Joshua Boniface b17b7bf22b Add black magic to minimize ping losses 
This particular arping interval/count, along with forcing it to run in
the foreground, seems to minimize the packet loss when the primary
coordinator transitions. Through extensive testing, this value results
in the, consistently, least amount of loss: 1-2 pings, at an 0.025s ping
interval, return "TTL exceeded", with no other loss, and only when the
node the test VM is on is the one switching to secondary state. No other
combination of values here, nor tweaks to other parts of the code, seem
able to reduce this further, therefore this is likely the best
configuration possible.

PVC - The Parallel Virtual Cluster suite

Logo banner

License Release Pipeline Status Documentation Status

PVC is a suite of Python 3 tools to manage virtualized clusters. It provides a fully-functional private cloud based on four key principles:

  1. Be Free Software Forever (or Bust)
  2. Be Opinionated and Efficient and Pick The Best Software
  3. Be Scalable and Redundant but Not Hyperscale
  4. 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 [eventually] 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.
