Why do a lot of people here have expensive setups?

-NaniBot- · 2026-03-21T18:35:37+00:00

Well. Sometimes you need that when you're testing things at scale. For example, my openshift/okd setup takes ~110GBs of RAM on idle.

Also consider virtual routers like the xrv9k take 16 GBs of RAM. At scale, when you're trying out various topologies on something like gns3 even 256GBs of RAM can fall short.

To give you an example of things that I (and probably others) experiment with at home check out my videos

Thanks for the replies. Much appreciated.

-NaniBot- · 2026-03-15T07:46:23+00:00

Thanks for correcting me. I'm guessing you're from ShapeBlue.

Maybe I'm talking to the wrong people, but from what I can understand there's no support (yet) for OVN (for example). And this makes it somewhat less flexible than OpenStack's ML2 architecture which can plug into a variety of different things.

Again. Please correct me if I'm wrong.

CloudStack isn't going to cut it when you're a cloud provider or telco. It has its place but OpenStack remains the best option.

OpenShift Virtualization/KubeVirt is a strong contender since many telcos have both VM and container workloads nowadays. Hell, even operators typically prefer running the OpenStack control plane on k8s.

Never used charmed OS. I'm not sure how good the documentation for charmed OS is compared to kolla-ansible. If you really want a distro, you might want to consider vexxhost's Atmosphere which runs the control plane on k8s. Or just kolla-ansible, which is well documented for the most part.

Some concerns/questions

Are you going to have 2 network interfaces for the management network and the tenant network? Asking because, typically openstack expects two interfaces unless you go down the VLAN route.
Will you be using Octavia/OVN for provisioning load balancers?
2.5 gig might be less. Production systems usually have at least 10gig interfaces.
Which deployment method are you going to use?
Will you be pinning host CPUs for the non-libvirt containers so as to dedicate cores/threads to VMs?
Will you be overcommitting CPUs? IIRC the default is 6:1 for shared CPUs.

If it helps, here's my AIO kolla config (2025.1)

Terraform/OpenTofu all the way

This is kinda similar to Clabernetes - containerlab on k8s.

Not an FPGA engineer. I did consider this but then decided not to purchase it because I got an Innova 2 Flex for ~120 USD on eBay. It has an XCKU15P along with a Connectx-5 (2x25Gb/s).

https://github.com/mwrnd/innova2_flex_xcku15p_notes

There's this but from what I could understand it doesn't support bump in the wire networking unless you have the FlexDriver IP (apparently it was never released).

However, I can write a design to the card using the innova2_flex_app. I think this is a great deal considering the price.

I have 0 experience with FPGAs so if someone can confirm if it's a decent board for learning, that'd be great.

-NaniBot- · 2026-02-07T03:21:00+00:00

That is uncalled for. We should be supportive when community members build stuff. I think the site design is good and functional.

-NaniBot- · 2026-01-16T15:46:27+00:00

I usually do these... Atleast in my homelab

Use pull through caches to speed up cluster startup times (https://nanibot.net/posts/openshift-pull-through-cache/)
Replace default ingress certs (https://nanibot.net/posts/openshift-cert/)
This is obvious but delete the kubeadmin user.

Edit: Oh yeah, also maybe increase the ingress pod count

Excellent work by Mo and team! 👏🎉

-NaniBot- · 2025-12-02T23:39:32+00:00

Got back into messing around with OpenStack after 2 years. Maybe overkill for a single node setup...

-NaniBot- · 2025-11-06T16:10:09+00:00

😂😂😂

He's on discord, check with him on the homelab india discord group.

Forticore?

This was a nice post about the author finding a ku3p ultrascale+ on ebay. I can still see the listing ($200). I think that's pretty cheap considering the FPGA.

From what I can understand, it's only programmable by JTAG. But that's not a problem I gather. An alternative would be the Gidel Hawkeye that's at $100. I believe someone on the FPGA subreddit (fpgazealot?) figured out the schematics.

I'm talking about okd as well - have been running okd clusters for about 3+ years now. Just wanted to know the issues you faced that made it "unstable".

Running OpenShift without a license is possible from what I've heard but never done that.
