I have an ovirt installation (4.2.6), and I have come accross this issue:
Hosted engine can migrate to a certain host say host5. Admin portal is working fine, everything is working fine AFAIK but hosted-engne --vm-status shows "failed livelines check", when engine is on that host, so after a while the engine migrates somewhere else, it not a terrible problem, but it is annoying and I would like to know why is this happening, and if there is a way to fix it
On every other host in the cluster this problem does not exists. firewall rules are exactly the same on hosts (in fact they are copied) . Any places to look at?

Liveliness check is performed over http so I'd suggest to check whatever on the host could cause it to fail like routing rules and name resolution for the engine VM and so on.

You can try to manually reproduce the check executing:

. /etc/ovirt-hosted-engine/hosted-engine.conf

curl http://${fqdn}/ovirt-engine/services/health

Thank you
