I installed from debian etch and do not seen anything like that.
Will I need the source from here?

Looks there are some current abi patches but not win4lin.
Is there any commitment to maintain kernel compatibility at least over a
major version?
New version of xen have been coming out pretty often and it could get
challenging if I have custom kernels.
This brings me back to HVM. Does linux have good disk and network
performance using HVM?
Thanks
