You can ignore this warning for now and get to it later on.

Now is the time to explain something.

ovirt-host-deploy is not designed to be ran manually like you try.

You will get the exact same error if you try to do this on CentOS or Fedora.

The normal way it works is that the engine "bundles" it in a tarball,
copies it to the target host using ssh, untars it there and runs it.

It then talks with it - the engine sends some stuff, host-deploy replies, etc.

The protocol they use is described in otopi, in the file README.dialog.

otopi has (currently) two "dialects" - "human" (default) and "machine".
The engine and ovirt-host-deploy talk using the machine dialog.

To make ovirt-host-deploy talk with you using the machine dialog,
you should run it with:

ovirt-host-deploy DIALOG/dialect=str:machine

To make it let you configure it, run it with:

ovirt-host-deploy DIALOG/dialect=str:machine DIALOG/customization=bool:True

To know what it expects at each stage, I suggest to have a look at an
ovirt-host-deploy log generated on el7 or fedora.

Anyway, congrats for a nice progress!

If you check such a log file, you'll see there (among other things):

DIALOG:SEND       **%QStart: CUSTOMIZATION_COMMAND
DIALOG:SEND       ###
DIALOG:SEND       ### Customization phase, use 'install' to proceed
DIALOG:SEND       ### COMMAND>
DIALOG:SEND       **%QHidden: FALSE
DIALOG:SEND       ***Q:STRING CUSTOMIZATION_COMMAND
DIALOG:SEND       **%QEnd: CUSTOMIZATION_COMMAND
DIALOG:RECEIVE    env-query -k VIRT/enable
DIALOG:SEND       **%QStart: VIRT/enable
DIALOG:SEND       ###
DIALOG:SEND       ### Please specify value for 'VIRT/enable':
DIALOG:SEND       ### Response is VALUE VIRT/enable=type:value or
ABORT VIRT/enable
DIALOG:SEND       ***Q:VALUE VIRT/enable
DIALOG:SEND       **%QEnd: VIRT/enable
DIALOG:RECEIVE    VALUE VIRT/enable=bool:true

"SEND" is what the host-deploy sends, "RECEIVE" is what the engine
replies.

So host-deploy sent a prompt asking for a customization command,
the engine sent the command 'env-query -k VIRT/enable', host-deploy
then asked the engine to provide a value for 'VIRT/enable', and the
engine replied 'VIRT/enable=bool:true'.

As I said, you can ignore it for now. But IMO this isn't specific
to Debian - search a bit and you'll find other similar cases.

Last one will indeed be very interesting, but isn't mandatory for you
to continue, if your stated goal is to have a Debian host managed by
an oVirt engine. You can manually install all your stuff on the host,
and use offlinepackager so that host-deploy will not try to install
stuff for you. You'll then have a harder first-time-install, and
will miss checking for updates etc. For these you'll indeed need to
write something like debpackager, and probably minideb as well -
engine-setup uses it directly, as otopi's packager isn't enough for it.

I'd like to mention another point. As explained above, when the engine
adds a host, it copies to it a bundle (tarfile). This bundle is not
rpm/yum/dnf specific - it should work also on Debian. Normally,
ovirt-host-deploy (the rpm package) is installed only on the engine
machine. So if you do not care about the engine side for now, you
should be able to try adding a Debian host to your engine already -
just configure offline packager. This might be easier to debug then
by manually running ovirt-host-deploy.

Best,
