I added a host definition to a network definition: <network> <name>Lokal</name> <uuid>2074f379-b82c-423f-9ada-305d8088daaa</uuid> <bridge name='virbr1' stp='on' delay='0' /> <ip address='192.168.180.1' netmask='255.255.255.0'> <dhcp> <range start='192.168.180.128' end='192.168.180.254' /> <host mac='23:74:00:03:42:02' name='somevm' ip='192.168.180.10' /> </dhcp> </ip> </network> But due to the wrong if-statement the argument --dhcp-hostsfile doesn't get added to the dnsmasq command. The patch below fixes it for me. diff --git a/src/network/bridge_driver.c b/src/network/bridge_driver.c index 7d43ef5..4c64a74 100644 --- a/src/network/bridge_driver.c +++ b/src/network/bridge_driver.c @@ -524,7 +524,7 @@ networkBuildDnsmasqArgv(virNetworkObjPtr network, goto cleanup; } - if (networkSaveDnsmasqHostsfile(ipdef, dctx, false) < 0) { + if (networkSaveDnsmasqHostsfile(ipdef, dctx, false) == 0) { virCommandAddArgPair(cmd, "--dhcp-hostsfile", dctx->hostsfile->path); }
