Based on [1], it looks like the answer is currently no, based on the
following line in the kernel config file:
# CONFIG_SHARED_KERNEL is not set
The description of that option says
Select this option, if you want to share the text segment of the
Linux kernel between different VM guests. This reduces memory
usage with lots of guests but greatly increases kernel size.
You can build a custom kernel using that option if you wish. It works
like this[2]:
$ apt-get source linux
# apt-get install build-essential fakeroot
# apt-get build-dep linux
$ cd linux-<version>
$ fakeroot debian/rules source
$ fakeroot make -f debian/rules.gen setup_s390_none_s390x
$ cd debian/build/build_s390_none_s390x
$ scripts/config --disable DEBUG_INFO
$ scripts/config --enable SHARED_KERNEL
$ cd ../../..
$ fakeroot make -f debian/rules.gen binary-arch_s390_none_s390x
Hope that helps,
Jonathan
