Humm... I wonder if thats why you are not seeing this problem.It is usually the other way round, since debug builds contain lots of cross checks and assertions that are not included in production builds. Certainly a few bugs do only crop up in production builds, and so we test both types of builds ourselves, but it's rare and the first thing we'll do if we see a production-build crash is to try and repro with a debug build. This must be one of those rare ones ;') Debug build works, release build fails. I did a 64bit XEN debug build and tried booting 64bit RHEL4U2 2CPU 256MB HVM guest and it boots fine. I then did a 64bit XEN release build and tried booting the same guest and I crash in vmx.c:2268. dom0 console output for both debug and release builds is attached. This is c/s 11616.
