This commit introduces "check-xl-vcpupin-parse" for helping
verifying and debugging the (v)CPU bitmap parsing code in xl.
The script runs "xl -N vcpu-pin 0 all <some strings>"
repeatedly, with various input strings, and checks that the
output is as expected.
This is what the script can do:
# ./check-xl-vcpupin-parse -h
usage: ./check-xl-vcpupin-parse [options]
Tests various vcpu-pinning strings. If run without arguments acts
as follows:
- generates some test data and saves them in
check-xl-vcpupin-parse.data;
- tests all the generated configurations (reading them back from
check-xl-vcpupin-parse.data).
An example of a test vector file is provided in
check-xl-vcpupin-parse.data-example.
Options:
-h prints this message
-r seed uses seed for initializing the rundom number generator
(default: the script PID)
-s string tries using string as a vcpu pinning configuration and
reports whether that succeeds or not
-o ofile save the test data in ofile
(default: check-xl-vcpupin-parse.data)
-i ifile read test data from ifile
An example test data file (generated on a 2 NUMA nodes, 16 CPUs
host) is being provided in check-xl-vcpupin-parse.data-example.
