Discuss unique advantages and issues with the paravirtual filesystems I would like to discuss and get community feedback and ideas on how can we avoid cache duplication(data and metadata) between host and guests.? Given that both server (host) and client (guest) is running on the same hardware we should be able to avoid double caching of both(host and guest) filesystems. For details about VirtFS, please see my OLS paper http://www.sciweavers.org/publications/virtfs-virtualization-aware-file-system-pass-through Thanks Venkateswararao Jujjuri (JV) VirtFS - KVM LTC, IBM. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
