When performing online backups, applications are not aware of guest-agent freeze/thaw commands and therefore the filesystem may be in an inconsistent state due to pending disk flushes.
For Linux, there's support for guest-agent hooks on freeze/thaw (Bug 911569), which can be used to notify applications (or stop/start daemons). On Windows, the correct way to handle freeze/thaw is using the VSS API.
Some details about VSS:

Update: Hitachi is proposing it upstream. Please review the patch and help them get it merged:
I don't think there's a need fro any libvirt integration. However, I'll keep an eye on this, if something pops up.
I don't see any room for libvirt involvement here as I've stated in comment 2. Since then the nature of the bug hasn't changed so I am closing this one. If somebody disagrees please do reopen.
