[Users] NIC problem with ovirt node
I've just installed my first ovirt node using the 2.6.1 image. I have 5 network interfaces in the machine .. ovirt sees them as: em1, em2, em3, em4, and rename6! That last one seems a little odd, but that's a different issue, I guess. From dmesg..
[ 4.650156] systemd-udevd[213]: renamed network interface eth2 to em4 [ 4.656189] systemd-udevd[212]: renamed network interface eth0 to em3 [ 4.662193] systemd-udevd[209]: renamed network interface eth1 to em2 [ 4.670385] systemd-udevd[214]: Tried to rename network interface eth3, but the target name em2 already exists! The names that udev rules assign to network interfaces must be changed. Avoid names that collide with kernel created ones. A workaround will be attempted now, but this WILL BREAK in a future release! See https://bugs.freedesktop.org/show_bug.cgi?id=56929#c3 [ 4.675179] systemd-udevd[214]: renamed network interface eth3 to rename6
What IS a big deal is that every time I configure one network interface, the others go back to "unconfigured". I'm told this is because I should only configure one on the ovirt-node, and then use the engine to configure the rest. Okay -- does it say that somewhere that I missed? :) but when I'm in the engine, I can click on the node, and see that it's up. I can click on network interfaces, and see that one is up, and the other are down. I can create networks on the engine, and I can assign the nodes interfaces to those networks, but for the life of me, I can't figure out where I assign an IP to the nodes interfaces!! Surely, the place to do that would be under the "Host" tab, yet it doesn't seem to be there... Any help would be much appreciated. Jason.

There should be a warning that configuring a new nic will disable previously configured nics.

Host Tab -> Network Interfaces -> click on Setup Host Networks On the popup, hover over the logical network (not the nic) and a little pencil or pen (or some other graphic) that is used for editing. Click on that and you'll get another popup where you can choose static/dhcp and set gateway, ip and netmask. Mike
Any help would be much appreciated.

Nope.. no warning whatsoever...

Thank you *so* much! I did not see the little pencil!!! Jason.

Ah, bad memory on my part. It was there in an older release, but the one you're running had a new UI framework and this was missed. It's definitely something we will be adding back.

Actually, Mike -- two of my networks were private and didn't need a gateway... but two are public, and need a gateway! Unfortunately, the interface seems to be missing that option!? It lets you configure an IP, and a subnet mask, but where's the option for specifying a gateway if you're specifying static addresses... (my guess is that it picks up the gateway if you're using DHCP). Jason.

please open a bug to improve the usability if you couldn't see it...

multiple gateways? something like this? http://www.ovirt.org/Features/Multiple_Gateways

I will do this.

Yes. Sort of -- simpler actually. I have 4 network interfaces in each node. My "management" network consists of a 1 Gbit switch connected to all the servers in our machine room. Here, I don't need to specify a gateway since servers on this network talk to only each other. Actually, I'm surprised I can't rename ovirtmgmt to something else to generalize it as just a "management network", but it's not a big deal, I guess. My "Storage" network consists of a 1 Gbit switch now - 10 Gbit soon. Again, I don't need to specify a gateway here. Finally, the last 2 NICs are connected to the external network - a building switch that another Department controls. Here, I definately need to specify a gateway, but of course with the current setup, I can't. I will either have to hard code the gateway for these connections, or use DHCP. Since there is only one "gateway" for the external connectivity, all on the same VLAN, I don't think I need the more complicated iproute2 setup here. I prefer to stay away from that if I can... I'm surprised this isn't a more common configuration. Jason.

Hello, bu here in my opinion are mixing different things. What Itamar indicated aims to address problems related to spice (aka display) networks and ovirtmgmt network when they are different in routing and currently the only gw for the host is on the ovirtmgmt one. When we are talking about VM networks in my opinion the gateway settings has to be delegated at VM level not host level. Host needs only to have physical connectivity. Am I wrong? For example in VMware if I configure a standard virtual switch and then define a port group/ VM network on it, I only specify an optional VLAN ID for this network and some policies for security, nic teaming and traffic shaping.. no gateways at all. And for its network adapters I configure speed, duplex Gianluca
