Fixed In Version: vdagent-win-0.1-9
Doc Type: Bug Fix
Doc Text:
When connecting to a Windows 7 guest under WAN conditions the vdagent did not restart within the allocated timeout period of 3 seconds. This prevented the guest's mouse from responding to user input. An update has been made to ensure that the vdagent starts correctly to accept new session connections. As a result the guest's mouse will now respond correctly to user input under WAN conditions.

Description Yonit Halperin 2011-10-30 09:33:43 UTC 
Description of problem:
Under WAN conditions (e.g., 1Mbps), I connected spice client to a Windows7 vm, during the VM startup. The mouse didn't work. 
Investigate it with Arnon. Both server and client are in client mouse mode.
However, the agent is killed on the VM and is not restarted.
From the logs we saw, that vdservice attempts to kill the vdagent after a CONNECT event (as it should). It waits 3 seconds for the vdagent to be actually killed, and then it should restart it.
However, it took the agent more than 3 seconds to die, and the vdservice didn't restart it.
It is not totally clear why under WAN it takes longer to kill the agent.
I attached the vdservice and vdagent logs.


Version-Release number of selected component (if applicable):
vdagent-win-0.1-8
virtio-win-1.4.0
spice-client-0.8.2-7
spice-server-0.8.2-4

How reproducible:


Steps to Reproduce:
1.Start a Windows 7 vm
2. Connect to the vm during start up, with Spice client, Under WAN
  
Actual results:
No vdagent is running. i.e., mouse clicks don't work, copy-paste don't work, etc.

Comment 4 Arnon Gilboa 2011-11-22 13:12:05 UTC 
This patch solves agent crash, and it's not risky from other perspectives.
Proposing to rhevm‑3.0.0.
Comment 5 Marian Krcmarik 2011-11-29 15:43:35 UTC 
Switching back to ASSIGNED since the problem still occurs when connecting in early pahse of startup under WAn with low bandwith - ~100 Kbps.

We (Arnon and me) tested some scratch builds to determine the right solution.
