Hi Mukesh:
I tried your gdbsx stub but hit a couple errors.
I didn’t find an explanation with google; nor on the xen-devel mailing list yet.
Thought I’d ask ya.
I installed Ubuntu-14.04 Server with OpenXenManager on my Xenon workstation and have
A Xenon blade also with Ubunto-14.04 and OpenXen. Seems to run about the same on both
Machines.
This afternoon I pulled the Xen source with git from
xenbits.xen.org and build it.
The version of gdbsx that I built on my workstation is having problems attaching to Domain-0.
I tried this on the host. Do I need to create a shell to a Domain-0 instance or something?
