Hi, I just upgraded to Debian 13 and observing an issue related to libvirtd service. It happens during up time, the service is initially  running and all is working fine. I can run virt-manager and use VMs. Then close virt-manager. After some time (5min), here is what happens : - virt-manager keeps on "Connecting... " when launching it. - "sudo virsh net-list --all" command hangs and does not respond. I have to type Ctrl-C. At that step, I need to restart the libvirtd service : "sudo systemctl restart libvirtd" Then everything is back and running as expected... For 5 minutes as issue comes back. All logs here : https://pastebin.com/qHQWLF4i -=- Versions used : sudo apt policy qemu-system Installé : 1:8.0.2+dfsg-3 sudo apt policy libvirt-daemon-system Installé : 9.5.0-1 $ sudo apt policy virt-manager Installé : 1:4.1.0-2 Can you help here ? Thanks and regards, Pascal
