My idea now is to work with Paolo at understanding how the same qemu
'transaction' and 'drive-reopen' commands can do both snapshot mirroring
and streaming mirroring, then I hope to have a counter-proposal RFC
posted by Monday, with an implementation sometime next week, that
exposes streaming mirroring via virDomainBlockRebase.
... of course this doesn't extend to rounds 1-3, which are a fine
feature and match what will be in QEMU 1.1.
An initial sketch of the mirror/stream API is at
