OS & CPU Tab Fails to Load in Template Creation

Product Support Installation & Configuration
1

When selecting OS&CPU in the Create Template, I just get a blank page in the browser - WHY ?

Early December last year, stopped the PoC because of this, but I thought I would continue this year, and still the same issue.

Tried restarting services, restarting the server. different accounts, different browsers, Edge, Chrome and Firefox

Opennebula 7.0.1

2

Hello Andrew,

We have been checking release 7.0.1, but we are not able to reproduce the error. It would be very helpful if you could provide us with some additional information.

Please open Sunstone in Chrome and open the DevTools console by pressing F12. Once the console is open, click on the OS & CPU tab. An error should appear in the console; please copy that error and send it to us.

Additionally, any details about your environment would be helpful (for example, whether this is a fresh OpenNebula installation, whether you have hosts configured, if you are using KVM, etc.).

Kind regards,

Hello Andrew,

The KVM_CPU_MODELS attribute is not present on one of your hosts, and this is causing the failure. We will fix this in future versions of OpenNebula.

In the meantime, to continue with your PoC, please follow these steps:

  1. Check whether any of your hosts are missing the KVM_CPU_MODELS attribute. You can verify this using the CLI:

    onehost show <idHost>

  2. For any host that does not have the KVM_CPU_MODELS attribute, update the host using the CLI:

    onehost update <idHost>

  3. Add the attribute KVM_CPU_MODELS=“” (with an empty value).

  4. Refresh Sunstone and check the OS & CPU tab again.

Also, could you let us know how the host is configured?

Thanks!

We just installed via minione, so it looks like this

We updated and now have

HYPERVISOR=“kvm”
IM_MAD=“collectd”
KVM_CPU_MODELS=“”
VERSION=“7.0.1”
VM_MAD=“kvm”

and it’s not made any difference

Hello Andrew,

The IM_MAD attribute on the host is not correct; it should be set to “kvm”. Please follow the steps below:

  1. Use onehost update to change IM_MAD to "kvm".

  2. Execute onehost sync --force.

  3. Execute onehost forceupdate.

Please perform these steps and let us know whether the issue is resolved.

Thanks!

We were thinking of uninstalling and re-installing and trying again.
