Hi Konrad,

I’d like to propose an exception for this one. The title is perhaps
underselling it: although it is a protocol extension (and hence a new feature)
the main motivation is to fix a bug in hvmloader which causes HVM guests to
hang during booting on a busy machine. The bug is fairly easy to reproduce with
~200 VMs: you’ll probably find at least one failed to boot.
The patch set has got to a v4 but needs a little bit of work to clarify the
relationship between the closing signal and the existing RESET_WATCHES xenstore
protocol request.
I may be pushing my luck here :-) but I’d like to propose an additional
exception for a feature not on your list:
* xl, libxl: add support for ‘channels'
This has got to a v6 and I believe the API and implementation is stable. It
mainly needs some review of the xl config file parsing changes. This is
definitely a new feature and not a bug fix. I’d mainly like to make the API
official so that I can depend upon it in libvirt.
Thanks for your consideration!
Dave Scott
