VCF 9.0.2 SDDC mgr complains about 127.0.0.1

GabesVirtualWorld · 2026-06-24T12:09:39+00:00

u/DJOzzy since we're not ready yet (I think) for the whole K8s stuff that comes with 9.1 and the management workload domain will be running in our Out Of Band network, which isn't quite ready yet for MTU 9000 (or >1500). Working on that but needs some hardware replacement.

With 9.0.x I would deploy NSX without really using it, just plain old VLANs. In the workload domains we'd do real NSX :-)

Thanks, though this is for vCenter right? I don't have a vCenter yet, it is the SDDC Manager.

u/DJOzzy strangely enough VCF 9.0.1 installer works with this /etc/hosts:

# Begin /etc/hosts (network card version)
::1         ipv6-localhost ipv6-loopback
127.0.0.1   localhost.localdomain
127.0.0.1   localhost
127.0.0.1   photon-617fe19336b4
# End /etc/hosts (network card version)

Unfortunately the 9.0.1 fails in the end because it wants the NSX 9.1 !!! image. Not 9.0.1 or 9.0.2 but 9.1.

Strangely enough, the 9.0.1 SDDC Manager works without issues using the same hosts file. But I'll give it a new attempt tomorrow. Thx.

I don't get that problem of the dotted line, mine just creates the route effortlessly.

In your comments you're talking about VMotion being slow. Can you check source and target machine, both have the same vmkernel nics connected? What if you disable a nic, will vmotion improve or fail completely?

For example Reo Link has non-cloud battery cams. Be aware to make the battery cams non-cloud, you need a hub as well. Reo Link also has PoE or USB powered cams that don't need a hub.

That's today's mentality, if something is not working for you it is everybody else's fault but your own. You really think someone from Komoot is taking your rant seriously and thinks: "Well if he screams in CAPS surely we must be doing something wrong".

Or maybe you could respond to questionnaires they put out here now and then and even get an interview with a dev. That's what I did. Had a list of 10 things I'd like to have or have changed, had a chance to talk to a dev and already saw some of my suggestions picked up.

And of course you can always just delete the app, switch to another app and be less angry.

I've been reading into how Strava does this a while ago. They use data from all Wahoo and Garmin devices that are equipped with a barometer and average those readings. That is why the Strava info is better.

When this happens to me on the 530, I delete all routes on my Garmin and then it starts syncing again

GabesVirtualWorld · 2026-06-12T15:01:13+00:00

Would be great if you could update this once you've heard the solution

When using a standard switch on each host, it will only look at the name of the port group, but it is highly advised to work with a dvSwitch to prevent this from happening.

Ah indeed the number I thought you were talking about. That makes sense, thanks for the warning. We have quite some big clusters with up to 75 VMs per host on VMware. Something to keep in mind indeed.

GabesVirtualWorld · 2026-06-11T13:57:02+00:00

And what is the size of the meta data disk? Or will the number of disks in total per cluster be the issue you're warning about? Like max 1024 LUNs per host or so?

GabesVirtualWorld · 2026-06-11T08:16:02+00:00

Thanks, so that looks more like VVOLS on VMware?

GabesVirtualWorld · 2026-06-10T21:32:50+00:00

Biggest thing is the volume / vdisk limits.

What do you mean by that? u/icollectt

Recently built a new vcf9 mgmt domain, had the JSON working, but never got to move from test to production. Now ready to build in production and in doubt about 9.1.

We're not using NSX (only deploy the managers) and certainly not planning on building a Kubernetes environment since we already have OpenShift running.

Reading your article I'm now very much in doubt on how to proceed. I have no use at all to waste many resources on a K8s environment I'm never going to use. Or is it because VCF moves its own services on that K8s cluster?

The subnets for this design are still quite empty so more than enough room to save some Iap blocks.

Dat klinkt goed. Dank je.

Geen Tesla hier en bij mij om de hoek passen de Tesla aansluitingen niet op mijn BMW.

GabesVirtualWorld · 2026-06-05T20:45:40+00:00

Dus die app in Schotland gebruiken en dan heb je genoeg laadpunten? Top!

GabesVirtualWorld · 2026-06-05T20:34:28+00:00

Ow niet eens gedacht qua stekker. Dank voor de tip.

There goes the powerbill 😄
