I build and installed Xen (4.1.3)=A0 from source, and I think= I have got it working. Well, almost.
I am using unmodified kernel of Fe= dora16 as my dom0 kernel.

So this is what happened.

I am abl= e to boot into Xen, but the=A0 "xl info" failed with the standard= error message mentioned in the tutorial.
"libxl: error: libxl.c:56:libxl_ctx_init Is xenstore daemon running?
failed to stat /var/run/xenstored.pid:
No such file or directory cannot init xl context"

I checked the xen common problems page, http://wiki.xensou= rce.com/xenwiki/XenCommonProblems.html and did some troubleshooting.
I was infact running Xen dom0, since I got this output. 
# ls /=
proc/xen/
capabilities  privcmd  xenbus=
  xsd_kva  xsd_port

# cat /proc/xen/capabilities
control_d

But my= evtchn and gntdev were not loaded. Hence below command returned nothing. <= br>
I ran commands "modprobe xen-evtchn" and "modprobe gn= tdev" to manually load those drivers.
Then went to /etc/init.d to manually restart xencommons and got this.
#= ./xencommons restart"=A0
Stopping xenconsoled
WARNING: Not sto= pping xenstored, as it cannot be restarted.
Starting xenstored...
Set= ting domain 0 name...
Starting xenconsoled...

Now "xl info" gave the right outpu= t.

So do I need to do this everytime I boot ? Why does it not work = right off the boot automatically ?
Comments please ?


Thanks,=
Ranjith
