Ok finally I am answering my question I have done the way I mentioned
above as git pull was costly.
Things have worked finally without any error and almost perfectly.
for tools I had to use
 make install-tools PYTHON_PREFIX_ARG=

and after that I rebooted

Let me know if any one sees any error here.I think upto here things
are absolutely perfect.
I have used the .config file you mentioned in this thread and was able
to get all options as you mentioned.
For just sake of information I am mentioning what I got in xen.log
http://pastebin.com/ZJ9BCMLq
and xend-debug.log
http://pastebin.com/C6DQ5DP3

I was able to get Dom0 booting.
I wish if after this I can use my wireless also in Dom0.


The device on Dom0 I has PCI Id 14e4:4315


when booted with this new kernel pv-ops Dom0 kernel 2.6.32.27 checked
lspci -vnn
it shows

where as in the old kernel (which still is there with working wifi
this is without Xen)

lspci -vnn shows

Kernel driver in use: wl
Kernel modules: wl, ssb

In the above kernel the wifi works and you can see a wl driver in
use.How ever in the newly compiled  pv-ops kernel I mentioned wl
driver is missing.Is there a way to load it from system some how or
what more can I do to get my wifi back.When I had installed Ubuntu
then while being connected from my LAN from Ubuntu 10.04 (64 bit) gui
I had installed driver

in (default 2.6.32.24 kernel)

System->Administration-->Hard Ware Drivers-->Broad Com STA driver I
but if I do the same in new 2.6.32.27 kernel which I compiled)
System->Administration-->Hard Ware Drivers-->Broad Com STA driver

get a failure message which says me to check
/var/log/jockey.log
and here is the jockey.log
http://pastebin.com/VBTLGw42
how ever I feel the problem is rather simple and some thing is missing.

/etc/modprobe.d/blacklist.conf I have


# replaced by b43 and ssb.
blacklist bcm43xx


 also checked wl.ko driver in the old working kernel is at following location

/var/lib/dkms/bcmwl/5.60.48.36+bdcom/2.6.32-24-generic/x86_64/module/wl.ko

If you notice in above output it has path to 2.6.32-24-generic kernel.


I do not have any problem in using my wifi when I boot with
2.6.32.24 (which is what was installed during installation from Ubuntu CD)
but when I boot
2.6.32.27 (which I had compiled) I do not get my wireless back and
lspci shows above output as I mentioned where wl driver is missing.So
how can I get this back?

Is it possible to have some thing like


/var/lib/dkms/bcmwl/5.60.48.36+bdcom/2.6.32.27/x86_64/module/wl.ko

for new kernel that I compiled.Let me know how can I get beyond this
point.I feel this can give me the wifi back but how to go for this one
I am not clear.
