Thanks for the log. The xenbus enumeration is definitely working since we see a "vif/0" message in the kernel output. Unfortunately I don't think the netfront driver provides anything more verbose than the single "xen_netfront: Initialising Xen virtual ethernet driver" message that you're already seeing.

Since you seem to be reliably reaching a controllable userspace, you could try patching the kernel and/or initrd to dump out more diagnostic information. For example, patching xenbus_xs.c to display all xenbus reads and writes would help.

Alternatively, you could try reproducing the problem in a local XenServer instance. That would allow you to examine the state using xenstore-ls from dom0, without having to patch the guest kernel/initrd.
