I decided to restart clean and in fact all went well.
Last lines of output of "hosted-engine --deploy"

engine is up and admin web portal accessible and host results up.

I expected storage to be configured inside admin web portal but apparently
I don't see anything already configured and also I don't see the sh engine
VM listed... is it correct?

Filesystem layout at this time on the hypervisor is this:
[root at ovc71 tmp]# df -h
Filesystem                           Size  Used Avail Use% Mounted on

/rhev/data-center/mnt/_var_lib_ovirt-hosted-engine-setup_tmpUEso__Q

BTW: what is the 2Gb file system on loop device?

I configured the storage domain part as NFS, pointing
to ovc71.localdomain.local:/NFS_DOMAIN
Reading page at
http://www.ovirt.org/Features/Self_Hosted_Engine

it is not clear to me what to do next if I want for example keep a single
host with its sh engine as a replacement concept of what before was
all-in-one... and start creating VMs....

Output of my web admin page:

Also, I didn't restart my hypervisor yet.
WHat should be the shutdown procedure? SImply run shutdown on hypervisor or
1) shutdwn engine vm
2) shutdown hypervisor
?
