[Xen-devel] xen-gdbserver and missing tty in domU

[sanket hase <shase@xxxxxxxxxxxxxx>]

Hi Folks,

We have compiled freebsd domU with debug info. ( freebsd 7.0 domU 
running on debian etch 4.0 dom0 , xen 3.0.3 hypervisor)
Now I have 2 thing to ask

1. This kernel ( build  with -DNO_MODULES) crashes and I was trying to 
attach xen-gdbserver to its core dump.
 Kernel panics when I attach my gdb client ...

***********************
 (gdb) target remote 127.0.0.1:9999
Remote debugging using 127.0.0.1:9999
[New thread 0]
[Switching to thread 0]
panic (fmt=Cannot access memory at address 0xc06e9384
) at ../../../i386/include/pcpu.h:213
213     ../../../i386/include/pcpu.h: No such file or directory.
      in ../../../i386/include/pcpu.h
warning: no shared library support for this OS / ABI
**************************

I came across a few posts which emphasize on  setting "domu_debug=y" in  
xen/kern.mk file. Need I recompile dom0 so that
 flag takes an effect ? Need we do anything else apart from setting 
this (domu_debug) flag  to get gdbserver running ?
2. Also ,
  xm create -c  /etc/xen/freebsd     gives =>
  Using config file "freebsd".
  Started domain freebsd
  xenconsole: Could not read tty from store: No such file or directory

 I thought this bus was fixed ( as per bugzilla ) . Any pointers ?

Thanks,
Sanket
