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

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”
