Ok, by changing from a pvfb vnc inside the stubdom config, to vnc in the
master config, I now get output into my qemu-dm log file, and so can see
the debug printf's I added in. It also means a msg from qemu is appearing:

Could not initialize device 'tap'

Which is coming from within vl.c:

    for(i = 0;i < nb_net_clients; i++) {
        if (net_client_parse(net_clients[i]) < 0)
            exit(1);
    }


The qemu cmdline parameters are being reported as follows:

"main" "-d" "23" "-domain-name" "wintest-sd" "-videoram" "4" "-vnc"
"192.168.254.135:0" "-vncunused" "-vcpus" "1" "-boot" "c" "-acpi" "-net"
"nic,vlan=1,macaddr=aa:00:00:12:23:34,model=e1000"
"-net" "tap,vlan=1,ifname=tap23.0,bridge=eth0"


Any debugging I could add that could track down the cause of the above
error, or is this something you recognize?
