The oVirt Project is pleased to announce the availability
of the Third Release Candidate of oVirt 3.6.2 for testing, as of January 20th, 2016



Tested successfully on CentOS 7.2 with SH Engine on NFS and verified correct auto-import of SH Domain.
Hypervisor is a CentOS 7.2 VM inside Qemu/KVM in virt-manager (under my laptop that is Fedora 23).
So it is a nested virtualization environment.

Some NOTES
1) appliance
I see that the appliance rpm pulled in was
 ovirt-engine-appliance-3.6-20151216.1.el7.centos.noarch

I presumed it was not populated with correct rpms.
So in "hosted-engine --deploy" setup I used the appliance, but answered

Automatically execute engine-setup on the engine appliance on first boot (Yes, No)[Yes]? No

I then connect to the appliance OS and configure 3.6-pre repo and run 

yum update

Strange that this pulled in the package

ovirt-release36-003-1.noarch

and so the repo file was overwritten and was again 3.6 only and not 3.6-pre.
I re-modified /etc/yum.repos.d/ovirt-3.6.repo re-adding the pre.

and finally
engine-setup

and successfully completed the final part on host.

2) localtime on Engine was not asked but was set to UTC.
So
[root@shengine ~]# ln -sf /usr/share/zoneinfo/Europe/Rome /etc/localtime 

shutdown engine OS and after some minutes the VM came back online.

3) As this is a nested environment with NFS domain provided by the only host itself,
In /usr/lib/systemd/system/ovirt-ha-broker.service

Agdded in section [Unit]

After=nfs-server.service
So that I can manage shutdown/restart of host for complete maintenance operations

4) After adding first data domain, the hosted_storage storage domain came up automatically without any problem. Able to see engine vm in web admin portal and its disk and access its console (used vnc)
Also able to add ISO Domain.
(both data and iso are NFS on the host itself)
 
5) The only "problem" (?) I see is this message that I don't understand.
On hypervisors

6) ISO upload from engine by default doesn't work because its own host doesn't allow it
[root@shengine ~]# ovirt-iso-uploader -i ISO_DOMAIN upload /root/CentOS-7-x86_64-NetInstall-1511.iso 
Please provide the REST API password for the admin@internal oVirt Engine user (CTRL+D to abort): 
Uploading, please wait...
ERROR: mount.nfs: Connection timed out

If on host I run (.73 is IP of engine)
# iptables -I INPUT -s 192.168.122.73 -j ACCEPT

Then on engine:
[root@shengine ~]# ovirt-iso-uploader -i ISO_DOMAIN upload /root/CentOS-7-x86_64-NetInstall-1511.iso 
Please provide the REST API password for the admin@internal oVirt Engine user (CTRL+D to abort): 
Uploading, please wait...

7) Installed a CentOS 7.2 VM with netinst.iso. Access to spice console ok.
(85MB/s when downloading on nested network not so bad... ;-)

Very good starting point!
