I recently had a (probably) similar issue, with xcp-squeezed consuming all the memory and then causing a reboot. I was using a pae kernel (3.0.0-16.generic.pae), and the workaround, as suggested by the Kronos team, was to increase dom0 memory with a boot parameter to the hypervisor. I used dom0_mem=3G.

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.

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 /Kieran
