I’ve been working on xapi since 2006, on pretty much everything from the domain 
handling code (VM start, shutdown, migrate etc) up through the metadata 
handling to the pooling (host clustering) logic (including HA). More recently 
I’ve been helping out with the effort to split xapi into co-operating daemons 
by moving most (almost all) of the domain handling code to xenopsd and by 
removing as many of the platform dependencies as possible to make the code 
‘just work’ on unmodified Linux distros.

I’d like to help xapi improve by:

1. resolving any remaining conflicts between higher-level cloud orchestration 
layers (cloudstack, openstack) and the host clustering layer. This means 
pushing in the direction of cross-pool shared storage and better support for 
‘pools of one’.

2. making use of libxl and libvirt where we can

3. running as many of our services as ‘unikernels’ (e.g. via MirageOS) as 
possible to make the overall system more robust (e.g. by allowing individual 
kernels to be rebooted rather than taking down dom0 and therefore the host)

Cheers,
Dave
