February 19, 20242 yr Hi everyone, Quote docker: Error response from daemon: driver failed programming external connectivity on endpoint lancache-dns (c4af6531e9ae67e9ea29ab158d435ee6fdccbc54f502488fdad71c1062aeae4a): Error starting userland proxy: listen udp4 0.0.0.0:53: bind: address already in use. Is there a way to modify /etc/libvirt/virt*.conf to disable dnsmasq? As i only use VMs connected to my network anyways and therefore do not need DHCP and DNS services internally.

February 19, 20242 yr Author Solution I ended up disabling autostart of the default network, as suggested here. virsh net-autostart --disable default I want to mention this from the same mailing list, as unraid desperately lacks important network management features for vms, which would make handling those issues much easier: Quote Any network defined with <forward mode='nat'>, <forward mode='route'>, or no forward element at all, will result in libvirtd creating a new bridge device for that network. If the network also has an IP address defined, then a dnsmasq instance will be started, listening *only* on that IP address (i.e. only on the bridge) for DNS requests. If the <ip> element also has a <dhcp> section, then the dnsmasq instance will also listen on the dhcp port *only* on the bridge. For <forward mode='bridge'> and <forward mode='hostdev'>, no bridge device is created by libvirt, no IP address is configured on the host, and no dnsmasq is started.
