To install Pbench agent on the compute nodes and vm's (i.e client and server),you have to follow the below steps and set the below params install/group_vars/all.yml
`pbench_key_url: <pbench_key_url>
pbench_config_url: <pbench_config_url>
pbench_configuration_environment: <pbench_configuration_environment>`
`cd {{ ansible_user_dir}}/jetpack/install`
1) To create the client and server
`ansible-playbook boot.yml`
2) Install Pbench agent bootstrapping
`ansible-playbook pbench_agent_bootstrap.yml -e "repos=<perf-dept-repo>" `
3) Install Pbench agent install
`ansible-playbook pbench_agent_install.yml`

Why do you have to install perl-Data-UUID?

These will install perl-Data-UUID after the epel is installed on computes as by default the yum repos are disabled

But why is this needed explicitly? The pbench-agent RPM should have dependencies that take care of this.

Why are there two roles that are named the same and seem to do almost the same thing?

There are two tasks for idempotency because
- In the first task it creates Uperf client and server vm, so it uses UUID's of the ports registered in var
port_idsthat were created newly if these ports didn't exist - The second task creates uperf client and server vm's using the UUID of the ports already exist registered in
get_port_idsvar

Why not just have one task handle this?

Why do you need to explicitly install perl-Data-UUID here and not for CentOS 7? Don't you have this requirement elsewhere?

I had seen this requirement in the Pbench installation documentation. But I just checked the doc and can't find it now

The pbench-agent RPM should have its own dependencies. I'd suggest removing this to confirm.

| # Playbook to create client and server vm on Openstack | |||

Can this be factored out into its own PR as it does not appear to be tightly related to pbench agent installation?

This PR supports Pbench agent installation on Openstack Vm's, Computes, and Trafficgen host if enabled. This playbook creates the Uperf client and server vm.

Sure, but this playbook appears to be completely independent of what it is being used for, which makes it verifiable on its own and not tied to anything pbench.
