NAME

NCM::Component::OpenNebula::AII adds AII hook to generate the required resources and templates to instantiate/create/remove VMs within an OpenNebula infrastructure.

AII

This section describes AII’s OpenNebula hook.

SYNOPSIS

This AII hook generates the required resources and templates to instantiate/create/remove VMs within an OpenNebula infrastructure.

RESOURCES

AII setup

Set OpenNebula endpoints RPC connector /etc/aii/opennebula.conf

It must include at least one RPC endpoint and password.

To connect to a secure https endpoint for example you can set the URL endpoint and CA certificate location:

url=https://host.example.com:2633
ca=/etc/pki/CA/certs/mycabundle.pem

By default ONE AII uses oneadmin user and port 2633.

It is also possible to set a different endpoint for each VM domain or use a fqdn pattern as example:

[rpc]
password=
url=https://localhost/RPC2
ca=/etc/pki/CA/certs/mycabundle.pem

[example.com]
password=
user=

[myhosts]
pattern=myhos\d+.example.com
password=
url=http://example.com:2633/RPC2
