I just looked at my Xen hg tree checkout, and I see that Xen builds IB
drivers for its kernel too. Does the Ubuntu Xen kernel really turn
off the IB modules?
Hmm, no it does include them. I just checked:
$ dpkg -L xen-image-xen0-2.6.16-11.2-generic|grep infiniband
/lib/modules/2.6.16-11.2-generic/kernel/drivers/infiniband
/lib/modules/2.6.16-11.2-generic/kernel/drivers/infiniband/core
/lib/modules/2.6.16-11.2-generic/kernel/drivers/infiniband/core/ib_cm.ko

/lib/modules/2.6.16-11.2-generic/kernel/drivers/infiniband/ulp/srp
/lib/modules/2.6.16-11.2-generic/kernel/drivers/infiniband/ulp/srp/ib_srp.ko
So I would recommend just using what Ubuntu packaged for you, no need
to mess around with the OFED kernel module build.
BTW, any reason not to use Ubuntu's 2.6.17 Xen kernel? I honestly
don't know much about Ubuntu's Xen support so maybe the 2.6.16 kernel
really is better.
