Why Proxmox Says “QEMU Guest Agent is Not Running”
If you’ve run into the “QEMU Guest Agent is not running” message in Proxmox VE, you are in luck!
Our experts are here to help you out. This error means the communication channel between your virtual machine and the Proxmox server is disrupted.
The QEMU Guest Agent helps Proxmox to effectively monitor and manage our VM. It offers several features like:
- Performance Monitoring:
Track memory, CPU, disk usage, and network traffic within the VM. - Shutdown/Reboot:
Start shutdowns or reboots of the VM from the Proxmox interface. - File System Synchronization:
Easily transfer files between the virtual machine and Proxmox host. - Time Synchronization:
Make sure the VM’s clock is in sync with the Proxmox host.
Reasons behind the “QEMU Guest Agent is Not Running”
- Not Installed or Enabled:
The QEMU Guest Agent might not be installed or enabled within the guest VM.
- Not Running:
Even if installed, the Guest Agent service might not be running due to various reasons.
- Driver Issues:
Missing or outdated drivers for the Guest Agent within the VM can cause communication problems.
Troubleshooting Tips
- First, go to the VM and log in to the guest operating system. The installation commands depend on the guest OS. For example:
- For Debian/Ubuntu:
sudo apt update
sudo apt install qemu-guest-agent - For CentOS/RHEL:
sudo yum update
sudo yum install qemu-guest-agent
- For Debian/Ubuntu:
- Next, enable and start the Guest Agent service:
- For Systemd (most modern Linux distros):
sudo systemctl enable qemu-guest-agent
sudo systemctl start qemu-guest-agent - For SysVinit (older Linux distros):
sudo chkconfig qemu-guest-agent on
sudo service qemu-guest-agent start
- For Systemd (most modern Linux distros):
- Next, check if the Guest Agent service is running:
- For Systemd:
sudo systemctl status qemu-guest-agent - For SysVinit:
sudo service qemu-guest-agent status
- For Systemd:
- In some cases, a simple reboot can fix temporary glitches that prevent the Guest Agent from starting correctly.
sudo reboot - Sometimes, firewall rules within the guest VM might block communication with the Proxmox host. So, make sure the Guest Agent service is allowed to communicate on the appropriate ports (typically port 22 for SSH).
sudo iptables -A INPUT -p tcp --dport 22 -j ACCEPT
