no luck !
dmesg in XEN PV guest shows :
ib_mthca: Mellanox InfiniBand HCA driver v1.0 (April 4, 2008)
ib_mthca: Initializing 0000:00:00.0
PCI: Enabling device 0000:00:00.0 (0000 -> 0002)
PCI: Setting latency timer of device 0000:00:00.0 to 64
ib_mthca 0000:00:00.0: QUERY_FW command failed, aborting.
ib_mthca: probe of 0000:00:00.0 failed with error -11
even after executingh the following in dom0:
#echo -n 0000:0e:00.0 > /sys/bus/pci/drivers/pciback/permissive
I am getting the follwing messages on the console as part of the initial bootup messages of the guest:
Started domain rhel52_64_3
PCI: Fatal: No PCI config space access function found
rtc: IRQ 8 is not free.
i8042.c: No controller found.
after executing the following in dom0 :
#xm create -c rhel52_64_3
so, problem persisits,

Seems it is because PCI frontend try to write some configuration space that PCIback has no config_field entry to support it.
I think you can firstly try to do as dom0's dmesg suggested: "see permissive attribute in sysfs" (it should be "set permissive attribute...", I think).
BTW, where you got following log? That seems suggest config space function not found.
PCI: Fatal: No PCI config space access function found
rtc: IRQ 8 is not free.
i8042.c: No controller found."

I am getting the same QUERY_FW failed on RHEL5.2 with xenxen paravirtualized guest with pciback module.
No one seems to have tried answering this question on the list, let me ping xen-devel and ofed people again.
after executing in dom0

Okay so my question to the openfabrics guys is, why would the OFED
drivers fail to read the firmware?
Any thoughts?

This issue was brought up about a year and a half ago. So I'll bring
it up again and see if anything happens.
I've got an infiniband network and am attempting to pass the
infiniband card through the host and give it to the guest.
I'm working with standard CentOS 5.2 on both guest and host with their
provided xen (3.0.3 ish). I've also attempted to install the newest
Xen 3.3 and use their standard host kernel and that did the same
thing. The guest dmesg output in the guest is similar on both
permissive and normal mode.
I'm getting issues with detecting the firmware on the card for some reason...
Any help would be appreciated.
Thanks,
- David Brown
