Re: [Xen-devel] Re: boot failure with 2.6.27(XCI) git

Run "make menuconfig" after non patched checkout
and make sure there is no option for Xen Privileged Domain
to be enabled. Seems just like vanilla.
Keir doesn't want XCI-specific bits, that's my understanding.

I am using "http://xenbits.xen.org/git-http/xenclient/linux-2.6.27.git". I thought its xenified like 2.6.18. The XCI patchqueue does show more config options(very similar to pvops though), which I am compiling with now.

But, then I don't get the drift of Keir's comment in the other thread :

" The patchqueue is the XCI-specific bits, right? We'd just have a plain
  non-patchqueued got tree for mainline development at least, I think."

Maybe I am missing something. What exactly is this 2.6.27 git ? Is it a forward port of 2.6.18.8-xen or some relative of pvops ? From the code structure, it looks similar to pvops.

Not patched branch 2.6.27 git won't give xenified kernel.
Check "make menuconfig"
As far as i understand XCI queue would give an  option Xen Dom0 support, but it seems to contain some XCI stuff not needed for regular
xenified kernel.

I am using a simple (default config) linux-2.6.27, without XCI patch-queues. The display just blanks out during xen boot. I have a core2-duo machine. And, I am able to boot fine with both pvops and 2.6.18 kernels on this machine. I wish I could give more info, but I have none !

It is important for me to move my development environment to 2.6.27, given the platforms we use.
If there are any suggestions on howto go about debugging this, let know. Does xen support remote serial debugging ? If yes, how to enable it ?

PS : I have attached the config file, just in case
