[ofa-general] Loading ib_gmthca module into guest domain

[Adit Ranadive]

Hi,

I was partly succesful in inserting the ib_gmthca module into the guest domain.
This is the debug output I get while inserting the module :

modprobe ib_gmthca mc=1 domain=2
host ip 192.168.0.3
domain 2
[drivers/infiniband/hw/gmthca/../../utils/kernel_socket.c:62],<1>Connection ok

QP 65536, MAX CQ 65536, max sge 59
fail to recv ret value (ret 0) or ret value error (24 but receive -16)
Fail to execute command

It is able to get the device limits (gmthca_get_limits function) but
it fails after that.
I was unable to debug where exactly it was failing.

Before loading the module in guest domain I load the kibad, ib_mthca
modules in dom0.

Any steps I have missed in order to correctly load the module in guest?
Any pointers here will be helpful.

Thanks,
Adit
