Y. Srinivasan" , Haiyang Zhang , Hank Janssen , stable List-Id: virtualization@lists.linuxfoundation.org On some loaded windows hosts, we have discovered that the host may not respond to guest requests within the specified time (one second) as evidenced by the guest timing out. Fix this problem by increasing the timeout to 5 seconds. It may be useful to apply this patch to the 3.0 kernel as well. the 3.0 kernel as well. Signed-off-by: K. Y.
