W hat do w e do for xen testing • Find bugs and help I ntel developers to fix them • Validate big xen 3 .0 release ( xen-3 .0 , xen- 3 .0 .2 etc) • Validate Xen distributions from OSDs • Develop test cases � Functional & performance tests � Focus on unmodified guest • W ork off xen-unstable, results published daily � Focus on VT-x / VT-I � Basic xenU boot test 3 2 0 0 6 / 9 / 8

I ssus w e have • HVM blocked m any tim es in xen-unstable � Is it possible to have HVM boot test before checkin to xen-unstable, just like xenU? • W ith default build config, build tim e alm ost doubles than build w ith “xen0 + xenU” � Default build config builds much more modules than “xen0+ xenU” 7 2 0 0 6 / 9 / 8
