I will check and see if I still have it, but I have moved on to other = work and have already destroyed that build/test environment.

[Manish] Please it would really help

I would love to give you a link to Linaro-generated build output, but = we are still in the process of getting that setup and running as well.

If you follow the steps in the document (or the steps in the script), = you end up having to build both xen and xen tools.  You can not use an= y of the distro-provided packages.

[Manish] I have built the tools and my ubuntu is used as dom0.
 
You will also need to build libvirt, as the libvirt in the distro pack= ages does not have xen support enabled.
[Manish] The build fails with trivial errors like test c code does not= have main. It appears that something is missing in my setup and I need to = spend more time on it, which at the moment I don't have.

What version of Ubuntu are you using?
[Manish] Using the  link given on the linaro devstack page. Only = difference is I used the rootfs.

/dev/urandom is a common Linux device for pseudo-randomness, see
= http://en.wikipedia.org/?title=3D/dev/random. It is not Xen specific or=
board specific. I don't know why you don't have it in your installation.
Have you tried creating it?

mknod -m 444 /dev/urandom c 1 9

[manish] I am running in chroot environment so it could be an issue.
Btw Is it possible to get the libvirtd deb so that i can just test it out i= f it works as desired. Clark can you please fwd.
