When create a virtual FC HBA with virsh/libvirt API, an error message will be
returned:"error: Node device not found",
also the 'nodedev-dumpxml' shows wrong information of wwpn & wwnn for the new
created device.

Hmm, this is what we've had before commit f90af69 [1]
but according to scsi_fc_transport.txt [2] in kernel docs, it should be
<WWPN>:<WWNN>. I wonder what that commit was trying to fix.

Interesting! According to my testing result (kernel version 2.6.32), 
kernel docs is correct,it should be <WWPN>:<WWNN>. It's causing me 
trouble when creating the device with virsh after that commit...

BRs,
