+Thank you fro the tip about using kernel-server-3.4.24-1.
+After switching to this kernel, and rebuilding initrd, with the command:
+mkinitrd-mkinitrd --with=xen-blkfront --with=xennet --with=xen-netfront
+initrd-3.4.24-server-2.mga2.img 3.4.24-server-2.mga2
+
+It worked on Amazon EC2 and I have a nice Amanzon EC2 Mageia2 box.  I'll
+create a clean AMI for others to use in the next few weeks!  I released a
+Mandriva 2011 public AMI about a year ago.
+
+It went much better than my attempt with 3.3.8-server-2.mga2, which
+complained about the compression format.
+I see in the change log, you have switched it back to gzip.
+
+Searching for the gzip signature, using
+od -A d -t x1 vmlinuz-3.3.8-server-2.mga2 | grep '1f 8b 08 00'  does not
+find it, for 3.3.8, but searching for the xz sig, using
+od -A d -t x1 vmlinuz-3.3.8-server-2.mga2 | grep -i 'fd 37 7a 58 5a 00',
+return a match.
+
+I found what is a little bit of a trap for people...  funny now I think
+about it.
+
+the output from running file vmlinuz*
+
+vmlinuz-3.4.24-server-2.mga2: Linux kernel x86 boot executable bzImage,
+version 3.4.24-server-2.mga2 (iurt at ecosse.mageia.org) #1 SMP Tue Dec 18,
+RO-rootFS, swap_dev 0x3, Normal VGA
+vmlinuz-3.3.8-server-2.mga2:  Linux kernel x86 boot executable bzImage,
+version 3.3.8-server-2.mga2 (iurt at jonund.mageia.org) #1 SMP Mon Jul 30 ,
+RO-rootFS, swap_dev 0x2, Normal VGA
+
+It is easy to assume that bzImage mean's bzip.. but it does not.. it means
+big zimage.  the actual compression type is not displayed using the file
+command.
+
+I wonder if a patch to the file command to also output the compression type
+for kernel images, might be a good idea?
+
+Regards
