Hi all,

I'm trying to set up a test CloudStack installation, using two very basic
CentOS 6.8 servers (I previously tried with CentOS 7, but ran into the same
issue, so now I'm trying CentOS 6).

Basically I can get (almost) everything working, except for the *Add
host* stage,
where I get the error "Incorrect details for private Nic during
initialization of ServerResourceBase" in the agent.log.

I haven't edited the agent.properties file manually at all, I have followed
the KVM agent configuration guide
<http://docs.cloudstack.apache.org/projects/cloudstack-installation/en/4.9/hypervisor/kvm.html>
perfectly as far as I can tell, as well as the Management Node
configuration guide
<http://docs.cloudstack.apache.org/projects/cloudstack-installation/en/4.9/management-server/index.html>
.

I have cloudbr0 and cloudbr1 bridge interfaces set up, as well as eth0
which is the actual IP I'm connecting to.

The only other thread I can find where someone had this issue, they ended
up downgrading the agent, does that mean this is a known issue with 4.9? (
https://www.mail-archive.com/users@cloudstack.apache.org/msg20717.html)

Does anyone have any idea why I'm getting these errors? If there's any
other logs / config files you need, please let me know.

Thanks in advance.
