@hixiaobo have you tested with 4.18.0.0 ? as far as I know, both are supported.

I have checked the doc（http://docs.cloudstack.apache.org/en/latest/adminguide/storage.html?highlight=migration#id2） KVM does not support Migrating Storage For a Running VM，though t's supported on XenServer and VMware.

@hixiaobo the doc is probably not update-to-date. I think all are supported now. (1) local <-> local (2) local <-> share; (3) cross-cluster migration please refer to https://github.com/apache/cloudstack/pull/2983

AFAIK @weizhouapache is correct, both features are supported already. Is there any reason to keep this open @hixiaobo?
