Hello all,
I have just started working with KVM and
virtualization in general. I have setup a client using Suse 9.3 x64
as the base and Fedora 15 x64 as the host. The kernel in the client
has been upgraded to a custom 2.6.28.4 build.
Everything seems
to be working fine but I wanted to get som

Actually there's an additional complication: PAGE_SIZE is entrenched in
the layout of the ring structure itself (large "struct vring" comment in
include/linux/virtio_ring.h). Callers of vring_size() demonstrate this
problem.
I believe the vring is split across two pages s

On x86, it'll be 4k. You can make it whatever you want for PPC.
Fixing all architectures to be 4k is going to suck for arch

Making the units architecture-specific doesn't solve the problem at all
AFAICS. It doesn't even solv
