Patches against which kernel?
Currently generates the xen kernels from: kernel-xen-2.6.12-1.13_FC5.src.rpm
For this the related xen arch files could be generated and this could be used as a starting point. Otherwise it is going to be painful manual process to create the equivalent kprobes patch for Xen. However, once there is a patch, Stephen thought it was quite likely that the xensource people would be willing to accept it.
One open question was whether Xen allows the text of the kernel to be modified.
Dan Stekloff posed this question on the Xen IRC, and the answer was yes, a guest kernel can modify its text.
