[Xen-devel] Dedicate PCI Devices to DomU?

I am trying to dedicate a number of  PCI ports to DomU and no success!

 

The PCI devices I am trying to dedicate are QLogic 23xx cards!

 

I am using SUSE 10.1 with latest xen-unstable!

 

I have followed all the instructions given in latest xen 3.0 manual.

 

Like building the backend support in Dom0

Building the frontend support in DomU

Using the pciback.hide=(xx:xx.x) in Dom0 command line (and it
successfully hides the devices!)

 

Later while I try to load the driver in Dom1 it doesn''t load and seems
to miss some of pci libraries..I am guessing this is due to stripped
down version of DomU build by xen-unstable. This is what it throws!



qla2xxx: Unknown symbol fc_attach_transport

qla2xxx: Unknown symbol pci_set_consistent_dma_mask

qla2xxx: Unknown symbol pci_enable_device

qla2xxx: Unknown symbol fc_remote_port_add

qla2xxx: Unknown symbol fc_remove_host

qla2xxx: Unknown symbol pci_request_regions

qla2xxx: Unknown symbol pci_bus_write_config_byte

qla2xxx: Unknown symbol fc_remote_port_delete

qla2xxx: Unknown symbol pci_bus_read_config_dword

qla2xxx: Unknown symbol pci_bus_read_config_word

qla2xxx: Unknown symbol fc_release_transport

qla2xxx: Unknown symbol pci_set_mwi

qla2xxx: Unknown symbol pci_find_capability

qla2xxx: Unknown symbol fc_remote_port_rolechg

qla2xxx: Unknown symbol pci_bus_write_config_dword

qla2xxx: Unknown symbol pci_set_master

qla2xxx: Unknown symbol pci_bus_write_config_word

qla2xxx: Unknown symbol pci_release_regions

qla2xxx: Unknown symbol scsi_is_fc_rport

qla2xxx: Unknown symbol pci_disable_device

 

I have attached the logs of Dom1 and Dom0. Can anyone please tell me if
anything is missing?

 

Note: with xen 2.0 I was able to load at least partially the Qlogic
driver on Dom1. It used to crash after a while!

 

Thanks,

Rafiq

This looks to me like you setup everything to be a module and didn''t
copy them over to your domU.  Can you send your domU .config to confirm
this?
