[PATCH 2/8] virDriverFeatureIsGlobal: Handle VIR_DRV_FEATURE_REMOTE

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



VIR_DRV_FEATURE_REMOTE is a special flag which is asserted only when the
connection is remote. All drivers implementing it must return 0 for it
to work. Handle it in the global handler and add a comment why.
