From LAN I can ping and ssh vm instance but from vm instance i cannot ping to home Lan GW, pc host. VM instance can ping up to centos7 virtualbox and openstack Router GW. Instance created with centos and cirros using direct
Hi Team, I have been struggling to get the solution. I'm testing openstack and deploying it over virtualbox. I have shared my issue in SO with help from berndbausch <https://stackoverflow.com/users/3548109/berndbausch> and try to share it here also to get more help....as I have create and redeploy few times with different openstack release.. deployment methods..parameters....still the same problem. I don't think my deployment is different with others as i follow the guideline and common practise... just stuck on this problem...please do help and assist me further. Thank you to all.... Below is my environment setup. Windos10_Virtualbox----Centos7------Openstack----VM instance [192.168.0.0/24] - external network/public-ip Pc host - 192.168.0.160 Home Lan GW - 192.168.0.1 Centos7 - 192.168.0.12 (VM virtualbox) Openstack Router GW - 192.168.0.221 Virtualbox VM setting bridge (enp0s3) and promiscuous mode all selinux permissive add rules icmp and ssh. create public-ip 192.168.0.0/24 (pool 220-230) create router create private subnet 10.0.0.0/24 attach router to private subnet create router GW(public-ip) public-ip and also floating ip. Some instance created with direct public ip and some with private subnet and using floating ip. I have tested with queens, stein, train. With allinone and also using answerfile and all end up I cannot ping external. I follows guideline below:- *hxxps://www.linuxtechi.com/single-node-openstack-liberty-installation-centos-7/ <http://www.linuxtechi.com/single-node-openstack-liberty-installation-centos-7/>* *hxxps://www.rdoproject.org/install/packstack/ <http://www.rdoproject.org/install/packstack/>* This some of answer file parameters that i edited CONFIG_NEUTRON_L3_EXT_BRIDGE=br-ex CONFIG_NEUTRON_ML2_TYPE_DRIVERS=flat,vxlan CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=extnet:br-ex CONFIG_NEUTRON_OVS_BRIDGE_IFACES=br-ex:enp0s3 CONFIG_NEUTRON_OVS_BRIDGES_COMPUTE=br-ex CONFIG_PROVISION_DEMO=n ip netns list qrouter-f6967bba-986e-4bb3-838e-d035a684e2c4 (id: 2) qdhcp-dbd713cd-1af4-4e2c-9c57-d8a675a10608 (id: 1) qdhcp-fa6fb1d6-b65e-4eb2-a4a4-5552fde8bb08 (id: 0) [root@myospackanswer ~(keystone_admin)]# ip netns exec qrouter-f6967bba-986e-4bb3-838e-d035a684e2c4 arp -an ?
