Unfortunately, older machines without > support for PV dump will not start the guest when this PCF is set. maybe for the long term we could try to fix the stub generated by genprotimg to check the plaintext flags and the available features and refuse to try to start if the required features are missing. ideally providing a custom message when generating the image, to be shown if the required features are missing. e.g. for kvm unit test, the custom message could be something like SKIP: $TEST_NAME: Missing hardware features once that is in place, we could revert this patch > > Nico Boehr (1): > s390x: do not enable PV dump support by default > > configure | 11 +++++++++++ > s390x/Makefile | 26 +++++++++++++++++--------- > 2 files changed, 28 insertions(+), 9 deletions(-) >
