Currently, dump support is always enabled by setting the respective plaintext control flag (PCF). Unfortunately, older machines without support for PV dump will not start the guest when this PCF is set. This will result in an error message like this: qemu-system-s390x: KVM PV command 2 (KVM_PV_SET_SEC_PARMS) failed: header rc 106 rrc 0 IOCTL rc: -22 Hence, by default, disable dump support to preserve compatibility with older machines. Users can enable dumping support by passing --enable-dump to the configure script.
