The main advantage is that virtio-scsi honors TRIM so that deleting files
and/or docker images inside the VM now frees disk space on the host by
resparsifying the qcow2 file.

Doing a `bin/cluster create libvirt …` fails with the following error:
```
TASK: [Warn user about bad openshift_hostname values] *************************
[lenaic-node-compute-cf3fb, lenaic-node-compute-f39d3, lenaic-node-infra-0407f, lenaic-master-fc5f9]
The hostname "lenaic-node-compute-cf3fb.example.com" for "lenaic-node-compute-cf3fb.example.com" doesn't resolve to an ip address owned by this host. Please set openshift_hostname variable to a hostname that when resolved on the host in question resolves to an IP address matching an interface on this host. This host will fail liveness checks for pods utilizing hostPorts, press CTRL-C to continue.:
```
because the `/etc/hosts` of the VM is containing:
```
[openshift@lenaic-node-compute-cf3fb ~]$ cat /etc/hosts
# Your system has configured 'manage_etc_hosts' as True.
# As a result, if you wish for changes to this file to persist
# then you will need to either
# a.) make changes to the master file in /etc/cloud/templates/hosts.redhat.tmpl
# b.) change or remove the value of 'manage_etc_hosts' in
# /etc/cloud/cloud.cfg or cloud-config from user-data
#
# The following lines are desirable for IPv4 capable hosts
127.0.0.1 lenaic-node-compute-cf3fb.example.com lenaic-node-compute-cf3fb
127.0.0.1 localhost.localdomain localhost
127.0.0.1 localhost4.localdomain4 localhost4
# The following lines are desirable for IPv6 capable hosts
::1 lenaic-node-compute-cf3fb.example.com lenaic-node-compute-cf3fb
::1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
```
Disabling `manage_etc_hosts` removes the lines for `lenaic-node-compute-cf3fb` from `/etc/hosts`
and makes than name resolved by the DNS to its real IP.

Use write_files to disable requiretty for the openshift user as suggested by @detiberm, fixes #773
|
| |
|
| |
Set Defaults !requiretty so that ansible can run sudo without a terminal. Fixes #773

Using bootcmd in cloud-config lead to restarts prior to starting the
systemd-hostnamed, which was probable cause of the failure when DHCP
client was failing to send the hostname, and subsequently, the
ansible-opnshift was not able to identify the VM among the others when
checking DHCP leases. The failure looked like: following
10:17:31 failed: [localhost] => {"attempts": 60, "changed": true, "cmd": "virsh -c qemu:///system net-dhcp-leases openshift-ansible | egrep -c 'experiment-node-compute-453d0|experiment-node-compute-61e16'", "delta": "0:00:00.033061", "end": "2015-10-19 10:17:31.409434", "failed": true, "rc": 0, "start": "2015-10-19 10:17:31.376373", "warnings": []}
10:17:31 stdout: 1

The dnsmasq should not be resolving the example.com recursively, because
in case that we have /etc/NetworkManager/dnsmasq.d/libvirt_dnsmasq.conf:
server=/example.com/192.168.55.1
the dnsmasq will be asking itself, therefore a dns resolution loop is
created, which causes
Maximum number of concurrent DNS queries reached (max: 150)
and performance degradation of dns resolution on the whole hypervizor and
guests.
This patch will fix that in the domain.xml, which will cause adding
local=/example.com/
to the /var/lib/libvirt/dnsmasq/openshift-ansible.conf, effectively
fixing the problem.

According to https://libvirt.org/formatdomain.html#elementsMetadata , the `metadata` tag can contain only one top-level element per namespace.
Because of that, libvirt stored only the `deployment-type-{{ deployment_type }}` tag.
As a consequence, the dynamic inventory reported no `env-{{ cluster }}` group.
This is problematic for the `terminate.yml` playbook which iterates over `groups['tag-env-{{ cluster-id }}]`
The symptom is that `oo_hosts_to_terminate` was not defined.
In the end, as Ansible couldn’t iterate on the value of `groups['oo_hosts_to_terminate']`, it iterated on its letters:
```
