[Xen-devel] [PATCH 0/9] Some (not only) cpupool related fixes and improvements

[Dario Faggioli <dario.faggioli@xxxxxxxxxx>]

Hi everyone,

The main goal of this series is making it possible to specify ranges of pCPUs
when manipulating (creating, adding/removing pCPUs) cpupools. Something like
this:

 xl cpupool-cpu-remove Pool-node0 6-10

while, right now, only single pCPU IDs can be specified, which means that, to
achieve the above, we need to do this:

 xl cpupool-cpu-remove Pool-node0 6
 xl cpupool-cpu-remove Pool-node0 7
 xl cpupool-cpu-remove Pool-node0 8
 xl cpupool-cpu-remove Pool-node0 9
 xl cpupool-cpu-remove Pool-node0 10

This is done in patches 5/9, 6/9 and 7/9.

The series also add a new parameter to `xl list', '-c' or '--cpupool', which
shows in which cpupool the domain(s) lives. Such information was not easy to
find in any other way. One can use `xl sched-<schedule_of_cpupool_x>' and have,
as a side effect, something similar, but that's rather impractical.

Sample output for the new `xl list' can be found here:

This happens in patch 3/9 and 4/9.

While there, the series includes some other, somewhat related, fixes of various
kind.

This is available as a git branch here:

Thanks and Regards,
Dario
