Hi,
The minios source code is in extra/minios. After compiling, I got a
file called mini-os.gz, then I succeed to start a domainU by setting the
kernerl to be mini-os.gz in config file ''minios.conf'' as
follow:
# Kernel image file.
kernel = "/home/test/minios.gz"
The command ''xm list'' show:
Name ID Mem VCPUs State
Time(s)
Domain-0 0 1220 2 r-----
11527.3
minios-120 5 256 1 --p---
1110.5
I got the gdbserver-xen later and run ''gdbserver-xen
127.0.0.1:9999--attach 5''(5 is the domid). Next, run ''gdb
/path/to/minios/exefile'', and
then ''bt'' in gdb, but no stack info.
thanks in advance for your help.
bruce

Run following command from gdb: target remote :9999 and do not forget compile mini-os with symbols. Daniel

I''m not clear about compiling mini-os with symbols, does it make sense that specifing the /path/to/minios-source in gdb cmd line and the gdb would find the symbols infomation automatically? _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel

It means that if you pass path to mini-os executable to gdb everything should work as expected. Daniel
