VDI copy/init/provision ops in xapi are all buffered. Means I/O completes only deferred. The agent should carefully sync back buffers to disk and test file status, or gust corruption goes unnoticed.
Presently covers: * XVA import * Raw VDI import * VDI.copy * VM.provision (e.g. the Debian Etch post-installation script) There might be more, which I've been missing then. Some of the changes below just use O_SYNC on the output fd. Most assume a prior xen-api-libs patch to make Unixext.fsync provide the necessary error detail.
