Evaluate oVirt to remove VMware
Howdy All!!! Somewhat new user to Linux and having some issues with oVirt node networking. We are mainly a Windows/VMware medium shop but have a pretty good network. Our VMware setup has redundant switches using multiple VLANs. This was fairly easy to setup with VMware. We never had an issue with VMware, add 2 NICs to the ESXi host and then adding VLANs into the Virtual Switch. Biggest issue I am having, should I be bonding, teaming and VLANing on top of that? Tried setting up node with Engine inside which fails to deploy because of networking. Then I tried a standalone Engine and could not add node to it - I believe networking as well as Power Management agent was the problem. Would like the nodes/engine to be on one subnet (lets say 10.10.11.x) and VMs to be allowed to run there are well as 10 other VLANs. I guess welcome to the wonderful world of Linux networking and learning some new technologies is in store for me. I hope I am not being vague, like I said fairly new to Linux. Thanks for any responses! Allen
Hello Allen, In oVirt you can use VLANs and Bonds but not teaming. It may be useful to try a Centos(oVirt uses Centos or RHEL) install to see how the networking works, most notably you add devices that are VLANs or BONDs. I also check that the devices are enables on boot as I have been caught out with this which is especially annoying when doing remote installs. The power management uses other hosts as a proxy so you need at least 2 in a cluster but you can configure this later.

Thanks Paul, Hey Paul, Thanks for the reply! Not really sure here, I read the oVirt 3.0 pdf and it says you need to enable LACP for Cisco switches. This is really not becoming a learning setup any longer, just a headache. Tried multiple ways and still no luck... the next way I am trying is this: https://www.ovirt.org/develop/networking/bonding-vlan-bridge.html But not hoping any longer. Not sure if it will work or not, but going to give it a go. Thanks!!! Allen

Allen, please create bonds like described in https://www.ovirt.org/documentation/admin-guide/chap-Logical_Networks.html#c... avoid manual steps on the host. On Fri, Aug 23, 2019 at 11:37 AM Sandro Bonazzola <sbonazzo@redhat.com> wrote:

This is only required if you like to use bond mode 4, which is recommended if your switch supports this.

This guide should still work, but the configuration via Engine's Web UI or REST API is much more comfortable and safe.

Thanks Dominik, Went through this documentation earlier and it looked as if this was done after the Engine is installed. I am looking to get networking completely setup before the Engine so I have a template and can duplicate this effort across multiple hosts during install. Possibly using a kickstart script for hosts. FYI... I need to start with both NICs in a BOND as well as VLAN Tagging. Went through steps of "not your docs" that I mentioned earlier and I got much further. I was able to ping out, but the bridge was based off of br0 and not ovirtmgmt so I could not ping into or access the host remotely. For some reason the gateway never really mattered in the ifcfg scripts. I will thoroughly look at the doc again... but like I said I am trying to get this down to easily reproduce-able during install of OS. If we end up going with oVirt, it would be approx. a 100 Node install.
oVirt Masters! Got install of 2 nodes completed, but not it is giving errors I am not understanding... is this proxy errors or ??? I tested proxy settings with curl... not sure what else it could be.
