Add the 'iothreadsinfo' command to display IOThread Info data. Allow for [--live] or [--config] options in order to display live or config data for an active domain.
$ virsh iothreadsinfo --help NAME iothreadsinfo - view domain IOThreads
SYNOPSIS iothreadsinfo <domain> [--config] [--live] [--current]
DESCRIPTION Returns basic information about the domain IOThreads.
OPTIONS [--domain] <string> domain name, id or uuid --config affect next boot --live affect running domain --current affect current domain
An active domain may return:
$ virsh iothreads $dom IOThread ID CPU Affinity --------------------------------------------------- 1 2 2 3 3 0
$ echo $? 0
For domains which don't have IOThreads the following is returned:
$ virsh iothreads $dom No IOThreads found for the domain
$ echo $? 0
For domains which are not running the following is returned:
$ virsh iothreads $dom --live error: Unable to get domain IOThreads information error: Requested operation is not valid: domain is not running
$ echo $? 1
Editing a domains configuration and modifying the iothreadpin data for thread 3 from nothing provided to setting a cpuset of '0-1' and then displaying using --config would display:
$ virsh iothreads f18iothr --config IOThread ID CPU Affinity ---------------------------- 1 2 2 3 3 0-1
