I couldn't find config file in /boot or the other place but it's the

related features in config and compiled kernel over and over but
nothing happened!

grep -i xen /home/MJina/linux-3.2.7/.config
I previously said that it won't work even when I mannually start the
services, but if I modprobe xen-evtchn first and try to start services
even thought it says xenstored cannot be started but xend restarts
successfully and xen works.
#modprobe xen-evtchn
# /etc/init.d/xend restart

I suspect your kernel is not compiled with the xen dom0 options.

Probably you will find some answers here:
Okay so then as suspected, your kernel is not exactly according to spec
for a dom0 kernel. The page I linked says you need:
but you have

 Do some other comparisons and see what else is wrong. Since "modprobe"
lets you start xend, probably that is equivalent to =y, but something
else is likely wrong. And if those wrong lines are =m instead of "# ...
is not set" then you can probably modprobe them too (for testing at
least... and then recompile with =y later)

(also I think you're missing CONFIG_X86_IO_APIC=y ... make sure to do a full compare)

eg. What i would try first is copy and paste all the dom0 and domu options from the
page into a file, then sort the file with
sort xenwikidom0config > xenwikidom0configsorted
then do the same with your config, and then do a diff

or I'd write a bash script that takes the key name (before the =) from
the xen wiki page config, and greps your config for the option to see
what the setting is.

And after you resolve this, you should report to whoever created your
kernel config that it should be fixed. (or is that you?)

Why are you using such an old version of Fedora? If ou update to
F17 or F18 you have Xen out of the box.

Yes, I agree with that also... and upgrading a Linux distro release is easy.
