[ovirt-users] Re: nul interface error when engine is creating ovirtmgmt bridge post-deployment
For those that may come across this thread with the same issues ive been encountering, I found a workaround to my related NAT issue (use at your own risk). 1. I included the setup of the bridge in the ovirt kickstart, due to the differences in hardware ill be dealing with I turned off Consistent Naming. 2. I have a custom process that re-enables the ovirtmgmt bridge using the API. I haven't confirmed if step one is required, theoretically you could wait until the host is put into non-operational mode, list out the host and grab the interface marked as "up" (that is, if your setup is simple like mine where we only use one port AND it has established the interface listing, I honestly don't think it does until its online the first time, TBD.). Then you can plug the primary interface in to the host_service.setup_networks() function (python sdk) and it would create the bridge. For my process I wait until the api reports the interfaces available on the unit, taking the one that's up and passing it along to my setup functions which rebuilds the ovirtmgmt bridge per ovirt's specs. 3. Lastly I run through each of the networks assigned to the cluster and add them through the api, I assumed that they wouldn't be added automatically after the host gets marked as non-operational so I force the addition via api. Hope that helps. -Brad ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/HUCPY5QOYC4VQIA4NPULXMLCSOAGZBM2/

Hah.. Confirmed what I figured, thank you. I'll chalk it up to a bug(?) that i can get the network working if I use the GUI, in the future if something goes sideways i'll start with it being behind a NAT, first.

Based on your last comment in the response i'll bet that being behind the nat answers my issue in general. Supplying the logs anyway for sanity but i'm betting that because i'm initiating the update of the logical networks from the GUI it takes a different approach to push down the changes than the initial setup? The more I think about it the less sense it makes since it SHOULD use the same delivery methods, no? And before anyone calls me ridiculous for having this connectivity go through a nat on both sides, I know, I inherited the methodology and am trying to work within confines that I am allowed. Anywho, here goes, thanks for the reply appreciate the feedback GREATLY. ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/JODZ7JJUOGMRNLRH3BDJBKIQUDP3EEPA/

For some reason oVirt does not detect the NIC or birdge which has the expected IP address. Is there an physical interface on the host with the IP address used to add the host to oVirt?
