after using PCI-PASSTHROUG FC-HBA is visible in the domU.
1.
-----------
domU output:
root@guest03:~# lspci
01:05.0 Fibre Channel: QLogic Corp. ISP2312-based 2Gb Fibre Channel to
PCI-X HBA (rev 02)
2.
------
root@guest03:~# cat /proc/scsi/scsi
Attached devices:
proc/scsi does not show any output.
3. Dmesg for qlogic while booting domU.

4.
--------
/sys/class/fc_host shows nothing
root@guest03:/sys/class# ls -l /sys/class/fc_host/
total 0
root@guest03:/sys/class#
Now how do i access these scsi device in domU using pci passthrough.
Any pointers will be approciated.
thanks
