Implements a locking mechanism to prevent clobbering of node flushes. When a flush begins, a global cluster lock is placed which is freed once the flush completes. While the lock is in place, other flush events queue waiting for the lock to free before proceeding. Modifies the CLI output flow when the `--wait` option is specified. First, if a lock exists when running the command, the message is tweaked to indicate this, and the client will wait first for the lock to free, and then for the flush as normal. Second, the wait depends on the active lock rather than the domain_status for consistency purposes. Closes #32
PVC - The Parallel Virtual Cluster suite
PVC is a suite of Python 3 tools to manage virtualized clusters. It provides a fully-functional private cloud based on four key principles:
- Be Free Software Forever (or Bust)
- Be Opinionated and Efficient and Pick The Best Software
- Be Scalable and Redundant but Not Hyperscale
- Be Simple To Use, Configure, and Maintain
It is designed to be an administrator-friendly but extremely powerful and rich modern private cloud system, but without the feature bloat and complexity of tools like OpenStack. With PVC, an administrator can provision, manage, and update a cluster of dozens or more hypervisors running thousands of VMs using a simple CLI tool, HTTP API, or web interface. PVC is based entirely on Debian GNU/Linux and Free-and-Open-Source tools, providing the glue to bootstrap, provision and manage the cluster, then getting out of the administrators' way.
Your cloud, the best way; just add physical servers.
