Multi-Hypervisor Scenario (LXD + KVM)
=====================================
An OpenStack-on-OpenStack example exercise.
### Get o-c-t bundle and scripts
```
mkdir -p ~/tools
bzr branch lp:openstack-charm-testing ~/tools/openstack-charm-testing
cd ~/./tools/openstack-charm-testing
```
### Deploy
Bootstrap, then deploy Wily + Liberty.
```
juju-deployer -vdB -c bundles/multi-hypervisor/default.yaml xenial-mitaka
```
### Configure
Add images, add 2nd NIC to neutron-gateway instance, create tenant, tenant router, networks.
```
./configure multihypervisor
```
### Source the deployed overcloud nova credentials
```
. ~/tools/openstack-charm-testing/novarc
```
### Inspect and confirm the deployed cloud
```

```
### Shrink flavors
Not required, but useful when testing density.
```
./tools/flavor_shrink.sh
```
### Set quotas really high
Not required, but allows drastic resource overcommits.
```
./tools/quota_million.sh
```
### Set security groups + MTU
Very permissive secgroups for testing, and lower instance MTU due to nested tunnels in cloud-on-cloud scenarios.
```
./tools/sec_groups.sh
```
### Create 3 new trusty (kvm) instances
```
./tools/instance_launch.sh 3 trusty-disk1.img
```
### Create 3 new trusty (lxd) instances
```
./tools/instance_launch.sh 3 trusty-root.tar.xz
```
### Watch the instances go ACTIVE
```
