Hi,
I have a project which is make KVM use InfiniBand.
However, since Xen can use InfiniBand through Xen-IB, I want to try to make Xen use InfiniBand first.
Through that way, I think it may give me some idea about how to make KVM use InfiniBand.
So, as you said, I just use "Updated defconfig to include infiniband driver as modules for dom0/domU" to do?
And since I don't know how to I do first for Xen-IB, is there any tutorial for Xen-IB?
Or does Xen build-in support IB currently?
Yi-Man

maintained since -- I am very sceptical that you will find anything of
use on a modern Xen system in there.
I expect that IB support in the kernels we currently use for dom0 is
vastly improved over what was available in the 2.6.16 tree referenced in
the above repository. Perhaps you don't even need anything special
outside of what is available in the upstream dom0 kernel.
Perhaps if you explain what you are actually trying to achieve then
people will be able to better advise you?
Ian.
