After all decisions in (relevant) national championships relevant for CL are now known, here follow the qualified teams for the competition as usual:
Italy: Conegliano (Champion and league round winner), Milano (runner up), Scandicci (third of league round and semi final participant)
Turkey: VakifBank (Champion), Fenerbahce (runner-up) and Eczacibasi (winner of Bronze medal series)
Poland: Rzeszow (Champion), LKS Commercecon Lodz (runner up) and Grot Budowlani Lodz (winner of Bronze medal series)
(Russia: still banned (would be otherwise champion Kaliningrad and runner up Kazan))
Germany: Schwerin (champion) and Dresden (runner up)
France: Paris and Nantes (finalists)
Ukraine: ??? (likely again no participant)
Serbia: Zeleznicar (champion), runner up Ub could be a candidate too
Romania: Alba Blaj (Champion), if eligible and willing (a ban a few years ago, can they afford it?)
Qualification: they can apply as national champions even from leagues lower in ranking. Succession rule of CEV? I don't know (because of Russia and some not willing to take their formal spots it's important).
