Hi,
I started to learn the oVirt by following the oVirt Quick Start Guide.
I used one server as the ovirt.engine, and another server as the
ovirt.host. Both servers run Fedora 18.
After executing the command "engine-setup" in the ovirt.engine, I can
get into the admin portal to start the configuration of host, storage,
etc. Here was what I am doing:
1.In the Default data center, I clicked the Guide Me icon. The first
thing is to configure the host. After waiting for 4-5 minutes, I saw
the host ovirt.host is displayed under the Host tab with the Up status.
2.On the ovirt.engine server, I did the following before creating the
storage:
mkdir --p /mnt/data
chown --R 36:36 /mnt/data
Add the following line to /etc/sysconfig/nfs:
NFS4_SUPPORT="no"
Add the following line to /etc/exports:
/nmt/data *(rw,sync,no_subtree_check,all_squash,anonuid=36,anongid=36)
systemctl restart nfs-server.service
3.Back to the Default data center, clicked the Guide Me icon to start
the configuration of new storage.
4.On the New Storage dialog, set Name field to be NFS-Share, and set
the Export Path field to be ovirt.engine:/mnt/data. Then click OK
Can you select ovirt.host behind 'User Host' label ?
As I mentioned in pre-email, you should add your ovirt-engine host as
ovirt-node and up it, maybe you can select ovirt.engine
Here, ovirt-engine browser showing dialog box, 'Use Host' and 'Export
Path' they are should be matched.
Thanks.
After couple of minutes, I saw the error window popped up: Error:
Cannot add Storage. Internal error, Storage Connection doesn't exist.
From the /var/log/ ovirt-engine/engine.log, I can see:

Please let me know what I was doing wrong.
Thanks,
Hongyi
P.S. If I create the NFS domain in the ovirt.host side (i.e., Export
Path is ovirt.host:/mnt/data), then everything is okay. Not sure why
failed on the ovirt.engine side.
