I installed Fuel using multi node (no HA) deployment and PXE booted my controller,compute nodes. Verify network was succesfull.After which when i clicked deploy changes, centos got installed in both the nodes. During openstack installation in controller node, I lost connection with controller node from fuel via admin network. I am using controller node as a virtual machine in virtualbox.
I have only one interface in my controller node in which I have admin network connected to physical port of my controller node and other networks (private,public,storage and management) connected using VLAN. Also, I dont have internet connectivity in Controller node. Internet connectivity is only available in Fuel.
Controller node networks:
*Admin network (PXE, eth0) - 10.4.16.0/21
Public network (eth0.100) - 172.16.0.0/24
Mgmt network(eth0.101) - 192.168.0.0/24
Storage network(eth0.102)- 192.168.1.0/24 My default gateway is 10.4.16.1*
Fuel master networks:
Admin network (PXE,eth0) - 10.4.16.0/21
External network (eth1) - 192.168.0.0/16
After the openstack installation started, my default gateway was changed to 172.16.0.1 and i lost connectivity with Fuel. Could anyone please give some advice to solve this problem. Also, please let me know whether its mandatory for controller node to have internet access ?
Thanks in advance!!!
