[ovirt-users] Cannot prepare internal mirrorlist: Curl error (6): Couldn't resolve host name for http://mirrorlist.centos.org/?release=8-stream&arch=x86_64&repo=virt-ovirt-45 [Could not resolve host: mirrorlist.centos.org]

I am in the Prepare VM step in ovirt installation. and I keep getting the above error. Why is the unused repo address defined even though I downloaded the latest ovirt-node? Where can I find repo addresses for el8 that can be accessed for installation? Is ovirt a discontinued system?
