This cookbook configures OpenStack z/VM driver(including compute z/VM driver and network z/VM agent) on controller node or seperate nodes on x86 Linux system, to enable z/VM cloud for OpenStack.
It supports multi computes/neutron zvm agents in one host.
This cookbook is for OpenStack Kilo version, we suggest deploy to z/VM CMA with cookbook-compute-anywhere and cookbook-external-keystone from Liberty.
RHEL7 on x86
11.10.4 chef or higher required.
The following cookbooks are dependencies:
- openstack-common
- openstack-compute
- openstack-image
- openstack-network
Here is a diagram of z/VM driver in the "Single Controller + N Compute" mode:
| Services | Controller Node | Cloud Node x |
|---|---|---|
| Compute | nova-api, nova-cert, nova-conductor, nova-scheduler | nova-compute(nova-zvm-virt-driver) |
| Network | neutron-server | neutron-zvm-agent |
| Block Storage | cinder-scheduler, cinder-api, cinder-volume |
From Juno release, the z/VM driver cookbook supports multi computes/neutron zvm agents in one host. The releated data_bag also need to be changed. All the xCAT's passwords are in one data bag item. The index "xcat_server" should be same with node['ibm-openstack']['zvm-driver'][host]['xcat']['server'].
An example of user_passwords/xcat.json:
{
"id": "xcat",
"xcat": "admin",
"1.1.1.1": "admin",
"2.2.2.2": "admin"
}
