Here are the exact steps I used:
1. lspci -n on host:
06:00.0 0c06: 15b3:634a (rev a0)
I want to assign this device to guest.
2. Uninstall driver for this device.
3. Unbind device with the following commands:
echo 15b3 634a /sys/bus/pci/drivers/pci-stub/new_id
echo :06:00.0 /sys/bus/pci/devices/:06:00.0/driver/unbind
echo :06:00.0 /sys/bus/pci/drivers/pci-stub/bind
4. start guest with... -pcidevice host=06:00.0
5. Guest os detects device with lspci command but failed to start.
lspci -tv on host:(last device here is what i want to assign)

Anyone has experience to assign PCI-E based InfiniBand card to
guest OS(RHEL5U2 with kernel 2.6.18-92) on latest AMD with IOMMU
support. Host OS has kernel 2.6.29.
Steps I used:
$ echo -n 8086 10de /sys/bus/pci/drivers/pci-stub/new_id
$ echo -n :00:19.0 /sys/bus/pci/drivers/e1000e/unbind
$ echo -n :00:19.0 /sys/bus/pci/drivers/pci-stub/bind
The steps above are specific to an e1000e device.
Then
I started guest with -pcidevice host=id. After guest is started, it
successfully detected pci device with lspci command, however kernel
can't bring up the device. dmesg shows infiniband kernel module can't
detect infiniband card firmware properly then aborted. I think it is
KVM issue rather than infiniband kernel module issue. Can anyone
suggest?
Sounds like you may have two drivers for this device.
Can you include (on the host) lspci -tv and lspci -vvv?
thanks,
