Just to be transparent here, not all possible functionality is tested by the package maintainers (currently Ian and me) before throwing a new package into Debian. This is simply not practically feasible for us. [0] We rely on the upstream tests to know that the upstream Xen code will probably work. For Debian specific things, we do test our own use cases, but e.g. UEFI is not one of them. For this, we rely on active users to report problems and help solving them. So, yes, things like this can happen. Thanks for reporting this. Next step would be to follow Rogers instructions, and provide config dumps, serial console output etc... We're certainly available to include changes / etc to fix things, given proper information / testing reports from the user. But, the user has to actively help to make that happen.
