush=on because we do not care about data integrity after a host crash as the tests need to run to completion anyway.

#2 Updated by rpalethorpe over 4 years ago

  • Status changed from In Progress to Resolved

no-flush saves a significant amount of time. Discard may be useful for reducing VM image sizes, but it is probably better left for another PR.
