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
