Hey every one,

I need of your help  

 

I have a problem with Guest Agent 

 

I can't connect to VM with VNC since some days. 

I have this error on Libvirt log  : 5627: error : qemuDomainAgentAvailable:8610 : Guest agent is not responding: QEMU guest agent is not connected.

At the end of july, I successed during 2 weeks to use WIN11 VM RDC (Remove Desktop Control). However, one days, impossible to connect to VM. I may have changed some settings but I don't know witch one.

 

I have attached the diagnostics file 

I didn't find a solution on internet

I tried to :

- reboot NAS

- delete Libvirt volume and create a new one 

- create new VM Win11 and Win10 with i440fx and Q35 config 

Win 11 Config : 

 

Libvirt config : 

 

Thanks for you help 

 

Ps : I'm sorry for my not perfect English 🙂

I also get the same error。

I also get the same error.

The guest agent error message is not a problem. It is used to get the IP addresses of the guest VM but requires you to install the guest agent on the VM.

 

I did look to see if the message can be suprresed but not found a way to do it yet.

Any update on this? I'm having the same issue running the latest version 6.11.0.

 I also have this problem on Unraid 6.11.1 . Any update on this ?

Guest agent error is not a problem but I am working on an update.

Hi @SimonF,

 

Thank you for looking into this. 

 

The problem is that when this happens I am unable to remote onto the VM. The apps hosted on the vm are unresponsive, and i need to do a force shutdown and start it again in order to get it working. Are you saying that the 2 are unrelated? 

 

Thanks,

George

Yes guest agent is only actioned when in the vm tab to get the ip address on the guest.

Hi,

This week, I had some network problems and I had to reinitialize the network configuration.

At the same time, I update unraid (6.11.1) . That resolved the problem, yesterday I succeed to connect on VNC 

I tried with WIN11 VM.

However, I don't if the update and reset of network config are the solution.

Ok, so its not the agent causing the VM to freeze. 

I have removed the Nvidia GPU passthrough to see if it is more stable that way. 

If that is the cause I will drop logs and diags here and see if anyone can help. 

 

Thanks,

G

The PR to fix the error message has been merged so will be in the next release.

 

IP will now show following output

 

Guest not running

Guest agent no installed

IP addresses

 

Turns out the problem was the GPU passthrough. Having plex on the vm with a gpu did not work well. I moved plex on docker and used the nvidia driver plugin and now plex is rock solid. I delete the VM as it was only running plex. I dont  know why it was freezing before but as it works with docker i'm gona drop it and see if it happens again on another vm with a gpu. 

I have created a new PR to stop the tainted custom-ga-command log enties.
