Question about vport operation for FC HBA
...rsh # 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't find any FC host with:
#virsh nodedev-list --cap fc_host
SCSI hosts can be found for above "nodedev-list --cap scsi_host&quo...

I was suspicious about it because they are defined as "u8 x[8]" in the
virtio_scsi_config struct. So you would need...

I think so. The fc_host sysfs uses u64 to represent port_name and node_name,
this patch does the same, so using virtio_* helpers for these fields should
handle the endianness correctly.
Maybe we should use u64 in struct virtio_scsi_config as well?

[PATCH 2/2] virtio_scsi: Implement fc_host
This implements the VIRTIO_SCSI_F_FC_HOST feature by reading the config
fields and presenting them as sysfs fc_host attributes. The config
change handler is added here because primary_active will toggle during
migration.
