Hi Daniel thanks for your reply! You mentioned finding a new LZ4
library but grub2 already looks to support lz4 compressed kernels. The
issue is that they don't look to be supported under the Xen platform
with a target of x86_64.
Grub does "support" lz4 compressed kernels by letting them decompress
themselves.
This can't work with Xen PV mode as grub needs to access the ELF notes
in the compressed part of the kernel, so grub needs to do some
decompressing itself.
