<br>
Okay, I'm again having problems with getting basic networking setup with oVirt 4.1 Here is my situation. I have two servers I want to use to create an oVirt cluster, with two different networks. My "public" network is a 1G link on device em1 connected to my Internet feed, and my "storage" network is a 10G link connected on device p5p1 to my file server. Since I need to connect to my storage network in order to do the install, I selected p5p1 has the ovirtmgmt interface when installing the hosted engine. That worked fine, I got everything installed, so I used some ssh-proxy magic to connect to the web console and completed the install (setup a Storage domain and create a new network vmNet for VM networking and added em1 to it.)<br>
<br>
The problem was that when I added a second network device to the HostedEngine VM (so that I can connect to it from my public network) it would intermittently go down. I did some digging and found some IPV6 errors in the dmesg (IPv6: eth1: IPv6 duplicate address 2001:410:e000:902:21a:4aff:fe1<wbr>6:151 detected!) so I disabled IPv6 on both eth0 and eth1 in the HostedEngine and rebooted it. The problem is that when I restarted the VM, the eth1 device was missing.<br>
<br>
So, my question is: Can I add a second NIC to the HostedEngine VM and make it stick, or will it be deleted whenever the engine VM is restarted? </blockquote></div></div></div></div></blockquote><div><br></div><div>When you change something in the HE Vm using the web ui, it has to be saved also on the OVF_STORE to make it permanent for further reboot.</div><div>Martin can you please elaborate here?</div><div><br></div><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Is there a better way to do what I'm trying to do, ie, should I setup ovirtmgmt on the public em1 interface, and then create the "storage" network after the fact for connecting to the datastores and such. Is that even possible, or required? I was thinking that it would be better for migrations and other management functions to happen on the faster 10G network, but if the HostedEngine doesn't need to be able to connect to the storage network maybe it's not worth the effort?<br>
<br>
Eventually I want to setup LACP on the storage network, but I had to wipe the servers and reinstall from scratch the last time I tried to set that up. I was thinking that it was because I setup the bonding before installing oVirt, so I didn't do that this time.<br>
<br>
Here are my /etc/sysconfig/network-scripts<wbr>/ifcfg-* files in case I did something wrong there (I'm more familiar with Debian/Ubuntu network setup than CentOS)<br>
