Looking at the e2e.log file, it seems that the bootc container host name resolution is missing on the host where the tests are running.

$ grep 'no such host' e2e.log 
  I1226 10:03:04.073457 19 dump.go:124] Unable to retrieve kubelet pods for node microshift-okd-1: lookup microshift-okd-1: no such host
  I1226 10:22:59.120427 19 dump.go:124] Unable to retrieve kubelet pods for node microshift-okd-1: lookup microshift-okd-1: no such host
  I1226 10:53:09.606403 19 dump.go:124] Unable to retrieve kubelet pods for node microshift-okd-1: lookup microshift-okd-1: no such host

The easiest way to address this problem may be to add the container host name resolution to the /etc/hosts file where the tests are running.

$ sudo podman inspect microshift-okd-1 | jq -r .[].NetworkSettings.Networks[].IPAddress
10.89.0.11

$ sudo podman inspect microshift-okd-2 | jq -r .[].NetworkSettings.Networks[].IPAddress
10.89.0.12
