Description of problem:

Sandy Berger reported on the users list that:

> since the 4.1 upgrade the console button in the toolbar for the hosted engine is dimmed in the 
> GUI. That is still the case. Is that expected behavior with 4.1 or is there some other issue
> going on?

> Also, when I use the command "ssh -t -p 2222 ovirt-vmconsole@engine," I get a menu of VMs that
> I can choose from and get a serial console to them. That option has never worked for the hosted 
> engine. The engine shows up as a menu item but selecting it yields a socket error. This works 
> successfully on the other VMs.

Version-Release number of selected component (if applicable):

oVirt 4.1

It is strongly recommended to use ttyS0 (legacy serial driver emulation) and not hvc0 (newer virtio serial driver) because we had reports
of kernel panics (!!!!) using the new driver.
We are going to re-evaluate this setting for 4.2.0, and, perhaps, later 4.1.z, but for 4.1.0 this is still valid.

In terms of Vm configuration, the console device should have the "consoleType" = "serial" setting.

This is the default Engine sends.

Not sure what HE is doing, but this explains why it works with not-HE VMs.

Nikolai, can you check if this is working or not?

Comment 4 Nikolai Sednev 2017-02-15 12:08:57 UTC 
In Red Hat Virtualization Manager Version: 4.1.1-0.1.el7 serial console button is not greyed out as appears within the attachment, it is disabled by default, but then it is possible to select it and enable, but selection not being saved and after looking again on that option it is shown as not selected, although I've marked it as selected and committed with "OK".

You could probably hit the https://bugzilla.redhat.com/show_bug.cgi?id=1364132.

I've tested serial console on HE for 4.1.1-0.1 and results are as follows:
"ERROR: Console '8dc1d363-1127-44c5-881a-c0e3a55c69f1.sock' is not available"

Comment 5 Martin Sivák 2017-02-15 12:16:56 UTC 
Nikolai, can you check whether the console device is present? You can attach the virsh -r dumpxml output and the local vm.conf hosted engine is using (it is in /var/lib I think).

Comment 7 Simone Tiraboschi 2017-02-15 13:28:50 UTC 
We have two VMs in the engine DB, the hosted engine one and one where the virtio serial console is working.

engine=# select vm_name, vm_guid, console_cur_user_name, console_user_id, allow_console_reconnect, emulated_machine from vms;
   vm_name    |               vm_guid                | console_cur_user_name | console_user_id | allow_console_reconnect |  emulated_machine

(2 rows)

Note that on the hosted-engine-vm we are also missing emulated_machine value.

On the VM where the serial console it's working we have two devices:

engine=# select device_id, vm_id, type, device, address, spec_params from vm_device where vm_id='3bbe962a-a5af-439a-ac39-b8f641691c54' and (device = 'virtio-serial' or device = 'console');

Try editing the hosted-engine VM to add the virtio serial console gives no error at all in engine.log and server.log
Comment 8 Francesco Romani 2017-02-16 11:33:23 UTC 
Here's a good example of how the console device should be sent to Vdsm

{u'device': u'console', u'specParams': {u'consoleType': u'serial', u'enableSocket': u'true'}, u'type': u'console', u'deviceId': u'a9789005-0c76-4e3d-b723-cf15f3508b00'}

This matches the engine side shown by Simone in https://bugzilla.redhat.com/show_bug.cgi?id=1420115#c7

Comment 9 Martin Sivák 2017-02-16 12:27:32 UTC 
Graphical spice console according to fromani:

{u'device': u'spice', u'specParams': {u'fileTransferEnable': u'true', u'spiceSslCipherSuite': u'DEFAULT', u'spiceSecureChannels': u'smain,sinputs,scursor,splayback,srecord,sdisplay,ssmartcard,susbredir', u'copyPasteEnable': u'true'}, u'type': u'graphics', u'deviceId': u'a2a13c5d-cc2c-4556-abd0-605b3bbf83fb'}
Comment 10 Martin Sivák 2017-11-24 10:35:18 UTC 
This is likely going to be resolved on Node 0 based hosted engine deployment. It will be even better once libvirt xml is somehow passed to hosted engine.
Comment 11 Martin Sivák 2018-01-17 11:58:14 UTC 
Will be probably fixed by https://gerrit.ovirt.org/#/c/86435/
Comment 12 Nikolai Sednev 2018-02-15 15:11:52 UTC 
Deployed with node 0 on NFS and still being reproduced on these components on engine:

Comment 16 Martin Sivák 2018-02-28 12:22:00 UTC 
Nikolai, can you check if the serial console is actually enabled in the Edit VM dialog inside the webadmin?
Comment 17 Nikolai Sednev 2018-02-28 14:10:37 UTC 
(In reply to Martin Sivák from comment #16)

It was not enabled in UI when I tested it last time and changing it was not taking any effect.
Comment 18 Nikolai Sednev 2018-02-28 14:11:58 UTC 
See https://bugzilla.redhat.com/show_bug.cgi?id=1420115#c12.
Comment 19 Martin Sivák 2018-02-28 15:22:53 UTC 
Simone, we should probably enable the console device when creating the VM using Ansible.
Comment 20 Simone Tiraboschi 2018-02-28 18:15:27 UTC 
Nothing console related in 
http://docs.ansible.com/ansible/latest/ovirt_vms_module.html

Ondra, any hint?
Comment 21 Ondra Machacek 2018-03-01 10:20:21 UTC 
It will be available in Ansible 2.5.

Not working or worked? Can you attach # virsh -r dumpxml HostedEngine ?

The deployment is working, but the button is not working.
Just as it was described previously in https://bugzilla.redhat.com/show_bug.cgi?id=1420115#c17.

Comment 25 Simone Tiraboschi 2018-03-19 17:08:58 UTC 
Is the serial console enabled on engine side if you try to edit the engine VM configuration?

The console checkbox is not marked by default after clean deployment, if trying to enable the checkbox and then clicking OK, then entering again in to edit to see if change was taken in effect, then clearly see unmarked checkbox.

It will definitively need further investigation, postponing to 4.2.3 for now
Comment 28 Simone Tiraboschi 2018-04-16 13:56:39 UTC 
I think it could be due to https://gerrit.ovirt.org/#/c/90288/
Comment 29 Simone Tiraboschi 2018-04-17 16:01:22 UTC 
1528868 is now on MODIFIED, setting this to ON_QA since nothing else seams required here.
Comment 30 Nikolai Sednev 2018-04-22 14:45:29 UTC 
Again, checkbox is not marked after clean deployment of Node 0, please see the screenshot within the attachment.
If marked, then after checking it, it appears unmarked, like nothing was ever done, please see screencast.

Looks like the <console> device is missing here, and this explains why virtual serial console doens't work.
Worth mentioning that the serial device is instead present.
Comment 35 Martin Sivák 2018-04-24 10:28:23 UTC 
SSH proxy will not work anyway in 4.2 as there is a libvirt bug that limits the length of the UUID - see https://bugzilla.redhat.com/show_bug.cgi?id=1560666 and https://bugzilla.redhat.com/show_bug.cgi?id=1560976

hosted-engine --console tool should work as expected.
Comment 36 Michal Skrivanek 2018-04-26 12:25:15 UTC 
I believe you guys are talking about completely unrelated hings. The original bug report is about "console button" which is indeed likely related to graphics devices being unplugged as Simone noted in comment #28. The button should work now

The other comments are talking about serial console and hosted-engine --console which is not relevant to this bug

Nikolai, please verify that after the upgrade you can open a *graphical* console using the "Console" button in webadmin.

I agree, we should probably split this into two distinct bugs.
Let's focus the verification of this just on the graphical console and use https://bugzilla.redhat.com/show_bug.cgi?id=1561964 for the serial console (either from hosted-engine --console and vmconsole proxy).
Comment 38 Nikolai Sednev 2018-04-26 15:29:24 UTC 
If this bug is about GUI, then moving to verified as its working fine in WEBUI.
I was able to connect to the engine's VM using VNC/Spice.
