Any thoughts on this? Is the guest memory often helpful in debugging when the qemu process segfaults? This feature also seems useful if somebody is running a sensitive workload, such that the non-sensitive qemu state can be dumped independently of the guest state. In that case, perhaps there should also be an option that allows the guest to be dumped on a segfault, now separately? Thanks, -Jason
