# OpenStack
|
|
|
|
|
|
|
|
|
|
To enable Vitastor support in an OpenStack installation:
|
|
|
|
|
|
|
|
|
|
- Install vitastor-client, patched QEMU and libvirt packages from Vitastor DEB or RPM repository
|
|
|
|
|
- Use `patches/nova-21.diff` or `patches/nova-23.diff` to patch your Nova installation.
|
|
|
|
|
Patch 21 fits Nova 21-22, patch 23 fits Nova 23-24.
|
|
|
|
|
- Install `patches/cinder-vitastor.py` as `..../cinder/volume/drivers/vitastor.py`
|
|
|
|
|
- Define a volume type in cinder.conf (see below)
|
|
|
|
|
- Block network access from VMs to Vitastor network (to OSDs and etcd),
|
|
|
|
|
because Vitastor doesn't support authentication
|
|
|
|
|
- Restart Cinder and Nova
|
|
|
|
|
|
|
|
|
|
Cinder volume type configuration example:

To put Glance images in Vitastor, use [volume-backed images](https://docs.openstack.org/cinder/pike/admin/blockstorage-volume-backed-image.html),

although the support has not been verified yet.
