Hi, When I want to use NPIV for a FC HBA in my Linux machine, I got the below error msg in virsh: virsh # nodedev-create /home/kvm/vHBA.xml error: Failed to create node device from /home/kvm/vHBA.xml error: internal error Parent device scsi_host20 is not capable of vport operations I checked the /sys/class folder for my HBA device that I want to use its NPIV feature, it's there: /sys/class/fc_host/host20/vport_create I can create a vHBA by using "echo 'xxxx:xxxx' > ./vport_create", a new fc host will be created after that. But I can...

...cribe NPIV functionality as of the current libvirt release, 1.1.2. There will be a troubleshooting and prior version considerations section to describe some historical differences. 1) Discovery Discovery of HBA(s) capable of NPIV is provided through the virsh command 'virsh nodedev-list --cap vports'. If no HBA is returned, then the host configuration should be checked. The XML output from the command "virsh nodedev-dumpxml" will list fields <name>, <wwnn>, and <wwpn> to be used in order to create a vHBA. Take care to also note the <max_vports> value as t...

...The document tries to summary up the things about NPIV that libvirt supports till now, and the TODO list. Feedback or suggestion is welcomed. 1) How to find out which HBA(s) support vHBA For libvirt newer than "1.0.4", you can find it out simply by: # virsh nodedev-list --cap vports "--cap vports" is to tell "nodedev-list" only outputs the devices which support "vports" capability, i.e. support vHBA. And also since version "1.0.4", you should be able to know the maximum vports the HBA supports and the current vports number from...
