Hello,�

I've downloaded the xen 4.0.1 version as it is explained here:

So, I've made a clone from repository, with the following command:
hg clone -r RELEASE-4.0.1 http://xenbits.xen.org/xen-4.0-testing.hg
And finally I've built xen, tools and stubdom.


I was looking for a paravirtualized domain, and so I follow the instructions from here:


So, I am able to boot dom0 successfully, but apparently xend its not starting.

A few things that I have noticed:�

1) lsmod does not list evtchn and neither gntdev, and they are not compiled as a Module. I have tried also to insert them with lsmod, and of course, I dont have them.
2) The nodes appear in both /proc/misc and /dev/xen, and the numbers are correct

% cat /proc/misc�
�52 freefall
224 tpm0
�53 network_throughput
�54 network_latency
�55 cpu_dma_latency
�56 device-mapper
��1 psaux
200 tun
�57 pktcdvd
228 hpet
�58 blktap-control
�59 xen/gntdev
�60 xen/evtchn
229 fuse
�61 ecryptfs
231 snapshot
227 mcelog
�62 rfkill
�63 vga_arbiter
% ll /dev/xen�
total 0
crw-rw---- 1 root root 10, 60 2010-10-27 17:32 evtchn
crw-rw---- 1 root root 10, 59 2010-10-27 17:32 gntdev

3) I am really running dom)
% cat /proc/xen/capabilities ��
control_d

4) /var/log/xen shows the following errors:

Does anyone have any Idea of how can I start xend correctly ?

Thank you!
