We use swift as Secondary Storage with XenServer, did not test with KVM. So you need a staging NFS share that is used by the SSVM->hypervisor, staging NFS is used to temporary store template while creating a new Instance from a template.
SSVM VM communicate to Swift via the MGT interface and probably via the storage interface if configured (I haven't test that). in the case of XenServer, the Hypervisor interact directly with Swift to send volume snapshot directly to swift instead of interacting with the SSVM. Swift as secondary storage can only be used with the API V1 with tempauth. There is some features that does not work well, as you need to turn off differential disk snapshot in Global Settings, and the download percentage indicator is not working when importing ISO or Template from URL. also the extract template download link is not working, but template can be download from Swift directly. I would suggest to do a lot of tests to make sure it work as your requirements.
