Thanks Pasi, I did look into debugging via serial console yesterday, system is rack mounted and currently not a viable option for me since it requires admin approval, I am looking into this. Aside from that, I believe xen/next should work with xcp 0.1.1 i.e

1. xen 3.4.3.gz, xen/next kernel. Take tar-pkg built from xen/next, untar it in xcp0.1.1 dom0, modify extlinux.conf to boot from 3.4.3 and new kernel. will this work?

Thanks
