tripleo-quickstart deploying VMs as root user doesn't work

[Steven Hardy]

As a developer vs CI user of quickstart, I want the option to deploy VMs not obfuscated by the unpriveliged virt stuff - I'd like them to show up in virt-manager just like instack-virt-setup, then I can easily restart them after a host reboot, and I can easily inspect the primary console in the event of boot issues etc.

Currently this doesn't appear to work:

If you add "ssh_user:root" to your config, it creates the VMs correctly, but then fails like:

TASK [setup/undercloud : Start undercloud vm] **********************************
task path: /home/shardy/.quickstart/tripleo-quickstart/roles/libvirt/setup/undercloud/tasks/main.yml:282
Tuesday 23 May 2017 17:31:42 +0100 (0:00:00.058) 0:06:41.766 ***********
fatal: [tripleodev2.localdomain]: FAILED! => {"changed": false, "failed": true, "msg": "Cannot access storage file '/home/stack/pool/undercloud.qcow2' (as uid:107, gid:107): Permission denied"}

Looking at the playbook, it's looking for non_root_user which is still stack.

Then, I made the mistake of doing:

ssh_user: root
non_root_user: root

This also doesn't work and the attempted cleanup of the non_root_user somehow killed sshd.

Can anyone suggest a simple way we can stand up VMs on the host *exactly* like instack-virt-setup, without any of the unprivileged virt aspects of quickstart?

Tim Rozet may be working on a patch for this bug.

michap pointed to https://gerrit.opnfv.org/gerrit/#/c/28675/26/config/quickstart_defaults.yaml which may be the basis of a working config for re-testing this

This looks like a documentation RFE as well

I found a lot of hard-coded paths in the Playbooks for using "/home/{{ non_root_user }}" and "/home/{{ ssh_user }}" for assumptions of the $HOME path. I have started to refactor the code to support using non-standard home directories which is helpful in the case of using /root. I also changed the "non_root_user" variable to be the "provision_user" to signify that it now *can* be a root user. The "non_root_user" can still used for backwards compatibility.

This work is being done in my fork and branch here:

https://github.com/ekultails/tripleo-quickstart/tree/root_user_support

I am using this TripleO-Quickstart command for testing:

$ bash quickstart.sh --teardown none --no-clone --release trunk/newton -e "provision_user=root" -e "ssh_user=root" -e "undercloud_user=root" -e "overcloud_user=root" -e "undercloud_user_home=/root" --tags all -v 127.0.0.2

Currently I still cannot get this to work and this requires further tweaking. I will be out of town for a few days and would appreciate having some other eyes looking into this. I am still very new to the TripleO-Quickstart project and at least have a strong background with using both Ansible and OpenStack.

    Add example of deploying with privileged virt

    This example is copied from the following opnfv review

    https://gerrit.opnfv.org/gerrit/#/c/28675/26/config/quickstart_defaults.yaml

    It seems to work well for me, I can deploy VMs via quickstart which
    show up via virt-manager and should survive reboots because
    the qcow2 files are stored in /home/stack.
