[PATCH v3 2/5] remote: Implement virDomainFSFreeze and virDomainFSThaw

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

 



New rules are added in fixup_name in gendispatch.pl to keep the name
FSFreeze and FSThaw. This adds a new ACL permission 'fs_freeze',
which is also applied to VIR_DOMAIN_SNAPSHOT_CREATE_QUIESCE flag.
