52 The freeze or thaw functionality of application is important to guarantee
53 the application consistent backup.
55 But for VM guest running on Hyper-V, the corresponding VSS is
59 But it is not aware of the freeze/thaw notification from Hyper-V host.
62 is designed to notify application freeze/thaw request.
63 Thus, it plays a role of broker to forward the freeze/thaw command from Hyper-V host
64 to userland application if it registered VSS service on
66 VM, and sends the result back to Hyper-V host.
72 When Hyper-V host wants to take a snapshot of the
79 received the request and forward the request to userland application if it is
83 received the VSS_SUCCESS response from application, the
88 will inform Hyper-V host that VSS is not supported.
89 In addition, there is a default timeout limit before sending response to Hyper-V host.
90 If the total response time from application and
93 will occur and VSS unsupported is responded to Hyper-V host.
95 After Hyper-V host confirmed the

100 After application finished freezing, it should inform
104 After all freezing on both application and
108 will inform Hyper-V host that freezing is done.
112 If there is any error occurs or timeout happened, the freezing is failed on Hyper-V side.
114 Hyper-V host will send thaw request after taking the snapshot, typically, this period is
115 very short in order not to block the running application.

121 There is also a timeout check before sending response to Hyper-V host.
123 All the default timeout limit used in VSS capability check, freeze or thaw is the same.
129 If application does not register VSS,
134 an error (-1) will be returned, and errno was set.
