[libvirt-python PATCH] override: add virDomainFSFreeze and virDomainFSThaw API

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

 



Add binding for the new virDomainFSFreeze and virDomainFSThaw functions
added in libvirt 1.2.5. These require override since these take a list
of mountpoints path string. The methods are named 'fSFreeze' and 'fSThaw',
like a existing 'fSTrim' method.
