[Kimchi-devel] [PATCH] [Kimchi] Fix max number of memory slots for Ubuntu on Power

[Lucio Correia]

Ubuntu ppc64le has not yet pushed upstream qemu support
for 256 memory slots devices. Thus guests created by Kimchi
on that distribution cannot be started without editing XML
provided by Kimchi.

This commit is to be reverted once Ubuntu's qemu is updated
with 256 memory slots support.
