debugging udev on ubuntu

[Tapas Mishra]

Hi, one of my Ubuntu machines  where I am trying to create Xen based
virtualizaton setup (as the machine is non VT)

 I am not able to create guest Operating system on it.Having digged
through the logs which can be seen here
/var/log/xen/domain-builder-ng.log
http://pastebin.com/8W45hjCV

/var/log/xen/xend-debug.log
http://pastebin.com/634FaJQP

/var/log/xen/xend.log
http://pastebin.com/y7wWs19K

/var/log/xen/qemu-dm-ubuntu.vm.log
 http://pastebin.com/cRNqUGRf

/var/log/xen/xen-hotplug.log is empty

xend.log also seems weird. It should show something like

While  it simply shows

[2011-03-10 13:30:04 1705] DEBUG (DevController:628)
hotplugStatusCallback /local/domain/0/backend/vif/1/0/hotplug-status.
[2011-03-10 13:31:44 1705] DEBUG (XendDomainInfo:3053)
XendDomainInfo.destroy: domid=1

Perhaps udevd is dead?


I am not able to understand how do I trouble shoot it.
Can any one help in debugging this part as what more should I look in?
