Hmm... working for me. Can you please run gdbsx with -d and tar
and send output to me?

Mukesh,

Here's the output from gdbsx -d when trying to view CPUs as thread.

 

BTW, what xen and guest versions?

xen 4.1 unstable sync'd last night

dom0:  Linux kaan-22 2.6.32.16 #1 SMP Mon Jul 12 14:00:17 UTC 2010 x86_64 GNU/Linux

domU: Same: Linux kaan-22 2.6.32.16 #1 SMP Mon Jul 12 14:00:17 UTC 2010 x86_64 GNU/Linux

Thanks for looking into this.

-Bruce
