GDB and QEMU
Running QEMU in GDB has proven to be very helpful. Simply copy the gdb binaries (gdb, gdbserver, and gdbtui) on to your OpenXT machine and replace the /usr/lib/xen/bin/qemu-system-i386 script with:
#!/bin/bash
DOMID=`cat /tmp/domid`
let "NEWID=$DOMID+1"
echo "$NEWID" > /tmp/domid
exec gdbserver 0.0.0.0:1234 /usr/bin/qemu-system-i386 -gdb stdio -xen-domid $DOMID -nodefaults -name qemu-3.0 -machine xenfv,max-ram-below-4g=0xf0000000 -m 1024 -drive file=/dev/xen/blktap-2/tapdev0,if=ide,index=0,media=disk,format=raw,readonly=off #-vnc 192.168.2.2:5900 $@
In another window, you can run gdb and do target remote localhost:1234.
