All, My issue is close to what reported by Emilien and others in https://answers.launchpad.net/quantum/+question/197701. Only difference is that instead of not receiving DHCP reply, I do see the DHCP reply from GW interface, but I still can not ping/ssh to the VM. My server configuration is same as what Emilien has described in his document here https://github.com/EmilienM, the only difference is that I'm using a third interface (eth2) to connect quantum networks on two servers. And the eth1 is used for management traffic.
My network configuration is id IPv4 IPv6 start address DNS1 DNS2 VlanID project uuid 1 10.0.0.0/24 None 10.0.0.2 8.8.4.4 None None 61868ec0fd63486db3dbf1740e7111e9 6f765203-7fd8-425e-92b8-cf72b5c1c6cd I launched VM in network 1 and it is running on the nova-compute server (essex-2), I can see following tcpdump message from the tap interface for the VM 16:19:06.183240 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from fa:16:3e:7f:f1:69 (oui Unknown), length 395 16:19:06.184146 IP 10.0.0.1.bootps > 10.0.0.4.bootpc: BOOTP/DHCP, Reply, length 312 16:19:07.165572 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from fa:16:3e:7f:f1:69 (oui Unknown), length 395 16:19:07.165955 IP 10.0.0.1.bootps > 10.0.0.4.bootpc: BOOTP/DHCP, Reply, length 312 16:19:08.299928 IP6 fe80::2429:e5ff:fed4:8ad5 > ip6-allrouters: ICMP6, router solicitation, length 16 16:19:08.411921 IP6 fe80::2429:e5ff:fed4:8ad5 > ff02::16: HBH ICMP6, multicast listener report v2, 1 group record(s), length 28 16:19:09.143041 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP, Request from fa:16:3e:7f:f1:69 (oui Unknown), length 407 16:19:09.143507 IP 10.0.0.1.bootps > 10.0.0.4.bootpc: BOOTP/DHCP, Reply, length 312 16:19:14.143971 ARP, Request who-has 10.0.0.4 tell 10.0.0.1, length 42 16:19:15.143784 ARP, Request who-has 10.0.0.4 tell 10.0.0.1, length 42 16:19:16.143843 ARP, Request who-has 10.0.0.4 tell 10.0.0.1, length 42 No ARP response from the VM. I tried to login to the VM console by virsh console instance-00000003 so that I can do tcpdump inside the VM. But I got following error message: root@openstack-2:/etc/libvirt/qemu/networks# virsh console instance-00000003 Connected to domain instance-00000003 Escape character is ^] error: internal error /var/lib/nova/instances/instance-00000003/console.log: Cannot request read and write flags together Could some one suggest on how to debug this issue? Thanks Yi PS: my nova.conf files are attached.
