Hi Sahina,
I have checked the vdsm.log of the host and I can see the following:

Is there a way to fix this?

Also, when I try to reinstall one of the hosts (6 node cluster) it reinstalls 
just fine (except for host1) but does not deploy the engine capabilities to it.

thoughts?

thanks,

Adrian

[ovirt-users] Help/guidelines/ideas on how to create new hosted-engine on final server with old config

[Lars Bækmark]

I'm looking for guidelines/ideas for moving/migrating/Hosted-engine from the 
initial install with local storage, to the "Final" server.
Initial it was a "Test" to see if this will work or not, but this has now 
become the production, where the initial host named "ovirt" that is hosting the 
hosted-engine on local storage is "just" doing that. My hosted-engine is called 
"ovirtmgr" and I created a new host to run Virtual machines called "Hermod" - 
getting better in the naming thing, right? This test was so successful that I 
converted the old Xen/Oracle based host to CentOS 7 - the same as host Ovirt 
and Hermod:
Linux hermod 3.10.0-1062.1.1.el7.x86_64 #1 SMP Fri Sep 13 22:55:44 UTC 2019 
x86_64 x86_64 x86_64 GNU/Linux 

Linux fernis 3.10.0-1062.el7.x86_64 #1 SMP Wed Aug 7 18:08:02 UTC 2019 x86_64 
x86_64 x86_64 GNU/Linux 
oVirt version is: 4.3.5.4-1.el7
I want to move the hosted-engine to Fenris and at the same time use a NFS share 
for that. I can shut the whole setup down, as long as it runs again in daytime.
I do know that I should have started with the hosted-engine in the correct 
place, but that's not the case anymore. There are eleven VM’s in total 
Can anyone suggest a plan on how to move/create a new hosted-engine on my 
server Fenris? The history of the old server is not important, I just want the 
hosted-engine on fenris using NFS share
I did find some sugesting on the web, but they all look quite complicated: 
https://www.ovirt.org/…/engine/migrate-to-hosted-engine.html 

I just love the product! I'm now running VM's 2-3 times faster by converting 
from Xen to KVM, but still use the same storage and server! :-D
Appreciate any help! 😀

[ovirt-users]Re: Can ovirt-node support multiple network cards ？

[jeremy_tourville]

I am unable to tell from your question what research you have done or what you 
have tried so far.  Anyway, review this- 
https://ovirt.org/documentation/admin-guide/chap-Logical_Networks.html.  
Generally speaking, the checkbox for "Connect to physical network" should not 
be needed for your example.  You most likely will need to set up VLANs when you 
create the logical network.
