Hi Michael,
I didn't save the original thread when you posted this, so my apologies for breaking threading. :)
I just tried this kernel on Fedora 14 x86_64 and, like several of the previous attempts, it simply reboots after xen.gz finishes booting (at least, this is what I can guess, as the screen is black). This is despite hearing other report much better success. So I was wondering if these kernels have been tested against dom0 with an encrypted ext4 root partition?
I'm going to try the 4.0.2-rc1 xen hypervisor shortly. In the meantime, is there anything I can do to help narrow down the potential source of the problem?
Thanks for the continued hard work. :)
