http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/UserProvidedKernels.html was mentioned above by Bastian Blank. At http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=727736#20. That document states, in the section `Limitations of PV-GRUB', that * PV-GRUB can boot kernels compressed using the gzip, bzip2, lzo, and xz compression formats. It also states that one of the reasonss of their choice of PV-GRUB is that it understands standard grub.conf or menu.lst commands, which allows it to work with all currently supported Linux distributions. I still think there is a problem with newer Debian's kernels and xen's PV domU. I'll try to obtain access to an aws vps to boot such a kernel and get the boot log. Like I wrote, such a kernel failed with another xen commercial provider. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
