Hello,

I've downloaded the xen 4.0.1 version as it is explained here:
http://wiki.xensource.com/xenwiki/Xen4.0

<http://wiki.xensource.com/xenwiki/Xen4.0>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:
http://wiki.xensource.com/xenwiki/XenParavirtOps


<http://wiki.xensource.com/xenwiki/XenParavirtOps>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:

xend.log

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

Thank you!

[-- Attachment #1.1: Type: text/plain, Size: 7101 bytes --]

I tried another approach.

Since I assume that my problem is with modules loading, I've compiled the
kernel with xen-evtchn and xen-gntdev as modules. Now, I can load them with
modprobe. They do appear loaded in lsmod

% lsmod | grep xen
xen_gntdev              7486  0
xen_evtchn              4617  1

It seems that xend is running, as we can see in a ps:

% ps ax | grep xen
   24 ?        S      0:00 [xenwatch]
   25 ?        S      0:00 [xenbus]
  851 ?        S      0:00 avahi-daemon: running [xenserver-laptop.local]
 2101 ?        S      0:00 xenstored --pid-file /var/run/xenstore.pid
 2105 ?        SLl    0:00 xenconsoled
 2109 ?        S      0:00 /usr/bin/python /usr/sbin/xend start
 2110 ?        Sl     0:00 /usr/bin/python /usr/sbin/xend start
 2254 pts/0    S+     0:00 grep --color xen


But /var/log/xend.log shows that I have an exception during xend start:

[2010-10-28 11:10:52 2110] INFO (SrvDaemon:331) Xend Daemon started

And I cant call any xm bin, as for example:

% xm list
Error: Unable to connect to xend: No such file or directory. Is xend
running?
(1) %


So, I'm kind of stuck here. Any Ideas?

Thank you all,

Do you have /proc/xen/privcmd? You might need to configure that into your
dom0 kernel build or something.

Yes, I do have /proc/xen/privcmd. I suspect that something is missing in my
config. I'm not sure if I understand what you said. What do you mean by
configure privcmd into dom0 kernel?

% ll /proc/xen
total 0
-r--r--r-- 1 root root 0 2010-10-28 11:08 capabilities
-rw------- 1 root root 0 2010-10-28 11:08 privcmd
-rw------- 1 root root 0 2010-10-28 11:08 xenbus
-rw------- 1 root root 0 2010-10-28 11:08 xsd_kva
-rw------- 1 root root 0 2010-10-28 11:08 xsd_port

Thank you!

Oh, hang on, the problem is probably that you have a version mismatch
between your hypercvisor and your tools in dom0. They need to be installed

* Xend does not start

Hello:
 
We have seen instances of "unable to connect, is xend running?", in
situations where machine was hard-powered down i.e. without proper
shutdown.
 
Even if we try to xend restart, we are unable to start xend.
 
Is there a "reset" or recovery mechanism available?
 
Thanks
-Kaushik
