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
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.
