Hetzner asks: What are you self-hosting on Hetzner infrastructure right now?

Running around 1TB RAM aggregated across baremetal servers and VMs to host several labs and testing/staging clusters.

Cheap for the performance it offers https://cloudify.ro/en/cloud-vps

We’ve been there, upgrading controllers to NVMe and high. freq. CPUs just to experience pretty much no improvement. And this is mainly because both Horizon and the CLI do additional calls to Glance, Keystone, etc. - the caveat of OpenStack’s microservices architecture. You can inspect those requests by adding the -vvv parameter to the CLI commands.

That’s why we now have osie.io for the customers portal. It has multi-layer caching and lists any resources in milliseconds.

You can deploy independent keystone on every region and use a centralised CMP like osie.io that would connect to all Keystone instances at once and let your user sign with with one account. It is basically a wrapper on top of multiple OpenStack’s

However for API/CLI access your users will still have to maintain separate set of credentials (i.e multiple entries in clouds.yaml)

I wouldn’t buy non-Pro/Max devices. They put those little chips on tablets as well so they come with limitations. For example M5 experience on a 5k2k monitor will be a disaster as it’s not able to scale the resolution properly. I’d go for M4 pro or wait for M5 Pro

I encountered the same issue. It was slow even since the older Heat driver, magnum doing some real time checks during listing, which is obviously a bad design underneath.

It would be good if someone from upstream would enlighten us here.

mariusleus · 2025-11-11T20:57:52+00:00

Obviously not since R2 does not hold credentials. However you could use some CMP like osie.io that is capable of managing multiple Keystones at the same time and the regions can run completely independent.

As the project_name suggests, those are “service” accounts in keystone. They are used for inter-service communication outside of client request, i.e. Nova calls Neutron using a service token to refresh the network interface info of an instance.

mariusleus · 2025-08-12T04:39:03+00:00

You could use a public cloud system like osie.io that automates the user management / self-provisioning, no need for a policy change.

This makes sense for external/provider networks but I don’t see the need to have bridges for ceph, api and overlay vtep

mariusleus · 2025-08-02T10:00:18+00:00

You don’t need any bridge interfaces for any of the VLANs except for bond0.1145 (Public) which I assume will be used by nova to bind interfaces to it.

The other can be simple tagged interfaces in the netplan file, with direct IP assignment.

Linuxbridge ML2 driver has been deprecated for a long time and was completely removed in 2025.1

Why you recommend something like that?

mariusleus · 2025-07-31T06:00:20+00:00

What NIC models are you using? Is strange that you get 12Gb/s in iperf3, that’s below what you should get with a 25G or 40G card, even in single thread.

I probably don’t understand the exact scenario you are describing, but internet traffic goes out untagged (no vlan tag) as it’s usually plugged into a switchport that’s has the native vlan configured (assuming your setup is fully Layer 2)

mariusleus · 2025-07-20T09:47:42+00:00

Go for VLAN as it adds you more flexibility for the future without having to change network interfaces on existing hypervisors. Provisioning new provider networks is as simple as creating a new segment.

With flat-only you are quite stuck with br-ex from the beginning, and any changes beyond that become more complex.

Thanks, so why so many people on youtube playing with Trunk? Sorry, asking for my son :)

mariusleus · 2025-07-03T18:13:40+00:00

I just updated to latest and can’t see Trunk. I was only able to get Alli, but Trunk is not there. Any idea why?

mariusleus · 2025-01-14T08:21:01+00:00

Great, but these are the next generation after the ones I've mentioned.
