The fact that it is possible to do that doesn't imply that it is the best solution. Oh, and btw: What was the reason why kvm paravirtualization doesn't use the vmi interface? >>> the QA matrix is gonna be a _mess_. >> I fail to see how xen-via-vmirom instead of xen-via-paravirt_ops >> reduces the QA effort.

I doubt moving the abstraction line within the linux kernel from paravirt_ops to vmi makes QA easier. cheers, Gerd -- Gerd Hoffmann <kraxel at suse.de>
