At no point did I say that it was safe to use libguestfs on live VMs
or that you would always get consistent data out.

But the fact that it can fail is understood, the chance of failure is
really tiny (it has literally only happened twice that I've read
corrupted data, in years of daily use), and the operation is very
useful.

So I think this patch series should either not lock r/o VMs, or should
add a nolock flag to override the locking (which libguestfs will
always use).

That's all I have to say on this.

Rich.
