I haven't looked deeply into 'xl' but..

>From the recent Xen summit, I walked away thinking 'xl' didn't have the callback mechanisms (e.g. Cleanup etc) and this helped it stay stateless while falling short of full 'xm' replacement. This email thread indicates 'xm/xend' will be deprecated in due course of time. Did I miss anything here ?

Is migration of VMs from 'xm' managed hosts to 'xl' managed hosts expected to work ?

I think moving away from commonly used xend/xm could be a bit of a thorn particularly if the 'xm' to 'xl' migration isn't expected to work.

Thoughts ?

Thanks,

Indeed.  I think at this point it's probably OK to submit features for
libxl only and not add them to xm/xend too.
