[Qemu-devel] [RFC V3 0/7] Giving names to BlockDriverState graph nodes

["Benoît Canet" <benoit@irqsave.net>]

This partial series start to add some node-name manipulation from QMP.
In particular it allow to take snapshots of quorum files.
I post it in a partial state to spread the reviewing load.

Best regards

Benoît
