[ovirt-users] Re: Couldn't resolve host name for http://mirrorlist.centos.org/?release=8-stream&arch=x86_64&repo=storage-ceph-pacific

Hey there, I've been running into a really frustrating issue while trying to set up a self-hosted engine. I've tried multiple times, with different distributions like CentOS Stream 9, AlmaLinux 9.5, and Rocky Linux 9, but I keep hitting the same wall.   Essentially, during the engine configuration, I get an error saying that https://mirroros.centos.org is unreachable. I've tried all the repository workarounds I've seen online, changing the pointers and everything, but nothing seems to help.  The weird thing is, if I install the engine on a dedicated server, it works fine. It's only when I try to deploy a self-hosted engine that I get this mirror error. Then, just to see what would happen, I gave Oracle Linux a shot. And guess what?   The self-hosted engine configured perfectly, without even trying to touch those CentOS repositories.  So, that's definitely pointing to some kind of distribution-specific issue. On top of that, I've also run into another problem with the 4.5 distribution related to VLANs.  I'm working in a data center with a bunch of VLAN-certified networks.   I wanted to set up oVirt 4.5, using a self-hosted engine, and assign one of those VLAN networks to ovirtmgmt.   But the installation just flat-out fails because it only seems to accept physical network devices.   The only way I could get it to work was to put a switch in place to mask the VLAN, which is a bit of a clunky workaround.   My older 4.4-based virtualizer didn't have any of these problems, so I'm wondering if something's changed significantly in 4.5. Any ideas? Best regards On Sun, 2025-03-02 at 20:56 +0000, Geoff O'Callaghan wrote: --
