Hi Sandro,
I do see: # cat /etc/selinux/targeted/modules/active/file_contexts.local # This file is auto-generated by libsemanage # Do not edit directly. /mnt/iso(/.*)? system_u:object_r:public_content_rw_t:s0 /mnt/data(/.*)? system_u:object_r:public_content_rw_t:s0
On wich host? It's failing creating domain on 128.224.147.229:/mnt/data. You must be sure that the IP address is correct. You need to be sure that on 128.224.147.229 /mnt/data is 775, owned by 36:36, and selinux allow public content. Then you need to be sure that you can mount 128.224.147.229:/mnt/data locally. On the host running engine try: mkdir /tmp/test mount -t nfs 128.224.147.229:/mnt/data /tmp/test Then if it works you must ensure it's writable by vdsm:kvm user: sudo -u vdsm -g kvm mkdir /tmp/test/writable sudo -u vdsm -g kvm touch /tmp/test/writable/file If those commands are working, you should be able to create the domain. Remember to cleanup after the test.
# getenforce Permissive
But I still failed to create a storage domain on the ovirt.engine side and got the same exception errors, and also vdsm is idle during the creation of storage domain.
Here is the setup for ovirt.engine: oVirt Engine will be installed using the following configuration: ================================================================= override-httpd-config: yes http-port: 80 https-port: 443 host-fqdn: ovirt.engine auth-pass: ******** org-name: ovirt application-mode: both default-dc-type: NFS db-remote-install: local db-local-pass: ******** nfs-mp: /mnt/iso config-nfs: yes override-firewall: IPTables Proceed with the configuration listed above? (yes|no): yes
Thanks, Hongyi

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
Well, exports has a typo error: /nmt/data instead of /mnt/data If that it's not enough, If you're using selinux ensure that /mnt/data has the correct context:
/etc/selinux/targeted/modules/active/file_contexts.local: /mnt/data(/.*)? system_u:object_r:public_content_rw_t:s0
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:
2013-07-10 11:37:51,300 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.ConnectStorageServerVDSComm and] (ajp--127.0.0.1-8702-1) [41c282da] FINISH, ConnectStorageServerVDSCommand, return: {00000000-0000-0000-0000-000000000000=100}, log id: 1bca7819

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.
