I notice that recent KVM is incompatiable with older versions.
Using a KVM image created on 2.6.24 will crash on 2.6.25 (or
vice versa). It appears that Ubuntu Hardy has incorporated the 2.6.25
update even though it claims to be 2.6.24.
This is reproducible on Intel (64bit) kernel. Was this intentional?
is it documented?

This isn't intentional. What is the guest and how does it crash?
I've been using the same image for most of KVM's development life cycle
without having issues.

I'll see if I can get a backtrace, it isn't reliably reproducible.
