File vdsm/virt/snapshot.py:

Line 52: self._log.info("Freezing guest filesystems")
Line 53:
Line 54: try:
Line 55: frozen = self._dom.fsFreeze()
It took me a while to realize, and now I have to ask.
Libvirt here is just passing the buck to the GA, which, in the case of qemu-ga, will do the dirty work using ioctl(FIFREEZE) inside the VM.

Ditto for fsThaw below
Line 56: except libvirt.libvirtError as e:
Line 57: self._log.warning("Unable to freeze guest filesystems: %s", e)
Line 58: code = e.get_error_code()
Line 59: if code == libvirt.VIR_ERR_AGENT_UNRESPONSIVE:
