get_e2uuid: /sbin/tune2fs: Filesystem has unsupported feature(s) while trying to open /dev/vda1 Couldn't find valid filesystem superblock. at /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi/Sys/Guestfs/Lib.pm line 735.
The problem is that on RHEL 5, the ext4 utilities were in a separate package and all had separate names (eg. mke4fs instead of mke2fs). These programs can in fact create and handle ext2/3 as well, so on RHEL 5 we should just use them unconditionally. We already got this right for mke4fs: http://git.annexia.org/?p=libguestfs.git;a=blob;f=daemon/ext2.c;h=85ddce52525b1fca02dd8ac524f81a0f64ead93f;hb=HEAD#l339 but not for tune4fs etc., so that is what we need to change.

libguestfs-1.0.85-1.el5.9 has been submitted as an update for Fedora EPEL 5. http://admin.fedoraproject.org/updates/libguestfs-1.0.85-1.el5.9
Please try this backport which fixes the issue for me. There is another semi-related ext4 bug that we found in the guestfs_e2fsck_l command[1]. However unless you are resizing ext4 partitions, it shouldn't affect you. If you _are_ resizing ext4 partitions, let me know and I will backport this fix also.
