Re: [ovirt-users] EXTNET Hook and Libvirtd Default Network Setup
Hi Andrew, In the medium term I think that might be easier and more scalable - oVirt should allow you to not have to deal with libvirt plumbing. Re-reading your original e-mail, I only now understand that you're using the default network to setup NAT, and that you weren't adding iptables rules on your own. If you do prefer to go with that, I have very little knowledge of libvirt's NAT. Maybe others on the list know more... Yours, Lior.

Medium-term, my plan is to spin up another VLAN and routable private subnet with DHCP to trunk our virtualization hosts onto. That requires more people to get involved to get the testing environment in place. I suppose I can spin up a DHCP server and private network outside of libvirt on the machine itself and add to oVirt.

For their testing, they want to use the default NAT'd network from libvirtd on the host. I've install oVirt, installed the extnet hook, enabled IP forwarding in sysctl.conf and loaded the setting, and created a vm that attaches to the libvirtd default network and gets an IP. The VM can ssh to the virbr0 IP address, in this case 192.168.122.1, to access the host. However, the VM cannot reach any IP address off of the NAT'd subnet. I haven't changed any of the default iptables rules that oVirt and libvirtd create. Looking at ip route and the iptables rules, I feel that traffic should be getting directed appropriately. Could you elaborate why there's need to meddle with the networking at the level of libvirt and to use the extnet hook? If all you need is an IP address and NAT, I would think a default oVirt setup would do as long as you have a DHCP server and add proper iptables rules to the host. Even if you do in fact need the specific libvirt network and to use the hook, maybe it's worth trying without them first - just to make sure your iptables rules are alright (they would be my prime suspect). Does anyone have any thoughts as to what the issue may be? For some reason, the ovirtmgmt bridge doesn't seem to be receiving or allowing traffic from virbr0 to pass across it. I can provide more information if that would be helpful!

That's a new 3.5 feature. Mind you yii must first upgrade the storage domain to 3.5 before reinstalling Thanks for the tip. This didn't work for me this time. My AIO setup started out with 3.2, upgraded all the way up to 3.5, I was missing the OVF files, so I couldn't import the storage domain. So I bit the bullet one more time and did it the hard way (created new VMs, disks, then copied over the old image). This time I created a storage domain for each VM so I can import them into a new setup individually. Creating storage domain per vm is not a good idea. The system is expecting all storage domain to be accessible by all hosts. So if you have multiple storage domains and one become inaccessible, a host may become non-operational, which will cause migration storm from this host to other hosts. Basically, the more storage domains you have, your system is more fragile. Create new storage domains only when you must (e.g. separating testing and production environments). For importing and exporting vms, you can use the export domain. Nir ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

It works now with my native client. Some strange.. The oVirt websocket proxy is part of the engine and it's by default installed on the engine host when you install the engine; engine-setup asks if you want to configure it or not. Than, if you really need for your network design, you can also install and configure the websocket proxy on a different host. http://www.ovirt.org/Features/WebSocketProxy_on_a_separate_host but this is already a special case. I read in this thread that you are using centos7 (also for the engine host?). We didn't release oVirt 3.5.0 for el7 but we'll do since 3.5.1 which is targeted just after Christmas vacation (you are welcome to help us testing it on centos7!) so now you still cannot find ovirt-websocket-proxy rpm for el7 on the stable branch.
