-LIBVIRT Setup instructions
-==========================
-
-`libvirt` is an `openshift-ansible` provider that uses `libvirt` to create local Fedora VMs that are provisioned exactly the same way that cloud VMs would be provisioned.
-
-This makes `libvirt` useful to develop, test and debug OpenShift and openshift-ansible locally on the developer’s workstation before going to the cloud.
-
-Install dependencies
---------------------
-
-1. Install [ansible](http://www.ansible.com/)
-2. Install [dnsmasq](http://www.thekelleys.org.uk/dnsmasq/doc.html)
-3. Install [ebtables](http://ebtables.netfilter.org/)
-4. Install [qemu and qemu-system-x86](http://wiki.qemu.org/Main_Page)
-5. Install [libvirt-python and libvirt](http://libvirt.org/)
-6. Install [genisoimage](http://cdrkit.org/)
-7. Enable and start the libvirt daemon, e.g:
- - `systemctl enable libvirtd`
- - `systemctl start libvirtd`
-8. [Grant libvirt access to your user¹](https://libvirt.org/aclpolkit.html)
-9. Check that your `$HOME` is accessible to the qemu user²
-10. Configure dns resolution on the host³
-11. Install libselinux-python
-
-#### ¹ Depending on your distribution, libvirt access may be denied by default or may require a password at each access.
-
-You can test it with the following command:
-
-```
-virsh -c qemu:///system pool-list
-```
-
-If you have access error messages, please read https://libvirt.org/acl.html and https://libvirt.org/aclpolkit.html .
-
-In short, if your libvirt has been compiled with Polkit support (ex: Arch, Fedora 21), you can create `/etc/polkit-1/rules.d/50-org.libvirt.unix.manage.rules` as follows to grant full access to libvirt to `$USER`
-
-```
-sudo /bin/sh -c "cat - > /etc/polkit-1/rules.d/50-org.libvirt.unix.manage.rules" << EOF
-polkit.addRule(function(action, subject) {
- if (action.id == "org.libvirt.unix.manage" &&
- subject.user == "$USER") {
- return polkit.Result.YES;
- polkit.log("action=" + action);
- polkit.log("subject=" + subject);
- }
-});
-EOF
-```
-
-If your libvirt has not been compiled with Polkit (ex: Ubuntu 14.04.1 LTS), check the permissions on the libvirt unix socket:
-
-```
-ls -l /var/run/libvirt/libvirt-sock
-srwxrwx--- 1 root libvirtd 0 févr. 12 16:03 /var/run/libvirt/libvirt-sock
-
-usermod -a -G libvirtd $USER
-# $USER needs to logout/login to have the new group be taken into account
-```
-
-(Replace `$USER` with your login name)
-
-#### ² Qemu will run with a specific user. It must have access to the VMs drives
-
-All the disk drive resources needed by the VMs (Fedora disk image, cloud-init files) are put inside `~/libvirt-storage-pool-openshift/`.
-
-As we’re using the `qemu:///system` instance of libvirt, qemu will run with a specific `user:group` distinct from your user. It is configured in `/etc/libvirt/qemu.conf`. That qemu user must have access to that libvirt storage pool.
-
-If your `$HOME` is world readable, everything is fine. If your `$HOME` is private, `ansible` will fail with an error message like:
-
-```
-error: Cannot access storage file '$HOME/libvirt-storage-pool-openshift/lenaic-master-216d8.qcow2' (as uid:99, gid:78): Permission denied
-```
-
-In order to fix that issue, you have several possibilities:
- * set `libvirt_storage_pool_path` inside `playbooks/libvirt/openshift-cluster/launch.yml` and `playbooks/libvirt/openshift-cluster/terminate.yml` to a directory:
- * backed by a filesystem with a lot of free disk space
- * writable by your user;
- * accessible by the qemu user.
- * Grant the qemu user access to the storage pool.
-
-On Arch or Fedora 22+:
-
-```
-setfacl -m g:kvm:--x ~
-```
-
-#### ³ Enabling DNS resolution to your guest VMs with NetworkManager
-
-- Verify NetworkManager is configured to use dnsmasq:
-
-```sh
-$ sudo vi /etc/NetworkManager/NetworkManager.conf
-[main]
-dns=dnsmasq
-```
-
-- Configure dnsmasq to use the Virtual Network router for example.com:
-
-```sh
-sudo vi /etc/NetworkManager/dnsmasq.d/libvirt_dnsmasq.conf
-server=/example.com/192.168.55.1
-```
-
-Test The Setup
---------------
-
-1. cd openshift-ansible/
-2. Try to list all instances (Passing an empty string as the cluster_id argument will result in all libvirt instances being listed)
-
-```
- bin/cluster list libvirt ''
-```
-
-Configuration
--------------
-
-The following options can be passed via the `-o` flag of the `create` command or as environment variables:
-
-* `image_url` (default to `http://cloud.centos.org/centos/7/images/CentOS-7-x86_64-GenericCloud.qcow2.xz`): URL of the QCOW2 image to download
-* `image_name` (default to `CentOS-7-x86_64-GenericCloud.qcow2`): Name of the QCOW2 image to boot the VMs on
-* `image_compression` (default to `xz`): Source QCOW2 compression (only xz supported at this time)
-* `image_sha256` (default to `dd0f5e610e7c5ffacaca35ed7a78a19142a588f4543da77b61c1fb0d74400471`): Expected SHA256 checksum of the downloaded image
-* `libvirt_storage_pool` (default to `openshift-ansible`): name of the libvirt storage pool for the VM images. It will be created if it does not exist
-* `libvirt_storage_pool_path` (default to `$HOME/libvirt-storage-pool-openshift-ansible`): path to `libvirt_storage_pool`, i.e. where the VM images are stored
-* `libvirt_network` (default to `openshift-ansible`): name of the libvirt network that the VMs will use. It will be created if it does not exist
-* `libvirt_instance_memory_mib` (default to `1024`): memory of the VMs in MiB
-* `libvirt_instance_vcpu` (default to `2`): number of vCPUs of the VMs
-* `skip_image_download` (default to `no`): Skip QCOW2 image download. This requires the `image_name` QCOW2 image to be already present in `$HOME/libvirt-storage-pool-openshift-ansible`
