Is it possible to setup a hosted engine using the OVS switch type instead of Legacy? If
it's not possible to start out as OVS, instructions for switching from Legacy to OVS
after the fact would be greatly appreciated.
Many thanks,
Devin

Just to close this thread, we were able to manually convert our hosted-engine 4.1.1
cluster from the Legacy to OVS switch types. Very roughly:
- Install first host and VM using "hosted-engine --deploy"
- In the Engine UI, change Cluster switch type from Legacy to OVS
- Shutdown the engine VM and stop vdsmd on the host.
- Manually change the switch type to ovs in
/var/lib/vdsm/persistence/netconf/nets/ovirtmgmt
- Restart the host
After that, everything seems to be working and new hosts are correctly setup with the OVS
switch type.
Thanks,
Devin

Hello Devin,
Thanks a lot for this. I was setting up a cluster and intended it enable OVN in it. I came
across this thread when searching for a solution.
Does this change in 4.3 version or 4.4 so we can specify switch type when creating a
self-hosted engine. Any ideas?

I tried this and it didn't work. In 4.3 the option to change the switch type is not
allowed. I still changed the switch type of ovirtmgmt in the file and rebooted. But it
didn't have any effect.
Isn't there a way we can specify OVS as switch type when installing the self-hosted
engine?

Hi,
yes 4.3 has the disabled the change of switch type, because it was broken
and only few scenarios succeeded. The 4.4 allows to change it after
installation.
For the second part @Asaf Rachmani <arachman(a)redhat.com> is there any
option in the HE deploy to specify default switch type? I am not aware of
anything like that.
Thank you.
Regards,
Ales

Hello
I need your advice, i have cluster with 3 nodes and iscsi common storage, with ovirt
version 4.4.10 i need change legacy to ovs switch.
I did configuration using instruction below:
- Install first host and VM using "hosted-engine --deploy"
- In the Engine UI, change Cluster switch type from Legacy to OVS
- Shutdown the engine VM and stop vdsmd on the host.
- Manually change the switch type to ovs in
/var/lib/vdsm/persistence/netconf/nets/ovirtmgmt
- Restart the host
After reboot, i coudn't start engine? because he couldn't find vnet and when i
changed back from ovs to legacy mode my hosted engine started without any problem
