[SOLVED] Can opennebula-frontend-5.8 and opennebula-node-host-4.14 versions be used together?

[you-can-change (Just So So)]

For some reasons, the KVM host (centos6.5) cannot be upgraded to centos7.

Centos6 on the official website only supports OpenNebula version 4.14 at the highest level.

I want to deploy opennebula-5.8 with CentOS 7 to manage the KVM host of CentOS 6.5. Is that all right?

When I tried to do this, I added the wrong message when adding the host as follows:
Tue Apr 2 12:11:18 2019 [Z0][ONE][E]: Error monitoring Host host3 (16): ./pci.rb:33: uninitialized constant NAME (NameError)

Haha, my English is not good, the translation from Google.

Hi @you-can-change

In OpenNebula 5.8 only CentOS 7 is supported, so maybe there is a compatibility error with CentOS 6, here you can see all the supported platforms.
