virsh: Add iothreadadd and iothreaddel commands
https://bugzilla.redhat.com/show_bug.cgi?id=1161617 Add command to allow adding and removing IOThreads from the domain including the configuration and live domain. $ virsh iothreadadd --help NAME iothreadadd - add an IOThread to the guest domain SYNOPSIS iothreadadd <domain> <id> [--config] [--live] [--current] DESCRIPTION Add an IOThread to the guest domain. OPTIONS [--domain] <string> domain name, id or uuid [--id] <number> iothread for the new IOThread --config affect next boot --live affect running domain --current affect current domain $ virsh iothreaddel --help NAME iothreaddel - delete an IOThread from the guest domain SYNOPSIS iothreaddel <domain> <id> [--config] [--live] [--current] DESCRIPTION Delete an IOThread from the guest domain. OPTIONS [--domain] <string> domain name, id or uuid [--id] <number> iothread_id for the IOThread to delete --config affect next boot --live affect running domain --current affect current domain Assuming a running $dom with multiple IOThreads assigned and that that the $dom has disks assigned to IOThread 1 and IOThread 2: $ virsh iothreadinfo $dom IOThread ID CPU Affinity --------------------------------------------------- 1 2 2 3 3 0-1 $ virsh iothreadadd $dom 1 error: invalid argument: an IOThread is already using iothread_id '1' in iothreadpids $ virsh iothreadadd $dom 1 --config error: invalid argument: an IOThread is already using iothread_id '1' in persistent iothreadids $ virsh iothreadadd $dom 4 $ virsh iothreadinfo $dom IOThread ID CPU Affinity --------------------------------------------------- 1 2 2 3 3 0-1 4 0-3 $ virsh iothreadinfo $dom --config IOThread ID CPU Affinity --------------------------------------------------- 1 2 2 3 3 0-1 $ virsh iothreadadd $dom 4 --config $ virsh iothreadinfo $dom --config IOThread ID CPU Affinity --------------------------------------------------- 1 2 2 3 3 0-1 4 0-3 Assuming the same original configuration $ virsh iothreaddel $dom 1 error: invalid argument: cannot remove IOThread 1 since it is being used by disk 'vde' $ virsh iothreaddel $dom 3 $ virsh iothreadinfo $dom IOThread ID CPU Affinity --------------------------------------------------- 1 2 2 3 $ virsh iothreadinfo $dom --config IOThread ID CPU Affinity --------------------------------------------------- 1 2 2 3 3 0-1
