AFAIK loopback mount an NFS share could lead to deadlocks:

Up to now the hosted-engine storage domain could simply contain the engine
VM so you need another data storage domain to act as the master storage
domain; when another storage domain is ready, the engine will automatically
import the hosted-engine SD and the engine VM.

ovirt-ha-agent systemd unit is not going to wait, by design, nfs-server so
it could start before the storage is available and this will cause an extra
delay due to retry on error.
A few minutes (3/4) should be considered acceptable.

[ovirt-users] no spm node in cluster and unable to start any vm or stopped storage domain

[Moritz Baumann]

Hi,
after an upgrade I get the following errors in the web gui:

VDSM ovirt-node01 command SpmStatusVDS failed: (13, 'Sanlock resource 
read failure', 'Permission denied')

VDSM ovirt-node03 command HSMGetAllTasksStatusesVDS failed: Not SPM

These messages happen from all nodes.

I can stop vms and migrate them but I cannot start any vm again

How do I get bet to a sane state where one node is SPM.

Best,
Moritz

Sandro, thank you for your reply.

I hadn't heard about kimchi before.  Virt-manager had been discounted as the 
user interface is not really friendly enough for non-technical people, which is 
important for us.  The simple web interface with oVirt, however, is excellent 
in this regard.

I would say that the primary use-case is this: We want a server which 
individual employees can log into (using their active directory logins), access 
company-wide "public" VMs or create their own private VMs for their own use (if 
permitted).  Users should be able to start and stop the "public" VMs but not be 
able to edit or delete them.  They should only have full control over the VMs 
that they create for themselves.  And very importantly, it should be possible 
to say which users have the ability to create their own VMs.  Nice to have 
would be the ability for users to be able to share their VMs with other users.  
Really nice to have would be a way of detecting whether VMs are in use by 
someone else before opening a console and stealing it away from the current 
user!  (Actually, case in point, the user web interface for oVirt 3.6 always 
starts a console for a VM when the user logs in, if it is the only one running 
on the server and which the user has access to.  I don't know i
 f this is fixed in 4.1, but our work-around is to have a dummy VM that always 
runs and displays a graphic with helpful text for any that see it!  Bit of a 
nuisance, but not too bad.  We never found a way to disable this behaviour.)

We started off some years ago with a server running oVirt 3.4, now running 3.6, 
with the all-in-one plugin and had good success with this.  The hosted engine 
for oVirt 4.1 seemed to be the recommended "upgrade path" -- although we did 
also start with entirely new server hardware.

Ultimately once this first server is set up we will want to convert the old 
server hardware to a second node so that we can balance the load (we have a 
number of very resource-hungry VMs).  This would be our secondary use-case.  
More nodes may follow in future.  However, we don't see the particular need to 
have VMs that migrate from node to node, and each node will most likely have 
its own storage domains for the VMs that run on it.  But to have one central 
web interface for managing the whole lot is a huge advantage.

Coming then to the storage issue that comes up in my original post, we are 
trying to install this first server platform, keeping the node, the hosted 
engine, and the storage all on one physical machine.  We don't (currently) want 
to set up a separate storage server, and don't really see the benefit of doing 
so.  Since my first email, I've actually succeeded in getting the engine to 
recognise the node's storage paths.  However, I'm not sure it really is the 
right way.  The solution I found was to create a third path, /srv/ovirt/engine, 
in addition to the data and iso paths.  The engine gets installed to 
/srv/ovirt/engine and then once the engine is started up, I create a new data 
domain at node:/srv/ovirt/data.  This then adds the new path as the master data 
domain, and then after thinking a bit to itself, suddenly the hosted_storage 
data domain appears, and after a bit more thinking, everything seems to get 
properly registered and works.  I can then also create the ISO storag
 e domain.

Does this seem like a viable solution, or have I achieved something "illegal"?

I am still not having much luck with my other problem(s) to do with restarting 
the server: it still hangs on shutdown and it still takes a very long time 
(about ten minutes) after the node starts for the engine to start.  Any help on 
this would be much appreciated.

Thanks
Andy

Sven,

This config value is hidden. You can update it by running:

su - postgres -c "psql engine -c "UPDATE vdc_options set option_value = '' where option_name = 'vdsHeartbeatInSeconds'""

Please note that the default value is 30 seconds.

and next you need to restart your engine.

Thanks,
Piotr

I think that you are looking for vdsHeartbeatInSeconds which specifies 
acceptable time of no activity.
You can increase it which would make it more resilient to network fluctuations.

Please note that it is part of the host life cycle and too big value would 
limit our ability to detect real network issues.

Thanks,

Re: [ovirt-users] Nested KVM for oVirt 4.1.2

[ovirt]

For now, it is just for me to learn.
If I like the solution, I will then build a POC with "real" hardware 
(which I already have).

Then I can deploy at my colo for clients.

Hi, so if I understood correctly, you're trying to work on a single host
deployment right?
Or are you just trying to replace the bare metal all-in-one 3.6 in a
context with more hosts?
If this is the case, can you share your use case? I'm asking because for
single host installations there are other solutions that may fit better
than oVirt, like virt-manager or kimchi (
https://github.com/kimchi-project/kimchi )

Sure, I was just wondering why you were running in nested virtualization :-)
Being your use case a "playground" environment, I can suggest you to have a
look at Lago http://lago.readthedocs.io/en/stable/
and at Lago demo at https://github.com/lago-project/lago-demo
to help you preparing an isolated test environment for your learning.

I have one CentOS7 host (physical) & 3x oVirt nodes 4.1.2 (these are
vm's).

Hi, can you please share the use case for this setup?

I have installed vdsm-hook-nestedvm on the host.

Should I install vdsm-hook-macspoof on the 3x node vm's?

It is, eventually, but if you do manage to build without it, then it's
a good step forward, and it most likely means you do need more memory.
I suggest opening a new thread about this specifically, perhaps even
one here (ask what developers are using) and one on infra (ask what CI
uses when building release builds).

If it turns out that at least some people use similar hardware without
problems, it might indeed be an issue specific to your environment -
kernel, swap etc configuration, jdk/jvm, etc.

If possible it might make sense to try an identical build on a centos7
VM just to see it's not a hardware problem (although I can't think of
anything that will trigger such a problem).

I guess most if not all developers simply use PREFIX that points at a
writable place - ~/my-ovirt-engine or something like that. That's
mentioned in the readme, and also in:

http://www.ovirt.org/develop/developer-guide/engine/engine-development-environment/

[ovirt-users] Ovirt Hosted-Engine VM iptables

[Andrew Dent]

Hi

I would like to add rules into the iptables of the Hosted Engine VM in 
Ovirt.
I am wanting to monitor the Ovirt Engine using Nagios -> NRPE and I 
would like to open port 5666


the version is oVirt Engine Version: 4.1.1.8-1.el7.centos
I have tried using the normal process for iptables (iptables-save etc), 
but it seems that the file

/etc/sysconfig/iptables
is ignored when the Ovirt Engine VM starts.

How can I add permanent iptables rules into the Engine VM?

Kind regards



Andrew

yes, this is a known issue. The fix depends on
https://bugzilla.redhat.com/show_bug.cgi?id=1332019 which will be available
only for oVirt 4.2 when we will able to consume it.

But in order to not to forget about it, could you please open a bug about
your issue?

What do you mean in "ignored"?

What's the output of 'iptables-save'?

Did you ask to configure the firewall during engine-setup?

>
> How can I add permanent iptables rules into the Engine VM?

On the engine vm (unlike hosts), the only thing that touches iptables
is engine-setup. Before doing that it asks you if you want to configure
the firewall. There aren't currently means to add your custom rules -
either you manage it all by yourself or you let engine-setup do that.

Alternatively, it's recommended to use firewalld. engine-setup can
add to firewalld the stuff it wants, and you still can add your own
stuff.

If I got you wrong and you refer to the hosts (not engine), see also:

https://www.ovirt.org/blog/2016/12/extension-iptables-rules-oVirt-hosts/

Re: [ovirt-users] Ovirt Hosted-Engine VM iptables

[Andrew Dent]

I can add a rule into ipdates such as this
iptables -I INPUT -s 192.168.0.10 -p tcp -m tcp --dport 5666 -j ACCEPT
I can see the addition has succeeded with this
iptables-save > /etc/sysconfig/iptables

But a reboot of the Engine VM (not the Host) doesn't keep the new rule, 
and I was expecting that during bootup CentOS would read from 
/etc/sysconfig/iptables.

Alas it isn't.

Found a solution.
After reading this
https://stackoverflow.com/questions/24756240/how-can-i-use-iptables-on-centos-7
I installed iptables-services
But once installed I found that iptables -L showed no rules.
thankfully I still had the default hosted-engine rules in 
/etc/sysconfig/iptables

iptables-restore < /etc/sysconfig/iptables
Then.
service iptables save
restored the default hosted-engine rules including my rule for 5666.

Rebooting the hosted-engine VM and my rule 5666 for NRPE is still there.
Success!!

To answer your other questions

> Did you ask to configure the firewall during engine-setup?
Yes.
Looks like it setup firewalld for me.

> Alternatively, it's recommended to use firewalld.
For the moment I have disabled firewalld and are using iptablesIs 
there a reason why firewalld is preferred over iptables?


Kind regards

 Hi

 I would like to add rules into the iptables of the Hosted Engine VM

 Ovirt.
 I am wanting to monitor the Ovirt Engine using Nagios -> NRPE and I 
would

 like to open port 5666

 the version is oVirt Engine Version: 4.1.1.8-1.el7.centos
 I have tried using the normal process for iptables (iptables-save 
etc), but

 it seems that the file
 /etc/sysconfig/iptables
 is ignored when the Ovirt Engine VM starts.


What do you mean in "ignored"?

What's the output of 'iptables-save'?

Did you ask to configure the firewall during engine-setup?



 How can I add permanent iptables rules into the Engine VM?


On the engine vm (unlike hosts), the only thing that touches iptables
is engine-setup. Before doing that it asks you if you want to configure
the firewall. There aren't currently means to add your custom rules -
either you manage it all by yourself or you let engine-setup do that.

Alternatively, it's recommended to use firewalld. engine-setup can
add to firewalld the stuff it wants, and you still can add your own
stuff.

If I got you wrong and you refer to the hosts (not engine), see also:

Best,



 Kind regards

Re: [ovirt-users] Nested KVM for oVirt 4.1.2

[ovirt]

Sandro,
If & when one decides to "graduate" & use real hardware, what is the 
install process?

Is the gluster part still automated or that has to be done manually?

Another question, what type of use cases & jobs is oVirt being deployed 
in & how are people getting tech support?

Sure, I was just wondering why you were running in nested
virtualization :-)
Being your use case a "playground" environment, I can suggest you to
have a look at Lago http://lago.readthedocs.io/en/stable/
and at Lago demo at https://github.com/lago-project/lago-demo
to help you preparing an isolated test environment for your learning.

I have one CentOS7 host (physical) & 3x oVirt nodes 4.1.2 (these are
vm's).

Hi, can you please share the use case for this setup?

I have installed vdsm-hook-nestedvm on the host.

Should I install vdsm-hook-macspoof on the 3x node vm's?

Re: [ovirt-users] GetStorageDeviceListVDS failed

[Sahina Bose]

I'm not an lvm expert, a quick search indicates either reboot or using
dmsetup to clear the entries

Alternately, you can check on https://www.redhat.com/archives/linux-lvm/ or
ask on the list.

[ovirt-users] Migrating VMs because previous host became non-operational

[Brett Holcomb]

I'm seeing this error "Migrating VM blah-blah because previous host 
became non-operational.  This appears in the WebUI under the task lists 
and is getting annoying since it disrupts things like creating snapshots.


This migration is quite a feat on a single hosted engine installation 
with only one host so what exactly is going  on?  I'd be glad to include 
some logs and have looked at the vdsm logs but have no idea what I'm 
looking form.
