Afraid I haven't finished producing the supplemental packs yet (might be a few 
weeks till I get around to finishing that stuff off). I was aiming to allow the 
supplemental packs to work in both cases, if I can.

Thanks for the help/advice all. I did have root squashing disabled, but 
something else must've been playing up. I did the build on another machine and 
it's working now. At least, the ALLINONE vm booted and is 
running, so fingers crossed!

On one of the wiki pages, it says that an Openstack supplemental pack is in the 
works, would it be safe to assume this would be a production oriented pack, 
rather than the devstack style dev oriented setup?

6.0.0 should work fine.

I must have gained some weak mind reading powers, and I just wrote a few more 
wiki pages.

Here is the best place to start:

I actually just added this wiki page (still a work in progress really):

Hope that helps,

In hindsight, that makes sense (though I swear I disabled root-squashing). I've 
been having other issues now, so quick question;

Most guides referer/specify XenServer 6.0.2, should 6.0 work (due to 6.0.2 
being temporarily unavailable?).

I'm going to try now with XenServer 6.0 and build remotely.

Another quick question:

Should this all work on a completely vanilla install of XenServer or XCP or is 
there any prep-work not mentioned anywhere, or any steps a complete Xen newb 
may miss?

I've never seen that kernel panic before.  If you're building on an NFS share 
though, that often screws up the permissions.  You could have root-squashing 
turned on, and then every file that's supposed to be owned by root is owned by 
an unprivileged user instead.  It wouldn't surprise me that this freaks out the 
init process.

I'd try building somewhere else and see if that helps.  Or see whether you've 
got root-squashing or some other permission-modifying option turned on.

Hi all,

I'm not sure if this is the right place for this (and if not, can anyone point 
out where).

I've used the devstack scripts to try to set up Openstack on both XenServer 6.0 
and XCP 1.5 using the following guides:

Wether on XenServer or XCP, I always seem to hit the same issue. When the 
ALLINONE VM is fired up, it shuts down after a few seconds with a kernel panic 
( as seen here: The same issue occurs with the 
domU_multi scripts too.

A note, in case it may affect the build scripts somehow, For external storage, 
rather than using a different machine, or external USB, I've mounted /root to 
an NFS share before running

We've currently got a Diablo Openstack installation up and running using 
StackOps, but I'm currently trying out essex on some spare machines (both to 
get to know it, and an attempt to see if running with Xen is of any advantage 
to us).
