tests/migration: Skip tests for ppc tcg
PPC tcg seems to be failing migration tests quite regularly; we believe this is TCG bugs in dirty bit updating; it's not clear why PPC fails more but lets skip for the moment. $ ./tests/migration-test /ppc64/migration/deprecated: OK /ppc64/migration/bad_dest: Skipping test: kvm_hv not available OK /ppc64/migration/postcopy/unix: Skipping test: kvm_hv not available OK /ppc64/migration/precopy/unix: Skipping test: kvm_hv not available OK Signed-off-by: Dr. David Alan Gilbert <dgilbert@redhat.com> Reviewed-by: Laurent Vivier <lvivier@redhat.com> Message-id: 20180706143105.93472-1-dgilbert@redhat.com Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
