Works perfectly fine for me with VPN towards the environment.
I suppose you should use VPN level security for your connectivity to your data center resources.
Thanks in advance.
Best regards,
Nikolai

Hi,
As for me, I would build one cluster with gluster service only based on
two nodes (replica 2), and the other one with virt service only based on
other two nodes. I think this variant is more scalable in future.
PS. I am a new in oVirt, so do not except that I am wrong.

I have a dual host setup working right now. Host 1 runs the engine and
is also a node. Host 2 does DB storage and NFS storage. The WebSockets
proxy is running on Host1.
My question is how do I run this behind a router? I am correct in
understanding that the WebSockets proxy acts as the spice access point
for all of the nodes in the cluster / datacetner? or does each node host
need a direct connection for spice?
the .vv file I receive from the management console specifies the
engine's private IP address which works fine when inside the ovirt
management LAN, but it wont route from WAN obviously.
So essentially i guess i need squid to rewrite the served vv file to the
public IP and somehow make the ports work correctly, which is difficult
considering every time a VM is created it also adds its own spice port,
correct?

Dear all
I am not sure if the mail just did not get any attention between all the mails and this time it is also going to the libvirt mailing list.
I am experiencing a problem with VM becoming unresponsive when removing Snapshots (Live Merge) and i think there is a serious problem.
Here are the previous mails,
http://lists.ovirt.org/pipermail/users/2015-May/033083.html
The problem is on a system with everything on the latest version, CentOS 7.1 and ovirt 3.5.2.1 all upgrades applied.
This Problem did NOT exist before upgrading to CentOS 7.1 with an environment running ovirt 3.5.0 and 3.5.1 and Fedora 20 with the libvirt-preview repo activated.
I think this is a bug in libvirt, not ovirt itself, but i am not sure. The actual file throwing the exception is in VDSM (/usr/share/vdsm/virt/vm.py, line 697).
We are very willing to help, test and supply log files in anyway we can.
Regards
Soeren

Hi
For a production environment i would not build a 2 node gluster, i would build at least 3 nodes to have it much easier with the quorum.
Taking into account that you can use commodity hardware i would also suggest to split the services, but i would go for at least 3 gluster nodes ? which add up to at least 5 nodes for a HA system.
If you want 4 in any case, then my suggestion would be to go for 4 replicas, each node has anything that it needs to run and you can basically use NFS to localhost for the storage which would make the nodes always access the local storage for the VMS, availability wise it makes no difference.
Cheers
Soeren

Hello,
How to optimal configure 4 node cluster for any one node goes to maintenance without stopping VM ??
a) replica 4 - but it takes a lot of space
b) disperse 3+1 ( raid 5 ) - but bad performance and not visible by oVirt 3.7.2
c) stripe2+replica2 = but VM paused
any other idea ?

And sorry, another update, it does kill the VM partly, it was still pingable when i wrote the last mail, but no ssh and no spice console possible
