...======= NPIV in libvirt NPIV (N_Port ID Virtualization) is a Fibre Channel technology to share a single physical Fibre Channel HBA with multiple virtual ports. Henceforth known as a "virtual port" or "virtual Host Bus Adapter" (vHBA), each virtual port is identified by its own WWPN (Word Wide Port Name) and WWNN (Word Wide Node Name). In the virtualization world the vHBA controls the LUNs for virtual machines. The libvirt implementation provides flexibility to configure the LUN's either directly to the virtual machine or as part of a storage pool which then can be config...

How it this supposed to work? You do export the WWPN/WWNN of the associated host to the guest (nb: will get interesting for non NPIV setups ...), but virtio scsi will still do a LUN remapping. IE the LUNs you see on the host will be different from the LUNs presented to the guest. This makes reliable operations very tricky. Plus you don't _actual...

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:
