Since I'm a procrastinator and I wanted to do this after full node-name support
is added I'm kind of late for this release here. Since oVirt is asking for this
feature for a very long time I would like to deliver it ASAP though.
This series adds a event which is fired once a guest writes beyond a configured
offset in the backing file. The threshold offset is configurable via a new API.
This series is in RFC state since I did not manage to polish few details mostly
connected to node names:
- currently only the top level image can be selected
- some blockjobs may clear the remembered node names and thus break this
( re-detection of the backing chain needs to be connected with node name
detection )
- the node name detection code is VERY crude
- I'm not sure how well it plays with qcow images, since I select only the top
level node (qcow protocol) rather than the file backing it
- the documentation probably sucks since I did not proof-read
Any feedback is welcome.
