Bug 804933

Hi all,

   I have tested it on qemu-kvm-0.12.1.2-2.253.el6.x86_64 with the seabios-0.6.1.2-15.el6.x86_64, but the result of my test still hit this issue, the RTC wake up does not work for windows 7 guest. I have no idea about how to configure windows to wakeup with RTC, maybe miss some steps, please help to check my steps.

Version-Release number of selected component (if applicable):
host info:
# uname -r && rpm -q qemu-kvm
2.6.32-251.el6.x86_64
qemu-kvm-0.12.1.2-2.253.el6.x86_64
# rpm -qa | grep seabios
seabios-0.6.1.2-15.el6.x86_64
geust info:
guest_name: win7_sp1_64bit

Steps to Reproduce:
1.boot a windows guest.
2."start" -> "control-panel" -> "System and Security" -> "Administrative Tools" -> "Task Scheduler".
3.select "Create Task..." and create a task as following:
  in the "General" tab, fill in "Name" and "Description".
  in the "Triggers" tab, new a trigger, set one time and select "enabled".
  in the "conditions" tab check "Wake the computer to run this task". 
4.suspend guest to memeory.
5.wait for the guest resuming from S3.

Actual results:
after the step 5, the windows 7 guest can not resume from S3 as a response for RTC alarm.

The patch was incorrectly removed on seabios-0.6.1.2-15.el6. Reopening the bug.

Reproduced and verified this issue with the following steps:
1.boot a windows guest.
2."start" -> "control-panel" -> "System and Security" -> "Administrative Tools"
-> "Task Scheduler".
3.select "Create Task..." and create a task as following:
  in the "General" tab, fill in "Name" and "Description", check "Run with highest privileges".
  in the "Action" tab, new a action with "Display a message"
  in the "Conditions" tab check "Wake the computer to run this task".
  in the "Triggers" tab, new a trigger, set one time and select "enabled". 
4.suspend guest to memeory.
5.wait for the guest resuming from S3.

Reproduced this issue with the environment and test results as following: 
host info:
# uname -r && rpm -q qemu-kvm
2.6.32-251.el6.x86_64

# rpm -qa | grep seabios
seabios-0.6.1.2-15.el6.x86_64
geust info:
guest_name: win7_sp1_64bit
