[Openstack] Can't launch VM with XCP plus OpenStack Essex release version

It is not well documented (I promise to work on that soon), but you should use an EXT3 local SR, not LVM. It is certainly worth moving to EXT3, just to rule a few things out.
I see you are using the Ubuntu XCP packages. This is a version of XenAPI I have not yet started doing much QA on, but I did get a VM started OK when using EXT3. However, I used to get LVM working for the basics with earlier versions of xenapi, so I am shocked that is totally broken on the latest.
Also, what sort of VM are you trying to launch? Is it a three part image with external kernel?
If you want to get going with XenAPI and OpenStack quickly, I would recommend DevStack and XenServer 6.0.2 (free download) or XCP 1.5 Beta. That is the combination I am testing today. Hoping to test Ubuntu XCP and OpenStack in the next few weeks.
Thanks,
John
PS:
I think the problem you are hitting is because there was a recent change in XCP/XenAPI where mounting the VDI into dom0 no longer automatically exposes the partitions of that disk to the Dom0 Kernel, so you need to use kpartx (or similar) to mount to appropriate partition. I can see you are hit this because the device returned is "/dev/sm/<guid>/<guid>" rather than "/dev/sda1" or something like that. I got normal VMs working OK despite this, but have not yet gone through all the XenAPI plugins to ensure all the issues are fixed.
