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 $ Signed-off-by: John Ferlan <jferlan@redhat.com>
LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed. Daniel Veillard <veillard@redhat.com>
Description
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
