Since xen version 4.5.1 there is a bug with the xl cpupool-create command.
It always throws a segmentation fault when used with a config file as
parameter.
The content of the config file does not really matter (valid or invalid).
It also fails with the example config file in /etc/xen/cpupool or with
the dryrun flag.
You never get any output apart from "segmentation fault".
If you create exactly the same cpupool without using a config file it
works absolutely fine.
Tested on multiple systems and it seems to be reproducible for everyone.
STrace shows that the command fails right after reading the content of
the config file.
