Comment 11 for bug 1297218

A few notes after a few weeks of playing with this.

I've not reproduced the failure with migration per se.

However, when I did not add 'aio=native' to the backing store flags (i.e. file=/mnt/disk.img,if=virtio,cache=none,aio=native), after around 2 days qemu would exit saying

 (qemu) qemu: qemu_thread_create: Resource temporarily unavailable

This appears to me to be a bug in the underlying gluster mount.

Until it is verified that this can be reproduced with another shared backing store and is not simply a result of bad behavior of the underlying glusterfs, priority of this bug will be lowered.
