Sorry Shin, I meant to get back to answer this when you asked, but got 
distracted and then forgot about it (which was rude of me - sorry). I also 
needed to "document it for myself" because, over a year later, I've ran into 
the same issue (see 
https://lists.ovirt.org/archives/list/users@ovirt.org/thread/7CXIPLSXOGL3EDWQTPCRCJU3CHWVAN4R/).

In short, (to now answer your Q and to document it for me, plus anyone else who 
runs across this) the solution (for me) was to accept the default names for the 
Data Center and the Cluster and then edit the names to what was 
required/desired once the engine was successfully deployed. This thread 
(https://lists.ovirt.org/archives/list/users@ovirt.org/thread/IDLGSBQFX35EHHGBE2FLPVZANTL7U7BL/#BTOCNIOUUORNI7ESIXNATPLKBMN2VPQ3)
 gave me the clue (the 2nd time around).

Hello Dulux-Oz

Thanks for your rep, good to know working fine.
Then, what was the problem of the "Host is not up..." issue and how did *you* 
solve that..?
Hope my question not bother you.

Regards, 
Shin

Hi Shin,

Yeah, all sorted, all working - even the stuff that I had crop-up since then.

As it stands at the moment we've got a 3-node self-hosted oVirt Cluster using 
Gluster and iSCSI Storage provided by a hyper-converged Gluster Cluster (the 
same physical boxes ad the oVirt Hosts) and a 3-node Ceph Cluster using 3 iSCSI 
Gateways - a total of 6 servers if anyone is counting. There's about 140 TB of 
storage space, about 187 GB of VM-usable RAM, and about 190 VM-usable GFlops.

Cheers

Hi Matthew

Sorry if you already solved the problem.
The default HE admin name looks like changed to "admin@ovirt".

BTW how did you solve the original problem?
I also had same problem like "Host is not up..." and I modified the ansible 
role which calls "ovirt.ovirt.ovirt_host_info" to be skipped.. in the end. Bad 
solution.

Regards,
Shin

Hi Matthew,

It should be as simple as:

Actually, I just thought of another question:

I've got console root access to the Engine VM: How hard is it to change the URL 
GUI "admin@local" password from there - and what is the process?

I ask because this'll mean I won't have to do a re-install to reset the bad 
password I mentioned above.

[ovirt-users] Re: Please, Please Help - New oVirt Install/Deployment Failing - "Host is not up..."

[Matthew J Black]

***WOOHOO***

Finally - *FINALLY* - I've got a clean install!

As I said in my last post, I stripped the three hosts back to bare metal and 
reinstalled *everything* from scratch, as per the oVirt doco - and late this 
afternoon the deployment script finished without any errors and I could pull up 
the Engine Web page.

So all good (except see below)  :-)

Questions:
- When logging in to the Engine URL for the first time, is the username "admin" 
or "admin@internal"?
- Just to make it 100% clear in my own muddled mind: Step 5.4 (of the oVirt CLI 
Install doco) is performed on the Engine VM, isn't it, and *not* on the host, 
right?

I'm having trouble logging in - but that's OK because I'm pretty sure I know 
what the issue is (bad password :-) ) so I'm going to tackle that one tomorrow.

Thanks for the help everyone (include the OOB help) - if someone could please 
confirm these final(?) two questions that'd be great.

Cheers

OK, so as I said I was going to do I've now gone through the logs.

I've place the log files into DropBox 
(https://www.dropbox.com/sh/eymwdy8hzn3sa7z/AACscSP2eaFfoiN-QzyeEVfaa?dl=0)

There was only one significant part of the logs (at least that what it appears 
to me) and I've included that extract below:

Skipped, so this means that host_result_up_check (the check itself) didn't fail.

> > [ INFO  ] ok: [localhost]

This means that we entered the block "Emit error messages about the
failure", which means all of the 3 "and-ed" conditions in its "when:"
were true. Sadly, this (the block) isn't logged in itself - see [1]
(and [2], a simple attempt at a workaround that I eventually gave up
on). This means that we did get a host in the result, and that its
status is "non_operational".

This means that the above tasks did manage to generate an
"error_description", but that for some reason it was not output to
your console. This is quite weird, I have no idea how this happened.

I am confident I tested it back then [3], and also can find examples
(very few) where it worked for others [4]. Incidentally, [4] does not
include the task name "Notify with error description", and neither
google finds it anywhere, but your output above does include it. [4]
does include the actual text, but your output does not. Perhaps this
is a change in ansible since then or something similar. Would you like
to create a github issue in [5] about it? Something like "HE
deployment gets stuck without details" or whatever, and add relevant
parts of the logs. Thanks.

This isn't the case here - it paused due to a problem, but didn't emit details.

Can you please check the logs in /var/log/ovirt-hosted-engine-setup?
You most likely should be able to find the messages there, including
the URL to the web admin if needed.

If you do that, it will shortly thereafter fail in the following task
"Check if the host is up".

No. I guess you did ask for that, maybe by mistake. The default is not to pause.
can you get to webadmin now and confirm th host state?
and/or just remove that file and let it continue...

[ovirt-users] Re: Please, Please Help - New oVirt Install/Deployment Failing - "Host is not up..."

[Matthew J Black]

Hi All,

Long story short, I just tried to do a `hosted-engine --deploy` on a brand, new 
"out-of-the-box box", following the oVirt doco *exactly*, and while I got past 
my "Host is not up" issue, but almost exactly afterwards got this in my console 
(I've included the couple of lines leading up to the "Host is no up" step):

I didn't ask for script to pause, so I need to ask: Is this normal?

I'm about to have a look at the logs, but its late here at the moment so I 
wanted to get this up on the mailing lists so I don't loose too much time while 
I'm asleep and everyone else is awake (& vice-versa).

Good.

It should.

At this point, the operation that is attempted and which is failing
with the error you see in engine.log ("Failed to authenticate
session"), is done using Java code, using the Java library
apache-sshd, not the command line ssh. Some of the relevant code is
here:

https://github.com/oVirt/ovirt-engine/blob/master/backend/manager/modules/bll/src/main/java/org/ovirt/engine/core/bll/hostdeploy/AddVdsCommand.java

I do not know this code well, sorry, nor the specifics of apache-sshd
vs openssh (and there are such "specifics", as can easily be seen by
looking at the engine git log).

I think this should work more or less like this:

After running engine-setup, and when the engine is already up, we
fetch the public key of the engine from it, and store it in your
authorized_keys file. This is done here:

https://github.com/oVirt/ovirt-ansible-collection/blob/master/roles/hosted_engine_setup/tasks/bootstrap_local_vm/05_add_host.yml#L36

  - name: Set Engine public key as authorized key without validating
the TLS/SSL certificates

I do see this in your log in dropbox.

Do you see /root/.ssh/authorized_keys on the host (with a timestamp
similar to the log line)?

If so, you can try this, from the engine VM:

ssh -v -i /etc/pki/ovirt-engine/keys/engine_id_rsa ovirt_node_1.mynet.local

If this does not work, you can continue debugging this until you
manage to understand/fix. Perhaps check sshd config etc.

If it does work, it means the issue might be due to incompatibility
between apache-sshd and openssh and/or the configuration.

At this point, you should be able to log into the admin UI (the pause
message provides a link) and try to manually add the host. It seems
like this didn't work for you. This is because "host_result_up_check"
is "failed", and we pause only if it succeeded and the host is
returned with status "non_operational". Feel free to create an issue
to make the code pause also if "host_result_up_check" is "failed" -
not sure why we do not, perhaps we did have a reason. Anyway, you can
force the code to pause after trying to add the host but before
checking if this worked, by passing
"--ansible-extra-vars=he_pause_host=true".

You can also check/share more of engine.log - there might be more
information prior to the failure (but as I said, I do not know this
code well).

You can try running sshd (the server) with debug info and check its
own log - the issue might be due to incompatible keys on one or both
of the sides, or something like that.

Sorry that I do not remember if you wrote this before - is this your
first attempt to install oVirt? If so, perhaps try first to start with
a clean host, without any custom configuration (e.g. of sshd), and see
if this works for you. If you do have access to a successful setup,
you can more easily compare.

Good luck and best regards,

[Matthew J Black]

OK, so, with all the tooing-and-frowing things stand as follows (@03:15UTC 
25-Oct-2022):

- I managed to solve the "DNF Timeout" issue (see my post "Local (Deployment) 
VM Can't Reach "centos-ceph-pacific" Repo") and so simplified the deployment 
command to `hosted-engine --deploy`. Unfortunately this still results in a 
"Host is not up" error, with the logs as per before.

- As mentioned elsewhere in this thread I uploaded the (previous) logs to 
Dropbox along with a couple of other relevant(?) files:
https://www.dropbox.com/sh/eymwdy8hzn3sa7z/AACscSP2eaFfoiN-QzyeEVfaa?dl=0

- I followed the suggestion of  ajude.pereira (see post in this thread) but 
this did not resolve the issue.

- As per one of my other posts in this thread, digging into the logs further 
revealed this issue: "Failed to authenticate session
with host 'ovirt_node_1.mynet.local': SSH authentication to 
'root(a)ovirt_node_1.mynet.local' failed. Please verify provided credentials. 
Make sure key is authorized at host"

- I also did a `hosted-engine --deploy --ansible-extra-vars=he_pause_host=true` 
(as per the suggestion of Konstantin - see post in this thread) and tried to 
work out why ssh wasn't working. I ssh'd into the deployment VM and then 
attempted to ssh back into the deployment host (ie `ssh 
root@ovirt_node_1.mynet.local`). While I could connect, I was asked for the 
root's password. I was under the impression that this was supposed to be a 
"password-less" operation. As I do not provide the 
root@ovirt_node_1.mynet.local password anywhere in the deployment script, I 
suspect that this is why I'm getting the "Host is not up" error.

- To reiterate: the host'd sshd_config file is configured as per the oVirt 
documentation.

So am I wrong in my understanding of the password-less ssh-nature of the 
situation and how the deployment script is supposed to work?

Also, does *anyone* have any pointers, suggestions, or can otherwise help me 
out - thanks.

Cheers

[ajude . pereira]

Ran into the same issue. 
This is causes by ansible using some combination of python 3.6 and 3.9 which 
have separate package stores. 
Fix was to install pip 3.9 and then using pip3.9 install netaddr and jmespath. 
> python3.9 -m ensurepip --upgrade
> pip3.9 install netaddr jmespath

[ovirt-users] Re: Please, Please Help - New oVirt Install/Deployment Failing - "Host is not up..."

[Matthew J Black]

Question: Are the hosted-engine flags 
"--ansible-extra-vars=he_offline_deployment" & 
"--ansible-extra-vars=he_pause_host" mutually exclusive?

The reason I ask is that when I run "hosted-engine --deploy --4 
--ansible-extra-vars=he_offline_deployment=true 
--ansible-extra-vars=he_pause_host=true" the script runs into the "DNF Timeout" 
issue I mentioned in the `Local (Deployment) VM Can't Reach 
"centos-ceph-pacific" Repo`, and running "hosted-engine --deploy --4 
--ansible-extra-vars=he_offline_deployment=true" doesn't encounter that issue.

In other words, I can't do what you suggest (thank you for the suggestion, btw) 
because I either run into the "DNF Timeout" issue (and thus don't get anywhere 
near being able to log into the the engine), or I can't set 
"--ansible-extra-vars=he_pause_host" to true.

Any ideas?

Cheers

[Volenbovskyi, Konstantin]

Hi,
It seems that you are here: 
https://github.com/oVirt/ovirt-ansible-collection/blob/33d273e2e823bf0c2440a9009a0d38d1b383c27c/roles/hosted_engine_setup/tasks/bootstrap_local_vm/05_add_host.yml

I would say that in this case following is likely:
1) virsh list (with authentication) shows that hostedEnginelocal is running
2) SSH is successful from ovirt host due to temporary entry in /etc/hosts
3) You might see that ovirt-engine service is running on port 443 and then it 
is exposed
as port 6900 on your ovirt host.

Check out 
https://github.com/oVirt/ovirt-ansible-collection/blob/33d273e2e823bf0c2440a9009a0d38d1b383c27c/roles/hosted_engine_setup/tasks/bootstrap_local_vm/05_add_host.yml#L132
That means you can provide he_pause_host Ansible variable with value 'true' and 
take a pause for troubleshooting here.

So in case above is correct for your situation - then you should do port 
forwarding from port 6900
to port 443 on your local workstation/somewhere where you have browser and 
connect to ovengine GUI
Then you go to 'Hosts' and see if the host is 'up'. It is unlikely that it will 
be up.
Alternatively, there is REST API on this I think (=the one used by Ansible 
module in 'wait for host is up' task), but I don't know specifics.

In GUI go to 'Setup host network' and make sure that network bridge/network 
interfaces and maybe try to assign this network
(be careful: you might also connectivity to your ovirt host). Check those 
DHCP/Static IP assignment aspect.

There could be too many assumptions above, but hopefully it gives you something 
to use within troubleshooting.

BR,
Konstantin

Hi Everyone,

Could someone please help me - I've been trying to do an install of oVirt 
for *weeks* (including false starts and self-inflicted wounds/errors) and it is 
still not working.

My setup:

- oVirt v4.5.3
- A brand new fresh vanilla install of RockyLinux 8.6 - all working AOK
- 2*NICs in a bond (802.3ad) with a couple of sub-Interfaces/VLANs - all 
working AOK
- All relevant IPv4 Address in DNS with Reverse Lookups - all working AOK
- All relevant IPv4 Address in "/etc/hosts" file - all working AOK
- IPv6 (using "method=auto" in the interface config file) enabled on the 
relevant sub-Interface/VLAN - I'm not using IPv6 on the network, only IPv4, but 
I'm trying to cover all the bases.
- All relevant Ports (as per the oVirt documentation) set up on the firewall
- ie firewall-cmd --add-service={{ libvirt-tls | ovirt-imageio | 
ovirt-vmconsole | vdsm }}
- All the relevant Repositories installed (ie RockyLinux BaseOS, AppStream, 
& PowerTools, and the EPEL, plus the ones from the oVirt documentation)

I have followed the oVirt documentation (including the special 
RHEL-instructions and RockyLinux-instructions) to the letter - no deviations, 
no special settings, exactly as they are written.

All the dnf installs, etc, went off without a hitch, including the "dnf 
install centos-release-ovirt45", "dnf install ovirt-engine-appliance", and "dnf 
install ovirt-hosted-engine-setup" - no errors anywhere.

Here is the results of a "dnf repolist":

- appstreamRocky Linux 8 - 
AppStream
- baseos Rocky Linux 8 
- BaseOS

- powertools Rocky Linux 8

So I kicked-off the oVirt deployment with: "hosted-engine --deploy --4 
--ansible-extra-vars=he_offline_deployment=true".

I used "--ansible-extra-vars=he_offline_deployment=true" because without

OK, so I think I've identified the issue. I found these lines in the engine.log 
file:

2022-10-20 17:27:36,785+11 ERROR 
[org.ovirt.engine.core.bll.hostdeploy.AddVdsCommand] (default task-1)

2022-10-20 17:27:36,822+11 ERROR 
[org.ovirt.engine.api.restapi.resource.AbstractBackendResource] (default 
task-1) [] Operation Failed: [Cannot add Host. SSH authentication failed, 
verify authentication parameters are correct (Username/Password, public-key 
etc.) You may refer to the engine.log file for further details.]

So my next set of questions:

- I don't recall anywhere in the deployment script being asked to supply the 
root login credentials for ovirt_node_1.mynet.local (the host), so what have I 
missed?
- I don't recall being asked to supply a ssh cert for logging into 
ovirt_node_1.mynet.local. The only ssh cert being asked about (and its marked 
as "Optional") is one to log into the deployed engine *after* it is deployed 
(Step 16 of "5.3. Deploying the self-hosted engine using the command line"). Am 
I missing something here?
- In the Prerequisites section of 5.3 the doco mentions "The self-hosted engine 
setup script requires ssh public key access using 2048-bit RSA keys from the 
engine virtual machine to the root account of its bare metal host." and then 
talks about having various settings set in the host's sshd_config file. In the 
host's authoized_keys file there is an RSA key (not placed by me) which I 
assume the deployment script placed there. Again, what am I not understanding 
about this?

I've checked the host's sshd_config file and all of the requirements listed in 
section 5.3 of the doco are there (the PubkeyAcceptedKeyTypes is being picked 
up from the system-wide crypto policy, which are set to DEFAULT, which meets 
the specified 2048-bit RSA keys).

I've included all the logs with the string "ERROR" in this DropBox folder, 
along with a couple of other relevant(?) files: 
https://www.dropbox.com/sh/eymwdy8hzn3sa7z/AACscSP2eaFfoiN-QzyeEVfaa?dl=0

Could someone please be kind enough to point out where things are going wrong?

Cheers

You can upload to some file sharing service (dropbox, google drive,
etc.) and share a link. If it's just not-too-long text you can use
some pastebin (might be more or less convenient for some readers, I
didn't do a poll).
