Comment 5 for bug 1442310

I dig into code more and got several questions:

1) seems the logic of horizon is get volumes and instances then use local loop
if we offer an option to search, e.g filter instances by each volume ,should this increase the
REST API request and db hit? maye performance is not that good?

2) Also, seems the attach detach info is recorded at cinder db ,should it be better to
submit this to cinder instead of nova ?

both apply to 2nd question on floating IP, thanks
