Hello, I am a newbe in openstack. I've installed OpenStack Havana from RDO on single host running Scientific Linux 6.4 using packstack --allinone That is all openstack components are running on single host. I am trying to run test instance cirros-0.3.1-x86_64 through dashboard. As a private network I've chosen 10.0.1.0/24. On dashboard I see that ip 10.0.1.2 is assigned to instance. Instance system log shows:
Starting network... udhcpc (v1.20.1) started Sending discover... Sending discover... Sending discover... No lease, failing WARN: /etc/rc3.d/S40-network failed That means that instance has not recieved ip address from dnsmasq server. As I understand dnsmasq process has to be started up by nova or neutron components and received MAC/IP pair. But no dnsmasq processes were running on host. Then I've started dnsmasq by hand and launched instance again. This time dasboard showed that instance is assigned ip address 10.0.1.2 and instance system log gave this lines: Starting network... udhcpc (v1.20.1) started Sending discover... Sending select for 10.0.1.8... Sending select for 10.0.1.8... Lease of 10.0.1.8 obtained, lease time 43200 ... that is the instance received from dnsmsq different ip address 10.0.1.8 Why is dnsmasq not started automatically by nova or neutron ? Any hints ? The openstack host has such interfaces: netstat -r Destination Gateway Genmask Flags MSS Window irtt Iface 239.2.11.72 * 255.255.255.255 UH 0 0 0 br1 172.24.4.224 * 255.255.255.240 U 0 0 0 br-ex <external net> * 255.255.255.224 U 0 0 0 br0 10.0.1.0 * 255.255.255.0 U 0 0 0 br-int 192.168.1.0 * 255.255.255.0 U 0 0 0 br1 link-local * 255.255.0.0 U 0 0 0 br0 link-local * 255.255.0.0 U 0 0 0 br1 link-local * 255.255.0.0 U 0 0 0 br-ex link-local * 255.255.0.0 U 0 0 0 br-int default <gateway> 0.0.0.0 UG 0 0 0 br0 /etc/neutron/dhcp_agent.ini has: --------------- ... interface_driver =neutron.agent.linux.interface.OVSInterfaceDriver dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq dnsmasq_config_file = /etc/dnsmasq.conf ... --------------- /etc/nova/nova.conf ------------- ... dnsmasq_config_file=/etc/dnsmasq.conf neutron_ovs_bridge=br-int flat_network_bridge=br-int ... ------------- /etc/dnsmasq.conf dhcp-range=10.0.1.2,10.0.1.100,12h Thanks. _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
