I think that I got such case before (4.2) and the only way I managed to update 
the HE VM was to set the OVF update interval to 1 min and wait for an hour to 
pass.

Hi Didi,

There are three, unless there are more I am not aware:
Defined memory - which I am trying change
Max allowed - which was auto increased
Guaranteed - which was also auto changed, but I set it to 4096

There are different parameters around memory - are you sure you change
the correct one(s)?

Also adding Arik. Arik - please see the history of this thread. It
might be an issue in the engine, or in hosted-engine HA, or both - not
sure.

No idea. 4.3 is past EOL now. I suggest to try latest 4.4, and if it
reproduces, file a bug and attach all relevant logs (including engine,
vdsm, hosted-engine-ha).

[ovirt-users] Re: oVirt Engine increase RAM and CPU

2021-02-22 Thread Joseph Goldman 

Hi Marko,

 I have also had this problem on an oVirt 4.3 install - I could never 
fix it and have not tried to upgrade to 4.4 yet - my workaround for now 
(as you have deduced) is to just 'up' it while running so its hotswapped 
in - annoying, but I think the best way around this without upgrade 
would be to re-deploy the hosted engine defining the new resources using 
an engine-backup - but again this is just as scary as in-place upgrade 
lest you lock yourself out from your other running VMs in a production 
environment.


 I plan to do it - I just need some time to set it up in a lab so I 
know what to expect.


Thanks,
Joe

It looks like  should report a bug. But before I do that, we are

4.3 version?

But in UI, I still see

Defined Memory:
16384 MB


And the vm.conf on all three Hosts is still showing
smp=8   <= cpu increase is already updated
memSize=16384 <= but ram is still same


It looks like  should report a bug. But before I do that, we are currently on 
4.3.8.2 version – is this by any change fixed by latest 4.3 version?

Isn't there the setting in web admin gui where you select a storage domain,
three dots at top right and then "Update OVFs"?
Shouldn't it force the update? I see it in 4.3.11, also for the hosted
engine storage domain

[ovirt-users] Re: oVirt Engine increase RAM and CPU

2021-02-22 Thread Vrgotic, Marko 
Hi Didi,

I increased the RAM from 16 to 32 and change is instant on the VM, but as you 
have mentioned, it does not get written right away to VM image.
Upon reboot its back to 16GB RAM.


At this moment, change is applied, and I am waiting up to 60min to see if the 
changes will be written to survive reboot.

Regarding how to change it, the UI Edit seem to be the way. If I go with 
/var/run/… file changes fast, even with VM being shutdown.

@oVirt does anyone know how long it usually takes to have the change written to 
VM image?

Please note that I do not have any experience with this whatsoever.
Also for the further replies below. Just guessing. I suggest to try
first on a test system if it's about a production/critical system.

I guess that it will mark the VM as requiring a reboot for changes to
take effect, and that they'll actually be applied only on hard-reboot
(meaning, not just running 'reboot' from inside). So yes,
I guess the process should be:

1. Edit as needed
2. Perhaps wait a bit or something like that to make sure changes
reached OVF_STORE on the shared storage. No idea how. Perhaps we log
enough about this to existing logs, or perhaps you can dump the conf
to verify manually.
2. Set global maint, shutdown, clear global maint (and either

I have no idea other than the bugs I was personally involved with
(which you can find in bugzilla).
Perhaps RHV or oVirt docs have some guidelines, didn't check.
If not, then I suppose the guidelines are "Use the defaults and follow
recommendations", which mean:
1. Allocate 16GB RAM for the HE VM. Perhaps we even recommend more
than that for larger setups, not sure.
2. engine-setup then sets both min and max to 4GB (=25% of RAM).

If you do want to play with this, you should of course test thoroughly
and carefully :-).
Consider also other processes on the machine needing rather-large
amounts of memory, including DWH and PostgreSQL (which we also
automatically configure and which you can further refine if needed,
and also set up to run on separate machines).

That's a question for the JVM, not for oVirt :-). I suppose it will
simply use a constant size.

It should be, if you make sure other stuff (dwh+pg) do not use too
much, or you have also enough swap (but then do not expect good
performance if you actually run into actually using it).

Yes Bibi,

This is about prod system, 1200 VMs running.

Ok, I will test it first on staged engine.

Thank you.

Please note that I do not have any experience with this whatsoever.
Also for the further replies below. Just guessing. I suggest to try
first on a test system if it's about a production/critical system.

I guess that it will mark the VM as requiring a reboot for changes to
take effect, and that they'll actually be applied only on hard-reboot
(meaning, not just running 'reboot' from inside). So yes,
I guess the process should be:

1. Edit as needed
2. Perhaps wait a bit or something like that to make sure changes
reached OVF_STORE on the shared storage. No idea how. Perhaps we log
enough about this to existing logs, or perhaps you can dump the conf
to verify manually.
2. Set global maint, shutdown, clear global maint (and either
immediately start the vm or let ha-agent do this for you).

Hi Didi,

Just to be sure,  considering its an HA instance, I need to set to 
maintenance=global and execute these changes – CPU increase will most likely 
require reboot?

For the HEAP changes, I have been doing that lot on the Atlassian instances, 
just not sure how oVirt-engine  is going to react and if there are any 
guidelines I should stick to in ovirt  case.
I.e. What if I set min and max to same value?
Is it going to be “ok” if I assign more than half of system RAM to the JAVA? 
Ect…

Did you try to simply edit the vm from the admin ui? This should be

You can control the values passed as -Xms and -Xmx using the config
values ENGINE_HEAP_MIN and ENGINE_HEAP_MAX.

They are set by engine-setup on initial setup but not changed later.
It writes /etc/ovirt-engine/engine.conf.d/10-setup-java.conf .
It's probably safer to create your own file for overriding, e.g.
99-my-setup-java.conf or something.

There have been various relevant changes to this over the years, you
can search bugzilla for 'ENGINE_HEAP_MIN' to find them.
