I am not sure this is a hosted engine question as much as a qemu question.
qemu-kvm will not support auto start of vm's after EIO because of remote possibility of corruption.

Hi,

Quick question, in the scenario eg. the NFS server becomes unreachable and the hosted-engine goes into a paused state. Will other hosts attempt to bring it back up? Should there be a command eg. hosted-engine --vm-resume ?

When this happened, I manually forced it to resume using virsh

        I believe I found the issue and have reported it here
        https://bugzilla.redhat.com/show_bug.cgi?id=1055059

            The interesting thing - trying it with the paused option
            vdsm seems to create the VM

            hosted-engine --vm-start-paused

            vdsm.log http://www.fpaste.org/69604/13900482/

            But I'm not sure how to then proceed to "resume" it.

                Hi,

                With the great help from sbonazzo, I managed to step
                past the initial bug with the hosted-engine-setup but
                appear to have run into another show stopper.

                I ran through the install process successfully up to
                the stage where it completed and the engine VM was to
                be shutdown. (The engine has already been installed on
                the VM and the host has been connected to the engine).

                The issue starts here that the host finds itself not
                able to start the VM up again.

                VDSM Logs: http://www.fpaste.org/69592/00427141/
                ovirt-hosted-engine-ha agent.log
                http://www.fpaste.org/69595/43609139/

                It seems to keep failing to start the VM.. when I
                restart the agent I can see the score drop to 0 after
                3 boot attempts.  The interesting thing seems to be in
                the VDSM Logs "'Virtual machine does not exist',
                'code': 1}}"

                I'm not sure where else to look. Suggestions?

                Cheers,

                Andrew
