[ovirt-users] "Could not detect Guest Agent on VM"

[Sven Achtelik]

Hi Tomas,



this is how it looks like in the device Manager:

The Logfile holds some errors and no new errors are generated when I initiate the snapshot. I would like to do snapshots without memory and I believe that this requires some working file system pause. With that message in the GUI it’s hard to trust in this snapshot procedure. Is there a way to see if the FS is paused when I do a snapshot without memory ?



When doing a snapshot without memory I can find these in the Event-Viewer under Application:

Is there anthing that needs to be changed ?



Thank you,



Sven

IF I go and check the Services in those VMs I can also see the "Ovirt Guest Service" running and the "QEMU Guest Agent" running. Also there is Information about the VM show in the GUI, like installed applications etc.. I've tried several Versions of the tools and even with the latest 4.1.5 I can't get that message to disappear.



First check if the virtio-serial driver is properly installed. In Device Manager you should see VirtIO Serial Driver in System devices category.



You should also check the oVirt GA log. Search for ovirt-guest-agent.log, it should be in C:\Windows\SysWOW64.

I'm not sure about this one. I don't think we use QEMU GA (or any other

GA) to freeze filesystems. So this feature should not be affected.
