    It currently doesn't because the libfsimage ext2fs-lib module is linked
    against libext2fs, which doesnt have ext4 support in XCP.
    Instead, XCP should use the ext2fs module that comes with libfsimage,
    which has ext4 support.
    Most new releases of distributions has it as their default filesystem.
    Most notably, Ubuntu 10.04

Also Fedora 12, Fedora 13, upcoming Debian 6.0 ("Squeeze") and RHEL6.

Well, this is not the Xen issue here. We're having this fixed in RHEL-5 by simply reinstalling the e2fsprogs package to the latest one, although in case of RHEL-5 it's been renamed to e4fsprogs. The simplest thing you can do about this is to reinstall the e2fsprogs package on the host machine and it will be working fine - at least it was when I did test it on RHEL-5 some time ago.

Simply put, reinstalling the e2fsprogs to the latest version will do the job and allow ext4 functionality to pygrub.

    An easy way for the build to use ext2fs instead of ext2fs-lib, is to not
    have ext2fs/ext2fs.h present.
    Alternatively this patch hard codes it.
