![]() With this interface configuration, the restriction in AWS will hit the OpenStack networking. Edit the /etc/network/interfaces file to contain the following:.Replace INTERFACE_NAME with the actual interface name. We will configure the second interface as the provider interface. The provider interface uses a special configuration without an IP address assigned to it. In this case, we will configure the external interface (NIC) with a special type of configuration. While configuring Neutron networking, we will be creating a virtual bridge (br-ex) for the Provider Network where all the VMs traffic will reach the Internet via external bridge followed by the actual physical NIC (eth1). You may be wondering if the above restrictions will impact the OpenStack setup on AWS EC2. Also, the MAC address and the IP address are tightly mapped, as the AWS environment will not allow the packet to flow if the MAC address registered for the given IP address is different. LimitationsĪn AWS environment will allow the packets to flow in their network only when the MAC address is known/registered in the AWS network environment. This blog post outlines those limitations and their solutions to run OpenStack on top of AWS EC2 Virtual Machine. However, unlike usual nested hypervisor setup, installing OpenStack on AWS EC2 instances, we will have to bypass a few restrictions for the OpenStack setup to work properly. Installing OpenStack in a nested hypervisor environment is not a big deal when we use the QEMU emulator for launching virtual machines inside the virtual machine. ![]() Yes, you read that correctly! This post will show you how to install OpenStack on top of AWS EC2. ![]()
