I am curious. Aren't RoCE adapters just PCIe devices? If things are set
up correctly and drivers are present, I don't think Xen has any problem
supporting them.

Do you have any reference that Oracle migrates to KVM *because* Xen
cannot support RoCE? Or is it simply that Oracle is migrating to KVM in
general?

I haven't worked on RoCE before so I could be wrong.
