clh: Failing on new k8s test "OOM events for pods" for cloud-hypervisor in kata 2.0

[likebreath]

As a part of fixing the regression of clh CI for kata 2.0 (PR #2862), the failure on test OOM events for pods is observed (as reported in here):

22:21:16 1..1
22:21:48 not ok 1 Test OOM events for pods
22:21:48 # (in test file k8s-oom.bats, line 30)
22:21:48 #   `kubectl wait --for=condition=Ready pod "$pod_name"' failed
22:21:48 # INFO: k8s configured to use runtimeclass
22:21:48 # pod/pod-oom created
22:21:48 # error: timed out waiting for the condition on pods/pod-oom
22:21:48 # pod "pod-oom" deleted
22:21:48 Failed at 80: bats "${K8S_TEST_ENTRY}"
22:21:48 [reset] Reading configuration from the cluster...
22:21:48 [reset] FYI: You can look at this config file with 'kubectl -n kube-system get cm kubeadm-config -oyaml'

As this is a new test (added today #2854), it is advisable to debug on this in a separate PR, after bring CLH CI back online.

I've seen this happening on debian, and CentOS as well.

Closing this issue as it has been solved by https://github.com/kata-containers/tests/pull/3499/files

@GabyCT, sorry for re-opening this one, but I think we should only close this after re-enabling the test on clh:

tests/integration/kubernetes/run_kubernetes_tests.sh

Lines 56 to 64 in 899576a

	if [ "${KATA_HYPERVISOR:-}" == "cloud-hypervisor" ]; then
	sysctl_issue="https://github.com/kata-containers/tests/issues/2324"
	info "$KATA_HYPERVISOR sysctl is failing:"
	info "sysctls: ${sysctl_issue}"
	oom_issue="https://github.com/kata-containers/tests/issues/2864"
	info "$KATA_HYPERVISOR is failing on:"
	info "pod oom: ${oom_issue}"
	else

I've opened #3574 to check that.
