[libvirt] guest-fsfreeze-freeze: Does it allow for any guest-fsfreeze_hook in Windows guest machine.

Hi, When guest agent command "guest-fsfreeze-freeze" is invoked on a linux VM, a hook is provided to do execute any pre-script before actually doing a freeze. int64_t qmp_guest_fsfreeze_freeze(Error **errp) { ::: execute_fsfreeze_hook(FSFREEZE_HOOK_FREEZE, &local_err); ::: } Can the same thing be done in case of Windows guest machine? I could not find similar thing in case of Windows ("qga_vss_fsfreeze()->requester_freeze()") where I can put a script (a hook) to do some preprocessing. Regards, ~Puneet
