Trouble in switch type to OVS process

Adding some relevant people 2018-01-15 23:13 GMT+01:00 Dmitry Semenov <zend0@ya.ru>:
Hi everyone!
I have installed oVirt ver 4.2 on three nodes with shared storage (FC) and linux bridge setting: - node01
- node02 (self-hosted Engine host)
- node03 (self-hosted Engine host)
I wanted to set cluster network switch type to OVS (for OVN)
(followed this instruction *https://ovirt.org/develop/release-management/features/network/provider-physi... <https://ovirt.org/develop/release-management/features/network/provider-physical-network/> )
After this step “*Set OVS networking on all vdsm hosts.* For each host, enable Maintenance mode, Sync All Networks” - my node01 disappeared. I don’t know what to do further.
For the rest 2 nodes (node02 and node03) i didn’t check this step.
Each node has bond (from 2 NIC), and each bond has configuration with 3 VLANS for: ovirtmgmt, migration, display.
How can I return node01 to cluster with OVS and switch other nodes to OVS?
Best regards,

Please note that OVN overlays work just fine with Linux Bridge switchtype. You need to move to OVS only if you want OVN on non-overlays.
After this step “*Set OVS networking on all vdsm hosts.* For each host, enable Maintenance mode, Sync All Networks” - my node01 disappeared. I don’t know what to do further.
In "disappeared" do you mean it became non-responsive? Would you share with us your supervdsm.log from the disappearing host? For the rest 2 nodes (node02 and node03) i didn’t check this step.

Dan, if I catch you right, I dont need to switch to OVS for creation of internal networks with DHCP (for vms) and their routing to external networks. Thats true?

After launch of network synchronization all settings of ovirtmgmt interface disappeared on node, after that node became unavailable. supervdsm.log: https://pastebin.com/eW0UpB6j

Yes. You can use default Linux bridge networks. Create an OVN overlay network with subnet for VMs. Then create a "router" VM that is connected to both overlay and a physical network, configure routing there.
After this step “Set OVS networking on all vdsm hosts. For each host, enable Maintenance mode, Sync All Networks” - my node01 disappeared. I don’t know what to do further.

Thanks, will take a look.

Dmitry, could you please share you vdsm.log and engine.log as well? Thanks, Petr 2018-01-16 12:22 GMT+01:00 Petr Horacek <phoracek@redhat.com>:
