Hi,

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 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. But i have admin ip set in br-fw-admin interface (but not able to ping Fuel via admin network). 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!!!
