As per my comment on SPDK issue, I don't think this is vfio-user related at all.

NVMF_VFIO_USER_DOORBELLS_SIZE should be 4K in your case, that's why it breaks, and as John said this is not a libvfio-user issue.
How to resolve this issue?
You need to align NVMF_VFIO_USER_DOORBELLS_SIZE to the system page size (currently we assume 4K) and possibly adapt relevant code. I bet this isn't the only place where we assume a 4K page size in nvmf/vfio-user.
Does libvfio-user support 64K pages?
I believe it does.

As this isn't a libvfio-user issue, I'm closing this.
@peng6662001 please feel free to open further issues as and when you discover issues with the library (or the protocol!). Thanks.
