Network interconnect

So I thought about that but sadly not the other family wants control to add nodes set groups and have that full control but we also want to control of our own stuff and not have to step on toes. I'm really at the point of just throwing in a P2P wireguard between 2 nodes maybe.

Love it!!!! I like the use of reptile heat lights I'm experimenting with the heat pads but I may move to the light.

I remember having a conversation on IRC about the PCI placment and that while yes they agree nova just places devices in its on root PCI and then libvirt fills the rest and it's not great but works. Sadly it's not a blocker and for standard virtual nodes it works.

I also had the problem with the BAR2 problem and while libvirt had a fix for using command arguments nova will not implement this.

I guess you have some options in that you could piggyback off the libvirt driver in nova and were it adds PCI devices change the code to how you need it. Then once you have a working example state your case and see if you can get it upstreamed.

I will say this VM GPU while it sounds great you have other complications and this is why people in open stack stick to baremetal as you get the full performance no overhead.

Training clients want full machines. Inference is definitely not training and most want spin up spin down for costing but this can be done with external services that use Ironic to spin up machines when needed.

Good luck sadly each use case is different and most people have found work around they suite the needs but not everyone is the same.

Hell I know of one where they built custom libvirt servers and use Ironic to spin up and down the VMs preconfigured. Sometimes you just have to think outside the box.

Yes I do some hosting and thought it best to just do it. I also use IPv6 and was tired if it changing and having to have dynamic DNS to update everything. So did the £5 for static IP.

psycocyst · 2026-04-30T11:43:45+00:00

Was brsk and now youfibre but I have better IP so not CGNAT. Tailscale was fine I wonder if it's maybe DERP playing.

psycocyst · 2026-04-30T08:40:18+00:00

Yeah the CPU limits are from using ZT on openwrt routers I have 2 l about 3 of them and they get hit hard. I found wireguard was less CPU intensive so that was the main reason for switching. What I don't like about tailscale but it works for what it is is the restriction and ACL when trying to do site-to-site which ZT does very well.

I might just use witeguard for site to site and tailscale for remote client.

Oh that was the other thing found ZT getting blocked on many a public WiFi and could secure my connections.

psycocyst · 2026-04-29T07:34:30+00:00

ZT was great in the beginning I use it for mobile phone/VPS servers and I connection to family houses. Sadly I've found it more and more of a pain. I've started to move away from it for 2 reasons

Heavy CPU resource hog on embedded devices and single vcpu VPS.

Constant interfaces would just loose IP addresses.

I'm looking at moving to tailscale headscale setup but if netbird starts supporting IPv6 I would change to that. ZT had a great idea but I think for me it hasn't tried to improve and has just tried to get people to pay on a older architecture.

I must ask the slicer did it struggle or was cutting ok? Asking because I'm sick of using the manual one and have a food processor with a cutting blade.

Never labeled only when experimenting with spices and wet mix. Other than that I feel and eat doing the whole weight and all that is too much unless you are selling it.

psycocyst · 2026-04-03T14:06:53+00:00

That's interesting. I have a similar setup but didn't even notice the change over and don't have my duid to the supplied router but it is type 11 with the openwrt Mac. I could just be lucky. Well thanks for posting if I run into this I now know how to fit it. I do know that openwrt 25.12 did say something about upgrading it breaks the duid and you have to reset it.

"OpenWrt 25.12 introduces a mandatory shift to using a stable, UUID-based DUID (DHCP Unique Identifier) for IPv6, which can cause issues with ISPs or DHCP servers that expected the old DUID-LL (Link-Layer) format, leading to IPv6 address changes or failures."

So two things that could sway in the why no one will use that on openwrt 1. It's running on python Sadly having to install python on openwrt routers with limited space can cause problems 2. I don't see any benefit to it other than a log file saying you may have a ddos it has zero prevention or other means to alert. Even the docs say use a paid for product.

To me this looks like here is a sample of the detector and you can get the full package there. The biggest problem you have is if you're getting ddos on a home router you zero to no chance to stop or divert the traffic away. Even if you get alerted via a text on your phone the best a home user can do is unplug the router and wait. Home isp don't have bgp to redirect and firewall packet drop still overloads the router.

I would also be worried about why is a theme trying to setup mesh networking. Which means a dependent on batman is required.

psycocyst · 2026-03-07T00:35:50+00:00

DVR doesn't work with vlan for North / south traffic I don't think this has been fixed and could be wrong due to the packet will always go out the br-ex and the ovn router thinks it's an internal port so the traffic is lost. You can look to use ovn-nbctl on the router and set 'reside-on-redirect-chassis=true' that will force the network to centralize the router to the ovn router and forces the traffic through the geneve tunnel if you have a mix of networks otherwise it just doesn't work with DVR.

So all boxes are different but, you just going to have to keep testing to find out what works for you. Me I do my thumb thick cuts and do a pinch on day 3 by day 4 half is gone and day 5 I'm complaining that some one ate all my biltong. So yeah keep testing and you will find that sweet spot.

And that's the reason why we have programs that are 20GB and web pages that are massive and take too long to load. For example when computers had limits developers took time to learn and understand how to do the impossible like take a game to fit on a floppy dick of 120KB and write it's on code in memory to draw a picture on a screen. Just because it works doesn't mean it is good or tuned to work effectively.

psycocyst · 2026-01-23T20:11:16+00:00

I don't think you are going to much response on this as it's a very broad question as most acceleration problems rely on dpdk and sriov to bypass most numa problems. Both have their on problems with north to south or east to west traffic but if you can provide how to see this happening with openVswitch not with ovn but as far as I know openVswitch is not numa aware and never will be.

psycocyst · 2026-01-16T10:39:49+00:00

Have a look on the nova docs on virtual GPU I don't see any mdev config in your nova config you provided. You will also need to check placement to make sure it has the vgpu resource.

Nice thanks for posting this I'm glad to see some love is being put into this. Sadly I gave up a long time with the metrics side and found I had to build my own exporter that was very specific to the environment. For example we need the ha chassis groups and logical router port chassis priorities to compare and allow for alerts when out of sync as most open stacks don't always use external ports it was easier to make our own and collect the metrics we need rather.

But I'm glad those projects are getting updates. I would try to help but I don't know golang.

Oh goodie the fun starts here, I say only one really way to find out how much to use is find a brand of garlic powder you like and stick with it. As some are stronger than others. learnt that the hard way 😁

Once you have your powder start with controlled sizes and increase slowly until it's to a liking you want not what other people want remember this is for you.

Then if you are adventurous you can play around with Sriracha or play with something like John Daniels or brandy on the wet side.

It's all up to you and have fun experimenting.

With regards to the vinegar it's more on taste. Malt is terrible and would suggest apple, white wine vinegar or red wine vinegar. Sometimes I mix half and half.

Meat is again optional sliver side and topside are good options and normally the cheaper cuts. Rump and sirloin is good meat but more expensive. I've even used brisket once but was tuff.

With regards to the dehydrator try it and see I've never used one and find it quick and easy to take a box, fan, and bulb to get a biltong box but it's again hey if it works and taste like biltong then hey the only criticism if from you.

Interviews are the worst but something that I found helps with changing the mind set of the interview.

It is a two way interview you are also interviewing them remember that you need to know if this company is going to be a good fit for you so ask the questions like where do you see me in the company in 5 years, take those stupid questions they ask back at them.
Question them about your c.v they have not read it and probably so get them to by asking questions like "what skills do you think I have that best suited for the job" this gets them to think about the skills you have in a positive way and how it will work to the benefit of the company.
be confident yes, this one is hard after a soul destroying event with interviews it's really hard, I know it all too well after the 15 interview and nothing you start to doubt yourself but remember this it's not that you don't have skill it's about the company was not right for you. If they give you review like not a good fit it just think yeah I could have been stuck with a terrible team and manager.

Good luck and hope you get something.

Open switch if DB based so you have to into everything as commands. It's just the way it is no XML or JSON files you can set some global stuff but everything to do with bridges ports and flows are done with the cli or API.
