I'm trying to use the QEMU guest agent in a headless Debain 10 server. I am getting this error: Dependency failed for QEMU Guest Agent

Can anyone help please?
 
Hi,
where exactly does this error message show up/what command did you use?

Please show us the output of systemctl status qemu-guest-agent.service and/or journalctl -xe, which should contain the actual error message.
Have you enabled agent in the vmid.conf (could you post the vmid.conf?) and/or "QEMU Guest Agent" in the Proxmox Web UI for this VM?

When you say "restart", did you stop the VM and start them, or did you reboot them, because, as mentioned above...

Its red. This mean its not yet applied. Please stop the VM and start again. (a reboot is NOT enough)

did you install the guest agent on the host? That's not what you want. You need to install the guest agent within the VM.
 
i did it before i create Vm

# apt-get install qemu-guest-agent
Reading package lists... Done
Building dependency tree
Reading state information... Done
qemu-guest-agent is already the newest version (1:3.1+dfsg-8+deb10u8).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
 
You need to do it after creating the VM inside of the VM.
 
What?
I should create VM for ex. 100 and after that i should

# apt-get install qemu-guest-agent

after that i check enabled on quemu agent?

next start VM ex. 100?
 
Installing the guest agent on the host does not have the desired effect. Start up the VM, and use the install tool of your VM to install the guest-agent in the VM. See also here.
 
Its red. This mean its not yet applied. Please stop the VM and start again. (a reboot is NOT enough)
This needs to be added to the qemu-guest-agent wiki page along with setting the Option for the Agent to be checked on.

Troubleshooting this when that information should obviously be in the installation help is annoying as it's very specific to Proxmox, not libvirt.
 
Keep seeing this error pop up now and again. Just for reference.

Once the qemu-guest-agent is installed within the Debian 10 guest. You need to enable the agent in the Guest's Options area in the Proxmox admin web interface.

Stop - Start the guest and all should be well.

As my experience you have to enable the agent WHILE the vm is off; if you enable it while running the "Enabled" label is red even if you stop and start the VM. I had the same issue and stopping the VM and disabling saving and enabling again the parameter it worked.
As I saw if you modify ANY parameter while the VM is active doesn't work even if you stop and start it. (using the "free" version)
Hope it helps even if very late.
