[ipxe-devel] Problem with ipxe on Xen 4.4

When trying to use ipxe on Xen 4.4 it was always using the emulated NIC
(realtek) and not the netfront driver.

I retried with DEBUG=xenbus and saw that xenbus_probe_type failed for the
device: device/suspend/event-channel (I think because it doesn't have a
backend key - it is empty). As this device isn't critical for the usage of
netfront I just commented out the error in xenbus_probe_type for one device
and now it works fine.

Is there any reason failing to probe the type of one device should fail the
whole probe of the xenbus?

I can formalize a patch the prints a warning with DBG and allows it to
continue but I was wondering if there was any downside to that?
