I don't know what happened but I'm pretty sure you can recover
the domains removing the file stored by the pause command:

# virsh managedsave-remove domainname
# virs start domainname

As for the underlying problem , it happened to me once and I thought
it was caused by a full partition. Notice the saved state files won't
go to the storage pool directory. In my system those files are kept on:

     /var/lib/libvirt/qemu/save/

Hope this helped a little bit.
