Bah
Apparently this is what happens when you specify an IP outside of the network's dhcp range:
<range start='192.168.124.2' end='192.168.124.254'/>
<host mac='54:52:00:86:01:01' name='kube-1' ip='192.168.122.87'/>
|
Description of problem: I have been using: virsh net-update default add ip-dhcp-host "<host mac='${MAC}' name='${name}-${offset}' ip='192.168.122.$(( $lastoct + $offset ))'/>" --live --config on Fedora 23 to allow hosts to pick up names and allow easy host -> ip lookups by parsing the output of 'virsh net-dhcp-leases ...' However, when I moved the same logic over to 7.2 the hostname is missing in virsh (as well as in the dhcp client on the guests): # virsh net-dhcp-leases default Expiry Time MAC address Protocol IP address Hostname Client ID or DUID ------------------------------------------------------------------------------------------------------------------- 2016-09-09 14:17:52 54:52:00:86:01:01 ipv4 192.168.124.158/24 - - 2016-09-09 14:17:56 54:52:00:86:01:02 ipv4 192.168.124.159/24 - - 2016-09-09 14:18:00 54:52:00:86:01:03 ipv4 192.168.124.160/24 - - despite 'name' being populated in the 'host' entry. # virsh net-dumpxml default <network> <name>default</name> <uuid>2215facb-0f96-40f1-b5d4-28d46675d18d</uuid> <forward mode='nat'> <nat> <port start='1024' end='65535'/> </nat> </forward> <bridge name='virbr0' stp='on' delay='0'/> <mac address='52:54:00:43:4b:30'/> <ip address='192.168.124.1' netmask='255.255.255.0'> <dhcp> <range start='192.168.124.2' end='192.168.124.254'/> <host mac='54:52:00:86:01:01' name='kube-1' ip='192.168.122.87'/> <host mac='54:52:00:86:01:02' name='kube-2' ip='192.168.122.88'/> <host mac='54:52:00:86:01:03' name='kube-3' ip='192.168.122.89'/> </dhcp> </ip> </network> Version-Release number of selected component (if applicable): libvirt-1.2.17-13.el7_2.5.src.rpm How reproducible: 100% Steps to Reproduce: 1. sudo virsh net-update default add ip-dhcp-host "<host mac='${SOMEMAC}' name='test-1' ip='192.168.124.158'/>" --live --config 2. create and start a VM that uses ${SOMEMAC} 3. virsh net-dhcp-leases default Actual results: # virsh net-dhcp-leases default Expiry Time MAC address Protocol IP address Hostname Client ID or DUID ------------------------------------------------------------------------------------------------------------------- 2016-09-09 14:17:52 54:52:00:86:01:01 ipv4 192.168.124.158/24 - - Expected results: Expiry Time MAC address Protocol IP address Hostname Client ID or DUID ------------------------------------------------------------------------------------------------------------------- 2016-09-09 14:17:52 54:52:00:86:01:01 ipv4 192.168.124.158/24 test-1 - Additional info:
