Comment 5 for bug 1970679

So with extra logs got a failure[1]:-

As per it it took more than 5 seconds to start[2], and generally it's too quick:-

May 23 08:16:48 nested-virt-ubuntu-focal-ovh-bhs1-0029738346 systemd[1]: Started Open vSwitch database server for OVN Northbound database.

So we can double the retries to 10 to be more on safe side for this. With this also noticed https://review.opendev.org/c/openstack/neutron-tempest-plugin/+/836912 switched these jobs to deploy from ovs/ovn from source unintentionally and those jobs are not impacted by this issue.
