[PATCH 08/14] nwfilter: pass vm name in when instantiating filters

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

 



The vm name is not needed for any functional requirement, but it will be
useful when debugging problems to identify which VM is associated with a
filter, since UUID is not human friendly.
