Should correct issues on cold start as well as if a VM crashes uncleanly, which would prevent the VM from starting due to stale RBD locks. This implementation has four parts: 1. Update how IP addresses are handled, specifically by replacing all previous instances of "vni_ipaddr" with "vni_floatingipaddr", and then adding the "vni_ipaddr" with the real data for this node's IPs. Also include the storage IPs in this where they weren't before, so each this_node actually has the local IPs plus floating IPs. This enables the next two steps. 2. Modify flush_locks to take this_node as an argument, and update the run_command function to only operate against this node, rather than on the primary coordinator. 3. Have the flush_locks check each lock against the current node, to verify that the lock is actually held by the current node. This is the only way to do this safely. During fencing, we override this by not passing a this_node which bypasses this check. 4. Have the VM start do the check for VM failure/startup and execute a flush_locks before actually starting the VM. |

PVC - The Parallel Virtual Cluster system
NOTICE FOR GITHUB: This repository is a read-only mirror of the PVC repositories from my personal GitLab instance. Pull requests submitted here will not be merged. Issues submitted here will however be treated as authoritative.
PVC is a KVM+Ceph+Zookeeper-based, Free Software, scalable, redundant, self-healing, and self-managing private cloud solution designed with administrator simplicity in mind. It is built from the ground-up to be redundant at the host layer, allowing the cluster to gracefully handle the loss of nodes or their components, both due to hardware failure or due to maintenance. It is able to scale from a minimum of 3 nodes up to 12 or more nodes, while retaining performance and flexibility, allowing the administrator to build a small cluster today and grow it as needed.
The major goal of PVC is to be administrator friendly, providing the power of Enterprise-grade private clouds like OpenStack, Nutanix, and VMWare to homelabbers, SMBs, and small ISPs, without the cost or complexity. It believes in picking the best tool for a job and abstracting it behind the cluster as a whole, freeing the administrator from the boring and time-consuming task of selecting the best component, and letting them get on with the things that really matter. Administration can be done from a simple CLI or via a RESTful API capable of building full-featured web frontends or additional applications, taking a self-documenting approach to keep the administrator learning curvet as low as possible. Setup is easy and straightforward with an ISO-based node installer and Ansible role framework designed to get a cluster up and running as quickly as possible. Build your cloud in an hour, grow it as you need, and never worry about it: just add physical servers.
Getting Started
To get started with PVC, please see the About page for general information about the project, and the Getting Started page for details on configuring your cluster.

v0.9.1
- Added per-VM migration method feature
- Fixed bug with provisioner system template listing
v0.9.0
Numerous small improvements and bugfixes. This release is suitable for general use and is pre-release-quality software.
This release introduces an updated version scheme; all future stable releases until 1.0.0 is ready will be made under this 0.9.z naming. This does not represent semantic versioning and all changes (feature, improvement, or bugfix) will be considered for inclusion in this release train.
v0.8
Numerous improvements and bugfixes. This release is suitable for general use and is pre-release-quality software.
v0.7
Numerous improvements and bugfixes, revamped documentation. This release is suitable for general use and is beta-quality software.
v0.6
Numerous improvements and bugfixes, full implementation of the provisioner, full implementation of the API CLI client (versus direct CLI client). This release is suitable for general use and is beta-quality software.
v0.5
First public release; fully implements the VM, network, and storage managers, the HTTP API, and the pvc-ansible framework for deploying and bootstrapping a cluster. This release is suitable for general use, though it is still alpha-quality software and should be expected to change significantly until 1.0 is released.
v0.4
Full implementation of virtual management and virtual networking functionality. Partial implementation of storage functionality.
v0.3
Basic implementation of virtual management functionality.
