-

i have set devstack 2 virtual routers. 1 of routers has external ip 172.24.4.4 , internal ip of 10.10.6.1 have private cloud in 10.10.6.0/24 network. have spawned vm in cloud ip 10.10.6.3 have set floating ip: 172.24.4.5 however, unable ping floating ip. also, noticed unable ping vm 10.10.6.3 neutron. output:

sudo ip netns exec qrouter-74759db2-9044-46eb-a32a-325995b88cf9 ping 10.10.6.3 ping 10.10.6.3 (10.10.6.3) 56(84) bytes of data. 10.10.6.1 icmp_seq=1 destination host unreachable 10.10.6.1 icmp_seq=2 destination host unreachable 10.10.6.1 icmp_seq=3 destination host unreachable 10.10.6.1 icmp_seq=4 destination host unreachable ^c --- 10.10.6.3 ping statistics --- 5 packets transmitted, 0 received, +4 errors, 100% packet loss, time 3998ms pipe 3

i spawned cirros vm , found not able ping gatway 10.10.6.1 worked last time around , time, not sure changed. icmp security rule in place.

please let me know if need other info. please me on this.

  • check if dhcp agent working fine:

get in vm , make sure ip 10.10.6.3 on ethx.

  • check if openvswitch agent working fine:

gateway device owning ip 10.10.6.1 (qr-xxxx) , device linked vm (qvoxxxx) should in same vlan. use command "ovs-vsctl show” find out vlan tag of device.

  • check security group working fine:

use tcpdump capture packets of device tapxxxx , device qvoxxxx. if packet show in device qvoxxxx , not in device tapxxxx, it's filtered security group.
