I'm using oVirt on a OVH's dedicated server. The bare metal works as host and 
the engine is installed on a OVH's public cloud VM. I've also nested three 
other oVirts inside the host.
Maybe i could help you , what's your issue? I'd put my money on OVH network 
configuration :)

In 4.2 we have a better OVN support which should definitively help there.
Why not write and share a small blog post with your oVirt on OVH hints?

I'd be glad to do it!
Maybe i'll be able to use some spare time during the holydays.

Interesting. Maybe I don't understand it because I'm a newbie but...what's the 
meaning of a replica 1 solution? I mean, if i have only one host where's the 
replica?

Of course no replica with replica 1, but you could start like that then add 
other 2 hosts in the future and gain replica 3 just with a little 
reconfiguration and probably also without any downtime.

So it should be again possible to use just a single host for
everything, I am not sure we have a documentation ready for that
though.

Hi,

one of the new features of oVirt 4.2 is support for Replica 1 all in
one setup using hosted engine and gluster in hyper-converged mode.

So it should be again possible to use just a single host for
everything, I am not sure we have a documentation ready for that
though.

You could install Engine on a machine and re-use the same machine and
install it as a hypervisor. Apart from minor conflict between firewall
configurations, it should work.
See http://blog.domb.net/?p=2141 for such setup.

We don't have anymore an all-in-one installation where the engine and vdsm
runs altogether in the same machine; the proposed replacement is
hosted-engine which doesn't work with local storage since it's supposed to
be able to restart the engine VM somewhere else for HA reasons and the
local storage is against that by definition.
If you have three machines I'd suggest an hyperconverged gluster deployment
with replica 3.

If you want to try it on a single machine keep present that NFS in
loop-back is discouraged so maybe you could try iSCSI or, maybe with a
small hack, gluster in replica 1 in loopback

Hi,

if you bought a dedicated server with virtualization extensions
enabled you should have no problems.

Ask your provider if that extension is enabled. A friend of mine on
hetzner is using KVM without issues, but required some tweaks about
network that you can find in their docs.
