Changed * Changed Docker images repository from DockerHub to Amazon ECR. Fixed * Snapshot related host files (vm-state, memory, block backing files) are now flushed to their backing mediums as part of the CreateSnapshot operation. * Fixed race between vcpu initialization and emulation thread which could potentially lead to segmentation faults. * Fixed the SSBD mitigation not being enabled on `aarch64` with the provided `prod-host-setup.md`, by force-enabling it.
