This requirement is not as broad as you make it sound. All which is really required is the ability to slurp in or write out a blob of bytes to a service running in a control domain, not actual ability to read/write files in dom0 (which would need careful security consideration!). For the old qemu-traditional stubdom for example this is implemented as a pair of console devices (one r/o for restore + one w/o for save) which are setup by the toolstack at start of day and pre-plumbed into two temporary files.
