I had to make a change to the vblade.c code... there's a packet size check 
that seems to fail... I have no idea why it is only an issue in XEN 
configurations, but it seems that it is... Here's the change:
--- vblade-14/aoe.c     2006-11-20 09:48:05.000000000 -0800
+++ vblade-14.tom/aoe.c 2007-04-17 19:07:35.000000000 -0700

                        perror("read network");
                        exit(1);
                }
-               if (n < 60)
+               if (n < 20)
                        continue;
                p = (Aoehdr *) buf;
                if (ntohs(p->type) != 0x88a2)

that seems to be sufficient to make vblade work "on the same box"
