Update: Probably what causing this related to bug: https://bugzilla.redhat.com/show_bug.cgi?id=1138335 Don't think there's anything intelligent to do here - if guest1 corrupts the disk guest2 has nothing to do. Moving to the virt stakeholders in case I missed something, but from a storage perspective there's no AI here. there's no AI in virt either, though we really try!:-) The only thing coming to my mind is to have a general warning when you are marking disk as shared and rw that (obviously) you have to manually take care of concurrency. Allon, thoughts? A nice RFE?:-) We could have something like that ("note that this disk is writable by VM1 and VM2"), but I wonder if it's worth the effort.
will close if no one picks it up in few months... (which is likely) Closing old bugs. If this issue is still relevant/important in current version, please re-open the bug. |
