[ovirt-users] self-hosted-engine Failed to establish session with host

[Neil]

Sorry to be replying to my own post, but I'm not sure if by adding the Host
manually that I've perhaps messed up something now?

How do I go about adding my default NFS storage domain because no storage
domain exists currently despite my hosted_engine being a VM already running
on my default domain? In fact when I look at my hosted_engine and go to
disks it shows there is no disk at all.

Thanks!

Regards.

Neil Wilson.
