OK...So, If I apply some patches to Fuel and rebuild Fuel ISO, can I deploy with mixed (x86 and aarch64) targets in Pharos POD? If so, can you please point me to those patches?

Not using any hybrid POD (with combination of x86 and ARM machines as nodes). Right? Regards, Srikanth.

First, note that Pharos specs require 5 nodes, which depending on the scenario can be used as 3 controllers + 2 computes, or 1 controller + computes. This makes it hard to mix x86 and ARM targets in a Pharos POD. Therefore, this is not supported by OPNFV Danube 3.0 Fuel - it is not impossible, but it is out of our current scope. To add some complexity to that, we have the additional jump server host, which used to be x86 up to and including the Danube release cycle; starting with the E release, Armband only support all-AArch64 PODs, including the jump host. Also note that the old Fuel (used up to and including Danube) was replaced by the new Fuel, based on Mirantis Cloud Platform (MCP), which on its own means a lot of changes in the way we build and provision the OS images (bootstrap and final image) on the AArch64 nodes. Starting with the E release, there is no more bootstrap building, all images (Ubuntu Xenial) are fetched from official Ubuntu Cloud Archive (UCA) repos and used as-is. As for old bootstrap building, x86 instructions still apply [1], with only one extra arg required (--target_arch=arm64). To summarize, I recommend looking into the current Armband/Fuel codebase (master branch) and prepare for using MCP-based Fuel instead of the old Danube codebase. To add a lab in OPNFV, you will need 6 x AArch64 nodes (5 for the cluster and one for the jump host).

For that, I am using OPNFV Danube 3.0 release (Fuel ISO). Is it possible to deploy an OpenStack setup with x86 machine as OS Controller and ARM machine as OS Compute node? And also, can anyone give me some reference links to build a bootstrap image (for Fuel deployment) for baremetal ARM machines? Regards, Srikanth.
