oVirt Single Server Install - Mgmt Network issues



  • Hi, wondering if anyone can shed some light on following,

    setting up oVirt on a fresh centos7 install, so far i've reached being able to login into the web portal and add my host in. After the initial host install, the status goes from up to non-operational after a couple secs - error on the i icon in the hosts view says no default route.

    In network setup, the management network "ovirtmgmt" keeps assigning itself to the next unused, disconnected interface on the pcie nic. Initially i only enabled the motherboard interface, then i enabled a single port on the pcie nic (the one it assigned itself initially), after second install it assigned itself to interface 2 on the nic which is disconnected and disabled.

    In web portal I've tried detaching ovirtmgmt and dragging it to the default interface but i lose connection to server when resyncing, also tried this with IF 1 on nic. I started over fresh about 4 times already while playing with the IF config files but no look so far.

    I'll post up IF configs later when i'm home, just after any pointers if anyone has come across this before?

    cheers.

    I dont' use oVirt. hopefully @stacksofplates sees this for you. I believe he deals with it.



  • Sadly I don't do anything with oVirt. I run OpenStack at home and bare KVM at work.

    SOrry, I thought you were doing oVirt stuff. my bad.



  • FYI

    Added MACADDR to both interfaces and set up configs before installing ovirt engine (again) - management network assigned to correct IF after installing host in web console, all sorted.



  • Eww ipv6 in use. Yea sorry I still haven't jumped on board with KVM and ovirt I'm still dirt at this time 😞

    No prob. I think @Tim_G was doing something with it. I just find it too bloated. It’s pretty sad whenever it’s easier to do an all in one OpenStack than it is to do oVirt.
