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
