I'm not sure how this can relate netconsole since this happens before
the guest even runs, doesn't it?

As i see it, netconsole driver requires ndo_poll_controller from the
device's controlling driver (function __netpoll_setup in
net/core/netpoll.c), a thing that is not supported currently in
xen_netback driver which is the driver that runs on dom0 and serve
VM's virtual interface.

Which domain is using netconsole? Is it dom0 or domU? What parameters do
you give it?

I assume it is the domU but if that's the case I don't see why a netback
rather than netfront patch would be required.

Or is dom0 doing netconsole where the log receiver is a domU?
