Sorry for the last empty mail (hit the wrong button). Attached is a patch against xen-unstable to improve the error messages in pygrub when the e2fsprogs do not support the newer ext2fs_open2 function. This should help beginners to identify the real problem when pygrub does not work (e.g. on RHEL4).

I also have that problem on fedora core 5. As far as I can see, your fix is only about the error message. But how can the actual problem be solved? I'd really like to use a simple xen config as given in xmexample1, and use the images from xen-get.org.

Yes, my patch only improved the error reporting, not the underlying problem of a too old version of e2fsprogs. Nevertheless FC5 has an appropriate version of e2fsprogs (as well as FC4 btw.).

So your problem is a different problem. As Andrej noted in the other mail, disabling SELinux might help. I remember reading about this already on one of these lists here.

Just for the archives or anyone using pygrub on RHEL4/CentOS4: I have successfully rebuilt and used e2fsprogs from FC4 on RHEL4/CentOS4 and have had no issues so far. YMMV. (Don't forget to rebuild pygrub after installing the new e2fsprogs!)
