[PATCH 0/2] Make savevm versioning compatible with upstream QEMU

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Right now, there is no way savevm versioning can be compatible with upstream
QEMU because KVM adds fields to existing savevm structures without incrementing
the versions.

If you assume that KVM will eventually merge into upstream QEMU, this means that
eventually KVM is going to have to break backwards compatibility with itself
to resolve this issue in a non-graceful way.

So let's do that now instead of doing it later when the situation is only worse.

I'm happy to allocate particular version identifiers for KVM to avoid future
conflicts.  I believe we should try to eliminate the existing differences so
that we can converge in the future on a common versioning scheme.
