Hi, I am trying to deploy 3 hosts hyper converged setup. I am using Centos and installed KVM on all hosts. Host-1 Hostname - test1.localdomain eth0 - 192.168.100.15/24 GW - 192.168.100.1 Hoat-2 Hostname - test2.localdomain eth0 - 192.168.100.16/24 GW - 192.168.100.1 Host-3 Hostname - test3.localdomain eth0 - 192.168.100.16/24 GW - 192.168.100.1 I have created two gluster volume "engine" & "data" with replica 3. I have add fqdn entry in /etc/hosts for all host for DNS resolution. I want to deploy Ovirt engine self hosted OVA to manage all the hosts and production VM and my ovirt-engine VM should have HA enabled. I found multiple docs over internet to deply Self-hosted-engine-ova but I don't what kind of network configuration I've to do on Centos network card & KVM. As KVM docs suggest that I've to create a bridge network for Pnic to Vnic bridge. If I configure a bridge br0 for eth0 bridge that I can't see eth0 while deploying ovirt-engine setup at NIC card choice. Kindly help me to do correct configuration for Centos hosts, KVM & ovirt-engine-vm for HA enabled DC.

Interestingly enough I literally just went through this same thing with a slight variation. Note to the below: I am not sure if this would be considerd best practice or good for something long term support but I made due with what I had I had 10Gb cards for my storage network but no 10Gb switch, so I direct connected them with some fun routing and /etc/hosts settings. I also didnt want my storage network on a routed network (have firewalls in the way of VLANs) and I wanted the network separate from my ovirtmgmt - and, as I said, had no switches for 10Gb. Here is what you need at a bare minimum. Adapt / change it as you need 1 dedicated NIC on each node for ovirtmgmt. Ex: eth0 1 dedicated NIC to direct connect node 1 and node 2 - eth1 node1 1 dedicated NIC to direct connect node 1 and node 3 - eth2 node1 1 dedicated NIC to direct connect node 2 and node 1 - eth1 node2 1 dedicated NIC to direct connect node 2 and node 3 - eth2 node2 1 dedicated NIC to direct connect node 3 and node 1 - eth1 node3 1 dedicated NIC to direct connect node 3 and node 2 - eth2 node3 You'll need custom routes too: Route to node 3 from node 1 via eth2 Route to node 3 from node 2 via eth2 Route to node 2 from node 3 via eth2 Finally, entries in your /etc/hosts which match to your routes above Then, advisably, a dedicated NIC per box for VM network but you can leverage ovirtmgmt if you are just proofing this out At this point if you can reach all of your nodes via this direct connect IPs then you setup gluster as you normally would referencing your entries in /etc/hosts when you call "gluster volume create" In my setup, as I said, I had 2x 2 port PCIe 10Gb cards per server so I setup LACP as well as you can see below This is what my Frankenstein POC looked like: http://i.imgur.com/iURL9jv.png You can optionally choose to setup this network in ovirt as well (and add the NICs to each host) but dont configure it as a VM network. Then you can also, with some other minor tweaks, use these direct connects as migration networks rather than ovirtmgmt or VM network On Tue, Sep 12, 2017 at 9:12 AM, Tailor, Bharat < bharat@synergysystemsindia.com> wrote:

Hi Charles, Thank you so much to share a cool stuff with us. My doubts are still not cleared. 1. What If I have only single Physical network adaptor? Can't I use it for management network & production network both. 2. If I have two Physical network adaptor, Can I configure NIC teaming as like Vmware ESXi. 3. What If my ovirt machine fails during production period? In vmware we can access ESXi hosts and VM without Vcenter and do all the stuffs. Can we do the same with Ovirt & KVM. 4. To deploy ovirt engine VM, what kind of configuration I'll have to do on network adaptors? (eg. just configure IP on physical network or have to create br0 for it.) 5. Can I make multiple VM networks for vlan configuration?

1. Yes, you can do this 2. Yes, In linux it's called bonding and this can be done from the UI 3. You can get around using the Engine machine if required with virsh or virt-manager - however I would just wait for the manager to migrate and start on another host in the cluster 4. The deployment will take care of everything for you. You just need an IP 5. Yes, you can use vlans or virtual networking(NSXish) called OVS in oVirt. I noticed on your deployment machines 2 and 3 have the same IP. Might want to fix that before deploying Happy trails ~D On Tue, Sep 12, 2017 at 2:00 PM, Tailor, Bharat < bharat@synergysystemsindia.com> wrote:

Bharat - 1. Yes. Will need to configure switch port as a trunk and setup your VLANs and VLAN ID's 2. Yes 3. You can still access the hosts. The engine itself crashing or being down wont stop your VMs or hosts or anything (unless fencing). You can use virsh 4. My suggestion here is start immediately after a fresh server install and yum update. Installer does a lot and checks a lot and wont like things: ex - you setup ovirtmgmt bridged network yourself 5. Yes. See #1, usually what I do is each ovirt node I have I set an IP of .5, then .6, and so on. This way I can be sure my network itself is working before adding a VM and attaching that NIC to it On Tue, Sep 12, 2017 at 4:41 PM, Donny Davis <donny@fortnebula.com> wrote:

@Donny my 3rd node's IP is 192.168.100.17(Mentioned wrong in above mail). I was trying to install ovirt ova on test2.localdomain. I've cleared all the steps and at last I got a message like "Engine is still unreachable". Kindly help me to troubleshoot it.
@Ykaul How can I register myself in mailing list?

Hi Charles,
Thank you so much to share a cool stuff with us.
My doubts are still not cleared.
1. What If I have only single Physical network adaptor? Can't I use it for management network & production network both. 2. If I have two Physical network adaptor, Can I configure NIC teaming as like Vmware ESXi. 3. What If my ovirt machine fails during production period? In vmware we can access ESXi hosts and VM without Vcenter and do all the stuffs. Can we do the same with Ovirt & KVM. 4. To deploy ovirt engine VM, what kind of configuration I'll have to do on network adaptors? (eg. just configure IP on physical network or have to create br0 for it.) 5. Can I make multiple VM networks for vlan configuration?

You'll need custom routes too:
Route to node 3 from node 1 via eth2 Route to node 3 from node 2 via eth2 Route to node 2 from node 3 via eth2
Finally, entries in your /etc/hosts which match to your routes above
Then, advisably, a dedicated NIC per box for VM network but you can leverage ovirtmgmt if you are just proofing this out
At this point if you can reach all of your nodes via this direct connect IPs then you setup gluster as you normally would referencing your entries in /etc/hosts when you call "gluster volume create"
In my setup, as I said, I had 2x 2 port PCIe 10Gb cards per server so I setup LACP as well as you can see below
This is what my Frankenstein POC looked like: http://i.imgur.com/iURL9 jv.png
You can optionally choose to setup this network in ovirt as well (and add the NICs to each host) but dont configure it as a VM network. Then you can also, with some other minor tweaks, use these direct connects as migration networks rather than ovirtmgmt or VM network

Hi,

I have created two gluster volume "engine" & "data" with replica 3. I have add fqdn entry in /etc/hosts for all host for DNS resolution.
I want to deploy Ovirt engine self hosted OVA to manage all the hosts and production VM and my ovirt-engine VM should have HA enabled.
I found multiple docs over internet to deply Self-hosted-engine-ova but I don't what kind of network configuration I've to do on Centos network card & KVM. As KVM docs suggest that I've to create a bridge network for Pnic to Vnic bridge. If I configure a bridge br0 for eth0 bridge that I can't see eth0 while deploying ovirt-engine setup at NIC card choice.
Kindly help me to do correct configuration for Centos hosts, KVM & ovirt-engine-vm for HA enabled DC. Regrards Bharat Kumar

Hi, I've reinstall Centos7 Minimal on all three hosts. Installed Ovirt self hosted ova 4.1 on test1.localdomain. After installation completed, I got an error like engine vm is unreachable. I am able to ping engine from both IP and FQDN but unable to access it in browser. When I check engine VM status I got an error "Failed to connect to broker". I've enclosed engine-vm config snap and Error snap for more details. Kind help to resolve it.

Hi, I've reinstalled Centos minimal on 3 hosts. Configured replica 3 gluster storage for engine & data. Configured dns entry in /etc/hosts for all three host and ovirt engine also. *yum install ovirt-engine-appliance* *hosted-engine --deploy* Choose glusterfs storage for engine. Installation failed at last step "This system is not reliable". My host have low memory & processor so don't know it might be the issue. Please help.

Hi,
I've reinstall Centos7 Minimal on all three hosts. Installed Ovirt self hosted ova 4.1 on test1.localdomain. After installation completed, I got an error like engine vm is unreachable. I am able to ping engine from both IP and FQDN but unable to access it in browser. When I check engine VM status I got an error "Failed to connect to broker". I've enclosed engine-vm config snap and Error snap for more details. Kind help to resolve it.

Bharat,
Are you using DNS for host names or /etc/hosts
I personally place the engines hostname with ip address in /etc/hosts on all the hypervisors in case my DNS services go down. I also put the hypervisors in /etc/hosts too
Hope this helps.
