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 i=
nto 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 firs=
t 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 th=
e storage:
mkdir -p /mnt/data
chown -R 36:36 /mnt/data
Add the following line to /etc/sysconfig/nfs:
NFS4_SUPPORT=3D"no"
Add the following line to /etc/exports:
/nmt/data *(rw,sync,no_subtree_check,all_squash,anonuid=3D36,anongid=3D=
36)
systemctl restart nfs-server.service
3. Back to the Default data center, clicked the Guide Me icon to star=
t 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 ad=
d Storage. Internal error, Storage Connection doesn't exist.

P.S. If I create the NFS domain in the ovirt.host side (i.e., Export Path i=
s ovirt.host:/mnt/data), then everything is okay. Not sure why failed on th=
e ovirt.engine side.
