with global maintenance enabled no such error is visible.

Ooops, this causes broken upgrade of SHE (engine) from 3.5 to 3.6:

3.5 engine obviously doesn't know this:

~~~
engine=# select version, option_name,option_value from vdc_options where option_name = 'HostedEngineVmName
';
 version | option_name | option_value 
---------+-------------+--------------

Steps:

1. have 3.5 SHE env
2. global maintenance
3. update rpms inside engine VM
4. engine-setup

Workaround:

curl -o /tmp/patch 'https://gerrit.ovirt.org/gitweb?p=ovirt-engine.git;a=patch;h=23e9a25de622eb374efa8ffcf8c0bb613082cfc5'
cd /usr/share/ovirt-engine
patch -p2 -R < /tmp/patch
