Static DHCP lease never distributed

Hi there, I have a libvirt network defined as so: <network> <name>customers</name> <bridge name='customers' macTableManager='libvirt' /> <port isolated='yes' /> <dns enable='no' /> <ip address='10.0.0.1' prefix='24'> <dhcp> <host mac='02:99:92:43:eb:b8' name='dhcp-test' ip='10.0.0.10' /> </dhcp> </ip> </network> And that network is attached to a virtual machine: <interface type='network'> <mac address='02:99:92:43:eb:b8'/> <source network='customers'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> But for some reason when the domain starts, it never gets an address. If I tcpdump the bridge that was created by the network I can see it sending out discover packets, but dnsmasq never seems to respond: 01:26:25.039987 02:99:92:43:eb:b8 > ff:ff:ff:ff:ff:ff, ethertype IPv4 (0x0800), length 342: (tos 0x0, ttl 64, id 0, offset 0, flags [none], proto UDP (17), length 328) 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request from 02:99:92:43:eb:b8, length 300, xid 0xc7283f76, secs 228, Flags [none] Client-Ethernet-Address 02:99:92:43:eb:b8 Vendor-rfc1048 Extensions Magic Cookie 0x63825363 DHCP-Message Option 53, length 1: Discover Client-ID Option 61, length 7: ether 02:99:92:43:eb:b8 MSZ Option 57, length 2: 576 Parameter-Request Option 55, length 7: Subnet-Mask, Default-Gateway, Domain-Name-Server, Hostname Domain-Name, BR, NTP Vendor-Class Option 60, length 3: "d-i" Despite that appearing to be the correct mac address. Looking in /var/lib/libvirt/dnsmasq/customers.hostsfile, it's returning what I would expect to be there: 02:99:92:43:eb:b8,10.0.0.10,dhcp-test If I add a <range> stanza to the configuration, that does appear to work, so it seems this is only related to static addresses. This is libvirtd 5.8.0.
