[ovirt-users] Re: Use local ansible to talk to engineVM and other vm
Thank you. I am running a self-hosted engineVM, and having difficulty
connecting the dots so ansible can talk to vms within the self-hosted
engineVM.
Below is my setup-
inventory dir with files
*cat ~/ansible/inventory/prod/hosts*
[ovirt]
ovirt 192.168.1.100
*cat ~/ansible/inventory/prod/ovirt.ini*
[ovirt]
ovirt_url = https://*engine.ovirt/*ovirt-engine/api # this is self
hosted engine. so invoking ./ovirt4.py fails with http error as physical
host is 'ovirt' but self-hosted-engine fqdn is 'engine.ovirt'
ovirt_username = admin@internal
ovirt_password = password
ovirt_ca_file = ca.pem . # this sits on my local machine
running ovirt4.py standalone fails as mentioned above.
*cat ~/ansible/playbook.yml*
--- name: Talk to self-hosted-engine server
hosts: ovirt
tasks:
- name: Hello server
debug:
msg: Hello server
--- name: Talk to self-hosted-engine VM
hosts: status_up
tasks:
- name: Hello vms
debug:

*ansible-playbook -i ~/ansible/inventories/prod playbook.yml # prod
folder has .ini, .py and static hosts file as above*
PLAY [Talk to self-hosted-engine server]

}

PLAY [Talk to self-hosted-engine VM]
**
*skipping: no hosts matched*
PLAY RECAP
ovirt : ok=2changed=0unreachable=0failed=0
Is there something i am missing?

[ovirt-users] Re: Use local ansible to talk to engineVM and other vm
Thanks. Is there a way to use an existing inventory file? I asked because the server where the engineVM is running is listed into my existing a ansible inventory file on my local machine, but how do I specify/run the subsequent tasks which I want to run on vms running on engineVM as I don't see the /etc/hosts file updated where engineVM runs. How would my local ansible playbook know which vms are available, etc?

[ovirt-users] Re: First host within Self-Hosted engine stays in non-responsive state
I see, which one specific step during the hosted-engine-setup option, is it
1st or the 2nd question I need to set value for?
1. Please provide a comma-separated list (max 3) of IP addresses of
domain name servers for the engine VM
2. Add lines for the appliance itself and for this host to /etc/hosts on
the engine VM?
thank you.
