The patch series based on discussion in RFC [1].

I wonder if we'd better add some property like "transient logs" instead
of adding a flag to destoy API.

Yes libguestfs uses virDomainDestroyFlags to terminate a VM and it is
intended client of this new flag but it or other clients may want to use
shutdown API or use autodestroy domains with same log behaviour. Then
for the current task we only need to support this property in domain xml
I guess.
