Cisco CML Enterprise – can’t access the CML UI for v 2.7 and 2.6

[SJNIII]

I have been working with Cisco Support on this issue for more than a month and they can’t find out what the issue is or how to correct it.  I am wondering if anyone has seen this issue and have any suggestions on a fix.

I have installed Cisco CML Enterprise 2.7.2 build 26 on a vSphere cluster running ESXi 7.0.  The VM was deployed from the OVA and I followed https://developer.cisco.com/docs/modeling-labs/deploying-the-ova-on-esxi-server/

The VM deploys with no issues.
I can connect to the System Administration Cockpit (https://nnn.nnn.nnn.nnn:9090) and login.

However, when I try to access the UI (https://nnn.nnn.nnn.nnn,all I see on the login screen is a spinning blue circle that has the words “Go make some coffee”.

I have tried several things.

First was to deploy Cisco CML Enterprise 2.6.1 on the same ESXi 7.0 host.  The same thing happens with the login to the UI (https://nnn.nnn.nnn.nnn), the spinning blue circle that has the words “Go make some coffee”.

I then deployed Cisco CML Enterprise 2.5.1 and I was able to login to both the System Administration and Cockpit and UI (no spinning blue circle).

I installed the same 2.7.2 OVA on a different a vSphere cluster running ESXi 7.0 on different network and it deploys and I can login to both the System Administration Cockpit and UI.

The only difference I see is for 2.7.2 -- on the cluster where I see the spinning circle, the servers are running AMD processors vs Intel on the other cluster where I see no spinning circle. I told support this and they say it should not affect logging into the UI

What I see is,

On AMD processors, CML Enterprise v2.7.2 and 2.6.1 UI does not work, while 2.5.1 does work

On Intel processors, CML Enterprise UI v2.7.2 does work

Anyone have some ideas or suggestions?

thanks

@SJNIII The only thing i can assume here based on your information is the snip in the release note https://developer.cisco.com/docs/modeling-labs/system-requirements/

> CML is only fully supported when running on Intel processors. While the CML application services run equally well on systems with Intel or AMD processors, some of the bundled reference platform VM images only run on Intel processors. Support for running CML on non-Intel processors will be provided on a best effort basis.

Whilst it does states CML should run on AMD processors, there might be compatibility issues with specific hardware configurations or software versions.

Just guessing here.

Thanks for the reply.  Support has no idea and cannot find a solution at this point. They have me trying various test

I recall one test that may have worked was install 2.5 and then upgrade to 2.6 and then to 2.7. But  I have to go back and check if this did work.  If it did, seems like an odd patch to get to 2.7

I am not sure where the words “Go make some coffee” come from.

Yeah very odd. Might be worth seeing if you can reach out to Ralph Schmied, he’s my go to guy for all things CML and is amazing for this stuff.
