Hi all, I am trying to perform single-stepping and instruction emulation both in Xen-3.2.1. I am using the following approach: First, I mark a guest page "not present" inside the shadow page table so that I could intercept any operation that involves this page.

Hi Rahul, If you're certain that your problem isn't as Stephen suggested, you might want to have a look at this: --- (From http://ebtables.sourceforge.net/brnf-faq.html <http://ebtables.sourceforge.net/brnf-faq.html> ) How do I let vlan-tagged traffic go through a vlan bridge port and the other traffic through a non-vlan bridge port?
