well, I ended in kind of loop. I have two hosts in HCI config with
glusterfs (I know that replica 2 is not supported, I will add third host
later). I migrated HE vm to other host, removed bricks on the first
host, removed the first host, hosted_engine_cleanuped it, yum removed
vdsm and all dependencies, nmcli con removed all interfaces
configuration, connect new cable to unused interface and configure ip
address from (ovirt)management vlan on it, rebooted.

Then I try to add this host to oVirt using that management ip address,
it worked but the network configurations now looks the same like before
removing of host (and I cannot form bond0 because oVirt thinks that
interface is already used and also I cannot move ovirtmgmt network to
mentioned dedicated interface because from ovirt's point of view ovirt
lost connectivity).

Doing stuff around ovirtmgmt is always tricky. About the point that oVirt thinks
that interface is used. Is it engine error or is it returned from vdsm?
 

Is it possible, that network configuration of removed host will survive
somewhere? On the host itself? (for example some vdsm configuration
which is not cleaned during uninstall?) Or in the engine database? (like
not all information about removed host is deleted during removing?)

Well the only location that comes to my mind related to the network configuration
is '/var/lib/vdsm/' specifically three folders 'persistence', 'staging', 'netconfback'.
The engine database is highly unlikely to store the configuration.
 

I am thinking how to workaround this issue without completely reinstall
HE and/or hosts (I can do it, at this point it is just lab installation
but it takes some effort and time...)
