Hi,
gdbserver-xen coredump after i step through a few lines of code.
build dom0 with debug_domu. Enable debuginfo and frame pointer for dom
U and attach the domu with gdbserver . In gdb put breakpoint at say
sys_open and after going through few lines of code gdbserver-xen
coredumps.
The resulting core file has the below stack
$gdb /usr/local/bin/gdbserver-xen ./core
