Hmm, bad error message :-( We might also need todo a chown() in the restore path to allow QEMU to read it. NB there is no compatability between QEMU version, so if you have upgraded your install of QEMU between the time you saved & restored it is very likely to crash & burn.
How difficult would it be to set up named pipes for save and restore operations, and splice from those pipes to the actual files on the libvirtd side? Seems much preferable from a security perspective to chown'ing things around, and (unlike pipes set up ahead of time with pipe() and friends) shouldn't be disrupted by a libvirtd restart.
