Hi Ricardo,
During the workshop you asked about qemu behavior once resuming a VM after EIO. I went back to check and qemu never passes the EIO to the guest, instead it retries the I/O. So it would seem that the current behavior should be fine (also with soft mounts).
Are there other error flows we should look into? I seem to recall we discussed other issues as well, but I don't remember the specifics (jet lag).
Regards, Ayal.
