 Try a different (newer) ansible version.
+===== "msg": "MODULE FAILURE: No start of json char found\nSee stdout/stderr for the exact error" =====
+This is also possibly a mismatch with ansible versions and older python on target hosts. Try a different, older ansible version if running against older OS-es.
+===== couldn't resolve module/action 'community.libvirt.virt_install' =====
+You have the module installed but it still returns a similar error might be because of an older version of plugin. Run this to update it:
+  ansible-galaxy collection install community.libvirt -U
+Now 2 versions are shown, ansible should use the newest one.
+  ansible-galaxy collection list |grep virt
+  community.libvirt                        2.0.0
+  community.libvirt                        1.2.0
+Check also if the ansible version itself is compatible with plugin, on plugin document page.
+===== ansible-playbook hangs on specific server =====
+Check the ''ps'' output on the host where the ansible is being run from:
+  ps aux | grep ansible
+There should be an ssh command triggered where you should see the server hostname where the ansible is stuck on. Log into that server and check the ''ps'' again for any hanging processes.
