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 0000:00:19.0> /sys/bus/pci/drivers/e1000e/unbind $> echo -n 0000:00:19.0> /sys/bus/pci/drivers/pci-stub/bind 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?
