As long as the storage domain is in tact you should be able to recover 
everything. And it does sound like this is the case as the VMs are still 
running. Basically you just install a new engine somewhere and then do the 
following:

- Create new Data Center
- Create new Cluster
- You will need a host to add to your cluster. Add this host.
- Create a small temporary storage domain, this will allow you to bring up the 
data center which in turn will allow you to IMPORT the existing storage 
domain.
- Once the DC is up, you can 'import' the existing storage domain, it will 
warn you that the storage domain is still attached to another DC, but since 
that engine is gone, you can ignore that.
- Once the new DC is imported you can stop/detach/remove the small temporary 
storage domain, which will make the imported storage domain, the master 
domain.

Once all that is done, you can simply go to the storage domain, and 'import' 
whatever VM/template you have stored on the storage domain, and it will show 
up in the VM/template list. Then you add all your hosts and you should have a 
running environment again.

postgresql configuration, its a 100 by default. You can either increase that 
number to something higher, or see if you can understand what is using up the

According to that exception there was an issue connecting to the engine 
database to retrieve some network related information, which in turn resulted 
in the host going non operational. I would check the engine.log in /var/log/
ovirt-engine on the engine machine to see if there is more information on why 
the connection failed. Depending on how many concurrent connections are being 
used it is possible none were available when you tried. Now whatever was using 
the connections has stopped using them, and they were available again.

Try increasing the number of connections available in the postgres 
configuration to solve the problem.

James,

Yes its possible, when you install (or re-install) a PHYSICAL host, in the 
host popup dialog there is a kernel tab. Enable 'Nested Virtualization' kernel 
parameter. Once that is enabled and the host is rebooted then you can use VMs 
as VDSM hosts for your setup.

Some gotchas:
- Make sure your cluster cpu type actually matches your physical hosts, if you 
select a wrong one then the exposed CPU options will be wrong and the nested 
virtualization will not work properly.
- You will need to enable mac spoofing for the networking to work correctly.
- VMs running inside a host that is a VM itself will likely have a fairly 
significant performance hit due to the nested virtualization.

You need postgresql 9.5, following the information here should give you 
everything you need:

https://www.ovirt.org/release/4.2.1/

Also look at the information below 'What's New in 4.2.1' it has some 
information on upgrading the uuid generation which requires some manual steps.

I believe you can turn of this check by setting:

SSO_CALLBACK_PREFIX_CHECK=false
/etc/ovirt-engine/engine.conf.d/11-setup-sso.conf

but you should check if your ENGINE_FQDN matches what you are using in /etc/

Don't know too much about the VDSM side of things. But obviously its looking 
for a storage domain it can't find anymore. You can try restarting VDSM (won't 
affect running VMs) and see if rescans the available storage domains and won't 
try to access it during the migration of the VMs. Other than that I don't 
know.

As long as you don't destroy the data on your data domain you can rebuild the 
engine and hosts and then import the existing data domain without too many 
issues. I have destroyed my engine database many times, and I am still using 
the same VMs from the same data domain.

Here is what I do when I mess up my database to the point I have to make a new 
one:

1. Recreate the engine and database, so that I have basically have an empty 
engine with no hosts and VMs.
1.1 (Optional) make a new DC that is not default. and add a cluster.
2. Add my hosts (I only have 2 so that is quick and easy).
3. Add a throw away data domain (This is needed to get the DC up so I can 
import the existing data domain).
4. Import (NOT new, import) the existing data domain.
5. Do to Storage->Storage Domains->VM import and import the VMs I want.
6. Same for templates and disks if needed.
7. After you have imported the VMs/Templates/Disks you can detach and remove 
the throw away data domain and the one you imported becomes the master domain.

Note if you want to move VMs between your play ground and more serious system 
you can simply detach your data domain from the play ground, then attach it to 
the serious engine (so you have 2 engines, one play ground and one serious) 
and import which VMs you want. That way you won't run into issues with 
configuring networks and stuff like you experienced.

This is highly likely a DNS issue, the engine tries to resolve itself and if 
it can't, it takes a long time to load the webadmin (Not sure why it does 
this, but fixing the DNS will fix the slow loading).

Have you looked at ansible? You can make some playbooks that call the REST api 
and have it deploy the VMs for you. Or if you feel like writing your own

You can also 'and' and 'or' different parameters, for instance

api/vms?search=name%3DVM1+or+name%3DVM2

which will return VM1 and VM2 if they exist. Note that you will need to URL 
encode your search string to replace all the '=' with %3D and space with +, 
etc. The only = that shouldn't be encoded is the = after search.

For an easy way to find what is available to search on for a particular 
entity, if you go into the webadmin in the search bar you can start typing and 
it will auto complete the different available options. AFAIC those match 
exactly to the search in the REST api.

You probably need to refresh the ISO list, assuming 4.2 go to Storage -> 
Storage Domains -> , click on the name, and go to the images 
detail tab. This should refresh the list of ISOs in the list and the ISO 
should be listed, once that is done, it should show up in the drop down when 
you change the CD.

Interesting, as that name is not long enough to trigger the name length 
validation. You have 64 characters total for the name. I just tried your 
scenario on the latest master branch, and it worked as expected, it created 
the template from the snapshot without issues with that exact same name.

I don't see any recent changes to the frontend code for that dialog either. If 
you look in the engine.log does it say anything? I can only assume some 
validation is failing, and that validation message is not properly propagated 
to the frontend, but it should show something in the backend log regardless.

So api.addSubTab works on adding a 'detail' tab, aka when you click on lets 
say the VMs name, and go to the detail view, addSubTab will add another tab in 
there.

What you want to do, is currently NOT possible. I have a TODO in my long list 
of items to add that capability to the UI plugin API. When the API was 
designed the secondary menus like Networks didn't exist, it was all main tabs 
or sub tabs. The primary and secondary menus are just a way to organize the 
main views instead of having a giant list of menu items. For now I would just 
put it in a primary menu until I get a chance to update the api to allow for 
you to add it to a secondary menu.

Well you found a bug, I will be posting a patch soon. To bypass the problem 
add the following:

api.addMainTab('FooTab','xtab123','http://foo.com/, {priority: N});

Where N is a number between 0 and 5

This will determine where the new menu item will show up in the menu, 0 being 
at the top below the dashboard, and 5 being right above Events. Normally it is 
supposed to simply add to the end, however due to the bug it won't.

Re: [ovirt-users] oVirt 4.2 WebUI Plugin API Docs?

Unfortunately no, I haven't had a chance to create updated documentation. 
However the first two links are mostly still accurate as we haven't done any 
major changes to the API.

Some things to note that are different from the API documentation in https://
www.ovirt.org/develop/release-management/features/ux/uiplugins/ for 4.2:

- alignRight no longer has any effect, as the UI in 4.2 no longer respects it.
- none of the systemTreeNode selection code does anything (since there is no 
more system tree)
- As noted in the documentation itself the RestApiSessionAcquired is no longer 
available as we have a proper SSO mechanism that you can utilize at this 
point.
- Main Tabs are now called Main Views (but the api still calls them main tabs, 
so use the apis described). And sub tabs are now called detail tabs, but the 
same thing the API hasn't changed the naming convention so use subTabs.
- mainTabActionButton location property no longer has any meaning and is 
ignored.

That is it I think, we tried to make it so existing plugins would remain 
working even if some options no longer mean anything.

Have you tried right clicking on the host, and select 'Confirm Host has been 
rebooted' that is basically telling the engine that the host is fenced, and 
you should be able to put it into maintenance mode. It will ask confirmation 
but we know the host has been rebooted and nothing is running.

Looked into it, have a patch pending. The good news is, its easy to work 
around by simply making your browser wider until it decides to change the 
layout. For some reason it decided the height of the container of the field 
was double what it was supposed to be and thus the field (in this case a drop 
down) was on top of the check box and eating the click.

The layout is adaptive, It has a large/medium/small/xs layout. Depending on 
the size of the screen it will it will take one of those layouts. I am 
guessing that is a medium layout. And looking at the bug it appears to have 
decided that the labels should be above the fields.

I am fairly certain there is no logic to disable some based on the layout. 
What highly likely is happening is that part of another widget that is 
transparent is on top of the checkbox and eating the clicks and thus nothing 
happens.

With the whole UI rework haven't had the chance to look at this dialog in a 
while. It appeared to be working fine and I had bigger fish to fry. I will 
take a look at the bug and see if I can fix it the issue for you.

AFAIC engine-setup will create the files needed. Try running engine-cleanup 
and maybe it will remove everything needed and then running engine-setup 
again?

But if all else fails you should be able to create a fresh engine, and after 
you have added a host, you should be able to import the existing storage 
domain (like you noted the VMs are still there).

Running engine-setup on the engine machine should re-generate the keys.

Short answer: No, we removed it on purpose.

Long answer: No, here are the reasons why:
- We are attempting to get the UI more mobile friendly, and while its not 100% 
there yet, it is actually quite useable on a mobile device now. Mobile devices 
don't have a right click, so hiding functionality in there would make no 
sense.
- You can now right click and get the browsers menu instead of ours and you 
can do things like copy from the menu.
- We replicated all the functionality from the menu in the buttons/kebab menu 
available on the right. Our goal was to have all the commonly used actions as 
a button, and less often used actions in the kebab to declutter the interface. 
We traded an extra click for some mouse travel
- Lots of people didn't realize there even was a right click menu because its 
a web interface, and they couldn't find some functionality that was only 
available in the right click menu.

Now that being said, we are still debating if it was a good move or not. For 
now we want to see how it plays out, if a lot of people want it back, it is 
certainly possible we will put it back.

We are always working on improvements. Also check out the new user portal if 
that is something you are interested in. Its also much faster and better than

So you successfully (well at least the UI told you it was successful) imported 
the ISO domain. And now the grid is empty? Is it empty in that you see nothing 
but the header, or is it empty with a note saying no items found?

Unfortunately no, which is a bug, it should also store any column size changes 
but for some reason it doesn't remember those either. I think there is a bug 
open on those but not sure.

Default logout timeout is 30 minutes. You can configure this using engine-
config

For instance:

engine-config -g UserSessionTimeoutInterval will return 30

you can change it using engine-config as well for instance

engine-config -s UserSessionTimeoutInterval=60 will set it to 1 hour.

If logging is taking a long time and the UI is not very responsive you 
probably have one or more of the following:

The engine is running in a VM and there is not enough entropy (logging in 
takes a long time).
The DNS/rDNS is not configured properly and the engine cannot resolve itself 
(Sluggish UI, things take 30-60 seconds to happen in UI)

If the engine VM is up, but the GUI is down, I think that either Apache or 
Jboss is down. Apache is unlikely, so I would guess Jboss. To figure out why 
Jboss is down look in /var/log/ovirt-engine/ at boot.log, and server.log, also 
check out engine.log but the first two should tell you why Jboss is down.

I think you are misunderstanding the architecture of oVirt a little bit so I 
will try to explain, and then I will address your particular issue. Basically 
the following happens:

1. The engine talks to the hosts (which are running VDSM). The engine itself 
doesn't actually know about or care about the storage at all, it just talks to 
the hosts. If storage operations need to happen it tells a special host, the 
SPM to do them. Only one host at a time is SPM.
2. The hosts talk to the storage through whatever mechanism is provided by the 
storage (FC, iSCSI, NFS, Gluster, etc). Management of the storage happens 
through the SPM host (this is to prevent simultanious operations that could 
corrupt the storage). This also means that under normal circumstances the 
available disk space on the hosts is not used (unless you are running some 
kind of hyper converged setup, which is a whole other story). Of course a lot 
of this is a little more nuanced than what I am saying, but in general the 
storage is considered separate from the hosts.

When you add a host to the engine you are simply saying this machine is 
available to RUN VMs and it should be able to communicate with the storage 
domains. Which leads to your question about why are you not seeing the storage 
available on the engine machine. In the NFS dialog you have to specify a HOST 
to use to connect to your storage (Not sure why, since I figured the SPM would 
be a good default, but you should ask the storage guys). Anyway I guess the 
host you pick will be the one that does the checks and mounts the NFS share 
and creates the storage domain on the NFS.

Now in your case you should create the NFS share on the engine machine, make 
sure it is visible to all your hosts, and pick one host from the list to 
connect to that share and configure the domain on it (You will have to specify 
the mount/etc). So at that point the machine with the engine, will be the 
engine machine AND the storage.

Now this is not a really good idea for production as when that machine goes 
down, you will have lost both your engine and your storage at the same time. 
Causing your VMs to pause, and you lost your ability to manage the environment 
because the engine is down.

If it was a minimal centos then he has to turn on the ovirt repo for whatever 
version of ovirt he 
is running by calling

yum localinstall http://resources.ovirt.org/pub/yum-repo/ovirt-releaseXX.rpm[1]

Where XX is the version of his ovirt, for instance 41

Why not go with hosted engine at that point. hosted engine is basically a VM 
running the engine in the system. There should be lots of guides available on 
how to get it up and running.

If you are trying windows, you will need to install the appropriate drivers to 
make it work. Any linux (well except ubuntu) works out of the box, at least

Yeah when I setup a host for testing I always do:

1. Get minimal install of centos 7.
2. yum install http://resources.ovirt.org/pub/yum-repo/ovirt-releaseXX.rpm 
where XX is the version I am working with.
3. Make sure sshd is up and running and my engine can connect.
4. Install the host through the UI.

Haven't had that sequence fail in years.

If there is a task still running (well the database thinks a task is running 
as obviously the host is gone), you maybe be able to use the taskcleaner.sh 
utility to clear out the running task.

taskcleaner.sh -h will give you all the options.

it should be in /share/ovirt-engine/setup/dbutils/taskcleaner.sh

That should have worked, but if all else fails you can always set the host in 
maintaince in the database doing this in the engine database:

update vds_dynamic set status=2 where vds_id = 

you can figure out the id of the host by doing this

select vds_id from vds_static where vds_name=''

If you are feeling brave you can combine the two into a single statement, but 
I would be sure you have the right host before you do that.

Then once you have updated the status, you can refresh the webadmin and the 
host should be in maintenaince mode and you should be able to remove it 
normally. I would not attempt more manual manipulation of the database than 
setting the status to 2 (which is maintenaince).

IIRC when I had that issue (I removed the host physically before removing it 
from oVirt) I had to do the following:

- Right click in the grid on the host, and select confirm host has been 
rebooted (this is basically you telling oVirt the host has been fenced).
- After a while the host should end up as down (or unknown state).
- You should be able to select maintaince at that point, this might take a 
while (timeouts etc).
- This should put the host in maintaince and you should be able to remove it 
then.

He was not making a joke, there should be a 'power off' button between the 
shutdown and reboot button. If it is not there, that is a problem. Is it also 
not there when you right click on the grid in the menu that pops up?

Yes,

Its available at https:///ovirt-engine/api

In fact the python/java/ruby sdk are just wrappers to calling this api.

That exception is telling you it can't run the queries needed to populate the

That still shouldn't give you just a blank page, the code is written to 
display an error stating unable to display dashboard or something of that

Do you have the ovirt-guest-agent installed and running on that windows VM? If 
not that is highly likely the cause for the warning.

I looked a little closer in the server.log. This in particular stood out:

Grepping the code looks like NMEngineDS has something to do with the 
scheduler. Which is completely out of my realm of knowledge, so I can't help 
there.

Looking at our logs, it appears that on Friday one of your hosts ran out of 
disk space in its logs or temp directory. At which point connectivity started 
to be spotty. I see a bunch of attempts to migrate VMs away from that host 
(ovirttest1). All of them fail. That repeats a ton of times, I forwarded to 
Saturday where it appears you had a bunch of stale locks which also repeates a 
bunch of time until the engine VM gets restarted.

Then I see nothing but restarts of the engine and no apparent errors in the 
engine log.

The server log does however reveal this:

Is your postgresql service running? That is the most likely source of the

Yes you should use the remote viewer. The manager itself is not running the 
VMs, the hosts are running the VMs. So what happens when you click on the 
console button is that it generates a .vv file which your browser then 
downloads. If you associate remote-viewer with the .vv files it will attempt 
to connect to the *HOST* running the VM. Now its entirely possible your 
network topology doesn't allow you to connect to the host, while the manager 
(engine) is allowed to connect to the host.

If this is the case you need to configure a proxy on the engine that forwards 
to the host. Since we don't know your topology we can't say much more. But in 
general your browser connects to the engine which shows you the admin UI. Then 
when you want to connect with a console to a VM, your computer (remote-viewer) 
tries to connect to the host.

The message you are seeing is telling me you can't connect to the host.

Is this a new installation? The odds are highly likely that for whatever 
reason (being a new installation would mean the data is not there) the DWH 
database does not have the completely 24 hours worth of data, if you wait it 
will rotate the missing data out and eventually the 24 hours worth of data 
will appear.

IIRC this capability was added in 3.6, so if you are running 3.5, I do not

Yes, if you right click the header, you will get a popup with all the names of 
the columns and a checkbox, you can enable/disable columns, as well as drag 
and drop column names to re-arrange the order. This should persist on a per 
BROWSER basis (its stored in local storage of the browser).

Download the virt VIEWER from 
https://virt-manager.org/download/sources/virt-viewer/virt-viewer-x64-5.0.msi 
assuming you have a 64 bit windows. If you 
don't there are links to 32 bit on https://virt-manager.org/download/ again 
make sure to download the VIEWER not the manager.

Then in your browser associate .vv files with the virt viewer and clicking the 
console button should be all you need to make it work.

The portal has worked in Chrome since at least oVirt 3.1 maybe even earlier. 
Anything in particular that doesn't work for you?

If you specify a disk FIRST and then try to to change the virtual CPU 
configuration it will no longer work. Basically if you edit/change/add a disk 
and a new window pops up, some stuff that shouldn't have been cleaned up, is 
cleaned up and breaks anything that relies on that, like the check to see if 
the virtual CPU configuration is valid. A bunch of other stuff as well like 
the exception mentioned below.

The DWH reports are no longer available in oVirt since 4.0. The process is 
running because the dashboard uses the data to generate its data. But the

Just to be clear on the flow when this occurs, you do the following on a VM 
that is shut down:

1. Select the VM in the VM grid.
2. Click edit and the edit VM dialog pops up.
3. In the General tab you scroll down a little until you see the instance 
Images widget that has the disk listed. You have 3 options:
  - Edit (edit disk)
  - + (add new row, that will give you the option to attach/create a disk)
  - - (remove disk)
You click - (remove disk)?
4. You get the exception?

All it does is disable the main tab that is added for showing the dashboard. 
If there is something in the dashboard that is messing up your browser, then 
the rename will make that go away (together with the dashboard obviously).

Define insanely slow, is it putting up the spinner for loading? If so you can 
switch tabs while its doing its thing.

Its not a known issue, but if you need to get at the VMs right now and the 
dashboard is in your way, you can always disable the UI plugin that adds it. 
But I suspect there is some other issue that is causing the problem.

In /share/ovirt-engine/ui-plugins there should be a file called 
dashboard.json, rename it to something that doesn't end in json and reload the 
webadmin, that should disable the dashboard.

Yes you can make 01-mystuff.brand and in there put a specific template and 
properties file. In the properties file you can specify if you want to append 
or completely overwrite the welcome page. If you just want to add a link, I 
would suggest appending instead of overwriting.

If you need more detailed instructions let me know. I am very familiar with 
that piece of code (since I wrote it).

Can you provide us with the engine logs. The engine is giving an internal 
server error which is bad and shouldn't happen, but obviously it did and its 
highly likely there is a stack trace in the logs that will give us some idea 
what is going on.

Nicolas,

IIRC this is what the custom serial number setting is for. As far as I know 
what happens when you migrate is that some id that windows looks for is 
changed (because it is generate based on an id at the host level). You can set 
a custom single value regardless of which host the VM is running on by opening 
up the edit virtual machine in the UI, then clicking system, at the bottom 
there is a check box called 'Provide custom serial number policy'. Then you 
can select VM ID.

Once you have done that, if I understand the feature correctly, the ID won't 
change and windows will not think you have new hardware each time the VM 
migrates.

I could be wrong, but I believe this is what you are looking for.

I improved that, I just haven't updated the wiki, as soon as you install the 
symbol maps, and you can recreate the issue, then the UI.log should have the 
unobfuscated stack trace, so you don't have to do all that stuff manually 
anymore.

Hi Brett,

Some my wonderful team mates worked out the problem [1], apparently it is a 
bug in 4.0.6-3 that should be fixed in the next release.

Interesting, those aren't actually UI failures, those appear to be failures 
from backend requests. As in, get me some data, and the query fails for some 
reason, there should be something in the engine log. Let me dig up the ones 
you posted again and take a closer look.

Can you send me a screenshot of what you are seeing? As it makes no sense that 
the UI.log is empty, since the exception handler tries to write to the backend 
UI log.

Are you sure those are the correct logs? The UI.log is empty and the other 
logs don't have much of anything in them.

I can't help you with the OVN stuff, but the error at the top indicates some 
kind of bug in the UI code. If you haven't done so already can you install the 
web admin symbol maps and restart your engine

yum install ovirt-engine-webadmin-portal-debuginfo

Then recreate the issues. Then the UI.log on the engine machine will contain a 
deobfuscated stack trace that can help us in determining the cause of the UI 
issue.

Could you install the symbol maps assocaited with the obfuscated code so we 
can get a readable stack trace. To install the symbol maps please run the 
following command on the machine running the engine (or VM if it is HE).

yum install ovirt-engine-webadmin-portal-debuginfo

Please restart the ovirt-engine process with

systemctl restart ovirt-engine

after you have installed the symbol maps. Then next time you see the message 
in the UI, the stack trace in the log should be readable and we can help you 
better determine what is causing the problem.

Yes currently FF below 47 won't load the dashboard due to FF below that 
version not implementing a particular i18n standard. I believe we implemented 
a polyfill to fix that issue recently, I am just not sure which version of the 
dashboard that was fixed. So if you can't upgrade your browser to a newer 
version, you will have to wait until the polyfill version of the dashboard is 
released.

If you select a VM, it will open up the sub tabs at the bottom of the web 
admin. On the general tab in the second column it will list defined memory, 
guaranteed memory as well as cpu information.

Because clusters don't have a 'status' to display. We wanted to display the 
count but the widgets also want to display a status. Since there is no status 
the widget says N/A

Since 3.6.5 or 6, the deobfuscation happens automatically if you installed the 
mapping files described in the wiki page. You can look at UI.log and it should 
be deobfuscated. It is important that the rpm version of your engine match the 
rpm version of the mapping files.

When you say its still visible, you mean you can still see it in the heat map 
at the bottom right? Does it still show in the donut chart (right one) and 
does it also still show in the top inventory count?

In the edit VM dialog, if you show advanced options, there is a 'host' sub tab 
on the left. If you select that, there is a 'start running on' option. You can 
select the specific hosts(s) radio button. That will enable the multi select 
box that allows you to select a list of hosts this VM can run on. I think that 
will do what you are trying to do?

Okay I double checked, I went to the VMs main tab, selected a VM, then went to 
the permissions sub tab. Clicked add. The dialog that popped up looks like the 
one attached, which is what I was expecting. The one you attached appears to 
be missing some styling, which is likely what caused the Role to Assign part 
to be scrolled below the bottom of the page.

Can you complete clear your cache (not shift reload, but settings->clear 
cache). If that doesn't work can you tell us the version of the patternfly rpm 
installed on your engine?

Its highly likely the dropdown is there, but its scrolled below the bottom of 
the dialog and thus you can't see it. I thought I made sure all the dialogs 
were working, seems like I missed one. Let me check it out and see what is 
going on.

If you can consistently reproduce this problem can you do the following?

Installl the debug symbol maps doing this:

yum install ovirt-engine-webadmin-portal-debuginfo ovirt-engine-userportal-
debuginfo

Then reproduce the error and post the stack trace from the UI.log again. The 
one you are posting now is the obfuscated one which we can manually 
deobfuscate but its much easier when the symbols are installed.

Looks like a bug in the code to me, there are a couple of casts in
org.ovirt.engine.ui.uicommonweb.models.datacenters.DataCenterGuideModel.run(DataCenterGuideModel.java:1679)
that could be the culprit, can you open a bugzilla against the webadmin?

Yes, you will need to restart engine before the log starts showing a better

Okay, great now if you want to set that as the default, so you don't have to 
do that manually each time do the following:

ssh into the engine box as root.
engine-config -s ClientModeSpiceDefault=Plugin

That should default it to be plugin for all the VMs.

Looking at the code it also set the default mode to 'native' instead of 
plugin. After you set the flag to true and restarted the engine, do you see the 
'plugin' option when you right click on a running VM in webadmin and select 
console options? It should be under Console Invocation

Okay gotcha,
Note in 4.1 this ability will be completely removed, the bugzilla is for cases 
where 
people need it in some kind of production environment.

Assuming you can ssh into the machine that is running the engine (either HE or 
standard engine) as root:

engine-config -s EnableDeprecatedClientModeSpicePlugin=true

If that doesn't work because the option was not added to engine-config 
(couldn't tell 
from reading the code). Try this:

sudo su postgres
--this will log you in as the postgres user
psql -d engine
--this will start psql connecing to the engine database. The default will be
--engine if you didn't specify something else during engine-setup. psql -l
--will list all the databases.
update vdc_options set option_value=true where 
option_name='EnableDeprecatedClientModeSpicePlugin';

That bugzilla relates to the legacy spice.xpi FF plugin, and possibly some 
activex plugin for IE. The current way is the following:

1. Get virt-viewer for your platform.
2. Associated virt-viewer with .vv files in your browser.
3. Click the button, which will download the .vv file with the appropriate 
ticket.
4. The browser will launch virt-viewer with the .vv file as a parameter and it 
should just all work.

The label that has the dotted line under it should have a tooltip explaining 
the issue. But some of the most likely issues are:

1. DC is at 3.6 and you can't have 4.0 clusters in 3.6 DC.
2. Active host on 3.6 in the cluster. You can put the hosts in maintenance and 
upgrade the cluster, you will obviously also have to upgrade the hosts after 
that before you can activate them again.

Also to get a de-obfuscated stack trace in the UI.log please install the ui 
debug 
package:

yum install ovirt-engine-webadmin-portal-debuginfo 
ovirt-engine-userportal-debuginfo

Then recreate the issue and look in the UI.log again, it should
now at least give you a better readable stack trace.

I asked him, he said 3.6.5 and 4.0. So if your 3.6.5 is the same then it 
didn't solve your issue obviously. I am completely out of things to try or see 
that could possibly be the problem.

And we verified the ping between your browser machine and the engine was low. 
The load on the engine was near 0. That your browser was either Chrome/FF and 
that the machine running the browser is plenty powerful. 

Did you ever disable the repos besides the 3.6 one and run a yum update (on 
the engine)? Greg one of the other maintainers recently did some performance 
improvements, I just don't remember which version they go into. either 3.6.5 
or 3.6.6. If I remember correctly for some reason it takes a long time to get 
data from the engine to your browser, we just don't know why it takes so long 
as we profiled the engine running in your environment and that was all fine as 
well.

If you type engine-backup --help you will get a list and explanation of all 
the possible options. 

Affects only the custom dump format. Will not pass to pg_restore '--no-owner --
no-privileges'. Might not work as expected with the --*db-user options.

Is what the --help says, not sure what that means though.

It is highly likely 1 of 2 things:

1. The entropy mentioned by Brett, however that is mostly applicable on hosted 
engine as VMs don't usually have good entropy.
2. The engine cannot resolve itself (which looking at your description is the 
likely culprit). Since you don't have DNS, you need to add the fqdn to 
/etc/hosts so it can resolve itself.

I don't know which SDK you are using or if you are doing direct http requests 
with your own framework, but in order for non privileged users to use the REST 
api you need to pass the 'filter: true' header with the request. This will tell 
the REST api to filter the results based on the users permissions.

As far as I know we already force a redirect to https for anything that 
requires it. Basically the only pages that do not are the welcome page and 
some of error pages. But when you try to actually access anything like the web 
admin or user portal we force a redirect to https.

While I cannot answer your actual question as I don't know enough about the 
internal implementation of how oVirt interacts with gluster. I just want to 
point out major difference between oVirt and VMWare. In oVirt storage domains 
are attached to data centers, not hosts. So there is no does the disk move 
from host1 to host2. The disk is on the storage domain and host1 and host2 and 
every other host in the data center has access to the storage domain.

Looks like they already did that as the bottom stack trace has this in it:
org.ovirt.engine.ui.uicommonweb.models.storage.DisksAllocationModel.
$updateImageToDestinationDomainMap(DisksAllocationModel.java:288)

So looks like an issue in DiskAllocationModel.

I think a good starting point would be this:

https://www.ovirt.org/develop/release-management/features/storage/backup-restore-api-integration/

that is running your incremental backups from live snapshots made from running

Note this is BAD security practice, but you can use:

engine-config -s UserSessionTimeOutInterval=-1

engine-config -l will give you a list of things you can configure including a 
description of each option.

Note in 4.0 we have split groups and users, and you have to select which type 
you want to search for. This is to reduce the number of queries to the LDAP 
server.

Strange, can you post the output of the following two commands on the HOST?

vdsClient -s 0 getVdsCaps | grep -i flags

virsh -r capabilities

That should tells us what libvirt thinks the capabilities of the machine are.

IIRC this simply reports what cpu type the cluster is set to that the host is 
in. Looked up the Xeons you mention, and as far as I can tell that is a 
haswell no-TSX cpu. Simply select the cluster this host is in and switch the 
cpu type to haswell no-TSX. You should be able to deploy your VM then.

Re: [ovirt-users] Max amount of datacenters per ovirt engine

The reason I mentioned manage IQ is that it would give you one tool to manage 
everything. You would not have to do much (perhaps the initial setup) in the 
oVirt manager. After that everything goes through manage IQ. Since it is 
designed to manage the managers it is much more fault tolerant which appears 
to be one of your requirements.

As far as max number of data centers goes. I am not entirely sure to be 
honest. But I believe your proposed setup will push the engine beyond it 
limits. I would definitely go with multiple engine instances, maybe in zones 
where the connection to the hosts is better, and then something to control the 
engines from a central location (like manage IQ).
