Looks good, in the future we may want to switch the default to false once testing has shown that it is not needed anymore.
I think that the protection we have in Dom0 (with control-slice) against qemu taking away CPU from XAPI should be sufficient these days, but some pool bootstorm tests should give us some data on this.

info.citrite.net is not a URL that is publicly accessible so it is best to avoid posting internal URLs like that in commit messages or PRs. |

If it is just the 2 screenshots from XenCenter (which is open source) then you can add them directly here, there is now a github feature 'attach files by dragging&dropping,selecting or pasting them' at the bottom of thse comment boxes. Not sure whether it works with images though. |

coordinator_bias on (default): coordinator_bias off: |
By design, the pool master has a bias against scheduling VMs on it, preferring other member hosts.
An option to toggle this bias has been added, which can be used to improve performance, for example when the non-master hosts get overloaded.
