I am using xen-libs-3.1.2-2.fc8 kernel-xen-2.6.21.7-3.fc8 xen-3.1.2-2.fc8 and xentop is showing NETTX(k) NETRX(k) at fixed value 0 example NETTX(k) NETRX(k) 0 0

Created attachment 312260 [details] Patch to add sysctl version check for physinfo in kernel
Interface version check between HV and userspace was modified in RHEL5.2 to allow through physinfo calls with newer versions for NUMA extensions. HV and tools have the modification, but kernel does not have it which is needed for xen/ia64. The attached patch on comment #9 adds it in kernel.
Ok, this isn't a userspace bug then - switching to kernel-xen instead.
in kernel-2.6.18-100.el5 You can download this test kernel from http://people.redhat.com/dzickus/el5
