I recently upgraded my laptop from 6.x to NetBSD 7.0 i386. Could not compile xentools/kernel 4.2 (it won't complie on 7.0 seems to be documented on xen wiki already), so had to resort to 4.1.
I noticed performance degradation with Xen Dom0 (even with no guest running) as well as a Linux DomU running on it. Difficult to put it objectively, but it feels when switching between windows, the screen doesn't refresh instantaneously as it would normally do etc. As 2 things changed simultaneously, Upgrade to 7.x and downgrade to xentools/kernel 4.1, I am not sure whether either of them would have caused this. (In theory, could be a graphics issue, but unlikely since with generic 7.0 kernel I don't see above issue.) Would appreciate advice/pointers/discussion on this. Mayuresh
