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.

Cheers,
John

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 prepare_guest.sh 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:
http://wiki.openstack.org/XenServer

I actually just added this wiki page (still a work in progress really):
http://wiki.openstack.org/XenServer/PostInstall

Hope that helps,
John

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.

Cheers,

Ewan.

Subject: [Openstack] Devstack +XCP/XenServer Kernel Panic

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:

http://wiki.xen.org/wiki/XCP_DevStack
https://github.com/openstack-dev/devstack/blob/master/tools/xen/README.md

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: http://imgur.com/i85fC). 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 prepare_dom0.sh.

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).

Thanks
