# Prevent installation for CPUs that are too old
# SLE16 image panics on CPUs older than x86_64_v2 (i.e. x86_64) (bsc#1249593), so we need to block migration before getting into the image.
# We need the ZYPP_READONLY_HACK here since we are running inside a zypper transaction; without this the invocation of zypper will fail due to locking issues.
