Re: [ovirt-users] API endpoint for a VM to fetch metadata about itself

[Geoff Sweet]

OK, that's a great place for me to start. However the problem is that all
my post-install tooling is now running on a VM that knows nothing about
itself (having been installed via pxe and kickstart) like it's {vm_id}.
Can the API be used to query for a VM and it's attributes based on
something like a MAC address or the IP itself?

Do you think there a solution ?


Obviously this a bit more "chicken-and-egg" than running a hosted 
engine.  Even if there was a "start automatically" sort of thing, this 
is still going to be fraught with potential issues, because almost 
anything could happen to prevent the "router vm" from starting.


I think you've created a fairly high risk scenario.

In other words, even if you got this working, I wouldn't trust it.

Just my opinion.  At a minimum I'd pull the "router" out of the VM 
stack.  Now, you could have a separate hypervisor cluster stack for the 
router, just don't put it's mgmt engine (separate engine req'd) behind 
the router :-)





Sincerely,

Fabrice

The engine needs to be able to see + manage the node. You'll have to

the engine can control the node.


Once the node's in control, the engine can restore the VM when it

Re: [ovirt-users] Hosted Engine VM not imported

[Alessandro De Salvo]

Ciao Simone,

many thanks. So, how are we supposed to use those hooks? Should we just 
create a file 
/usr/share/ovirt-hosted-engine-setup/ansible/hooks/enginevm_before_engine_setup/enginevm_before_engine_setup.yml 
with the instructions to restore? Do you have an example for doing that?


For the moment I think I'll stick to the old procedure by calling 
--noansible, as you suggest.


I think the documenttation should be updated anyways, at least to add 
the --he-remove-storage-vm and --he-remove-hosts options, as well as the 
new procedure and the override with --noansible. Also, wouldn't it be 
safer to stick to the old procedure until the new one is fully 
operational? Or maybe at least a warning to the user, otherwise no one 
will ever be able to restorage a db and have it all functional with the 
default options.


Thanks,


    Alessandro

I didn't find a way to add other hosted engine nodes if the HE VM
is not imported in the cluster, like we were used in the past with
the CLI using hosted-engine --deploy on multiple hosts.


Ciao Alessandro,
with 4.2.1 we introduced a new deployment flow for hosted-engine based 
on ansible.
In this new flow we run a local VM with a running engine and we use 
that engine to create a storage domain and a VM there.
At the end we shutdown the locally running engine and we move it's 
disk over the disk of the VM created by the engine on the shared 
storage. At this point we don't need anymore the autoimport process 
since the engine migrated there already contains the engine VM and its 
storage domain.


We have an RFE, for this new flow, to add a mechanism to inject an 
existing engine backup to be automatically restored before executing 
engine-setup for migration/disaster-recovery scenarios.
Unfortunately it's still not ready but we have an hook mechanism to 
have hosted-engine-setup executing custom ansible tasks before running 
engine setup; we have an example 
in /usr/share/ovirt-hosted-engine-setup/ansible/hooks/enginevm_before_engine_setup/enginevm_before_engine_setup.yml.example


Otherwise the old flow is still there, you have just to add 
--noansible and everything should work as in the past.



Thanks for any help,

[ovirt-users] ovirt 4.1 - skylake - no avx512 support in virtual machines

[Marco Lorenzo Crociani]

Hi,
I can't access avx512* instruction set from virtual machines.
I have made a one server compute cluster to test new hardware:

oVirt 4.1.9
CentOS 7
Cluster CPU Type: Intel Skylake Family
Compatibility Version: 4.1

HOST:
CPU Model Name:Intel(R) Xeon(R) Platinum 8180 CPU @ 2.50GHz
Family: Family
CPU Type: Intel Skylake Family

Virtual Machine settings
A) VM:
Custom CPU Type: Use cluster default(Intel Skylake Family)
General Tab shows: Guest CPU Type: Skylake-Client

avx512: NO

B) VM:
Custom CPU Type: Skylake-Client
General Tab shows: Guest CPU Type: Skylake-Client

avx512: NO

C) VM:
Custom CPU Type: Use cluster default(Intel Skylake Family) [grey - 
cannot modify]

Migration mode: Do not allow migration
Pass-Through Host CPU
General Tab shows: Guest CPU Type: Skylake-Client

avx512: YES   ( cat /proc/cpuinfo  |grep avx512: avx512f avx512dq 
avx512cd avx512bw avx512vl )


Using pass-through host cpu (disabling vm migration) is the only way to 
access avx512 in a VM, is it a bug or am I missing something?

Hi,

you may have hit this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1542117

it could affect all VMs started with Engine <= 4.1 and later imported in
4.2, or Hosted Engine.

If your VM was first created under oVirt 4.2, please file a new bug.

HTH,

The standard way to have HA for oVirt engine is to set it up as a
self-hosted-engine and have more than one host in the hosted-engine
cluster.

We do know that there are people doing HA using other means, based on external
HA software (heartbeat), but that's more expensive (in hardware, work,
and perhaps software, depends on what you use) - I'd suggest doing that
only if your organization already has in-house expertise and experience
with such software.

Good luck and best regards,

No, but you can either cluster the engine in an HA cluster, run backup
frequently (I've had environments where I did an engine dump every hour
without any issues), or use self hosted engine, which is basically the
engine as a VM, so if a host goes down, it gets started on another. What
you cannot do is have multiple engines load-balancing the work, like
openstack controllers for example.

If the engine goes down, the hosts and VMs keep working, so you have time
to restore from backup or fix the engine without outages, besides a
management outage of course. If you are running hosted engine, it will
simply get started on another eligible host.

[ovirt-users] Before migrating to Ovirt

[Tal Bar-Or]

Hello Ovirt users,

Currently we haveing 4 Xen pools in our organization each pool have 8
servers.
Due to new 7.3 version change ,we plan to migrate our upcoming 5th pool to
Ovirt, the decision to do POC migration to Ovirt is from lots of Xen users
that suggested Ovirt migration better and  mature product migrate to it.

I started to test Ovirt currently only with one server with engine
installed, my question regarding Ovirt sine i am really newbie with that
system , is , is it possible to have multiple engine on it ?
What happen if the engine server crash with some reason? can i load it on
another cluster server?
Please advice

Thanks

Re: [ovirt-users] VM is locked, servlet , and SpiceVersion.txt problem

[Terry hey]

Thank for your reply.
OK, then do you know how to delete the lock virtual machine?
Because i cannot find the locked VM by using  "./unlock_entity.sh". I
cannot do anything on it.
Thank you.

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.

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

[Zip]

Thanks Alexander,

This works:

api.addMainTab('oVirtTab', 'ovirt-tab', ‘http://www.something.com',
{priority: 5});

Can you advise how to get the api.addSubTab to work?

api.addSubTab('ovirt-tab', 'Test 123', 'test-123', '#’);

I tried the above and many other combinations, no errors, just doesnt work.
Maybe I am wrong on what it does?

I am looking to add a submenu – same as the current 4.2.1 UI shows Network
and then(Vnic Profiles) (Networks) as submenus.

Thanks

Zip

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.

​Please take a look at below RFE introducing firewalld support for host and
blog post to read about new possibilities to customize host-deploy process
(which also can be used for custom firewalld rules) in oVirt 4.2:

On my hosts, I can see in my hosts that /etc/sysconfig/iptables does contain
the correct custom rules I added, but when manually checking with iptables
-L, I don't see my rules active.

On my hosts, I see that the iptables services is stopped and disabled, and
that the firewalld service is up and running.

That explains why iptables customization has no effect.


Indeed.

IIRC the type of firewall is now set per cluster or something like that, not
sure about the details - adding Ondra.


Per cluster, one can indeed choose the firewall type.
I suppose it translates on the hosts into the activation of the adequate 
service.

But how do we add custom rules in case of firewalld type?

On the hosts, I imagine that could translate into changes in :
/etc/firewalld/zones/public.xml

I'm trying to reproduce your steps, for understanding better was is the

Can you please attach it?

Indeed.

IIRC the type of firewall is now set per cluster or something like that, not
sure about the details - adding Ondra.

Only the engine.

So you should reply 'No' as you did in 'engine-setup', and handle
iptables/firewalld
on the engine after it's set up (upgraded), I think from the ui.

No, they are unrelated.

Hi Lionel,

The error message you've mentioned sounds like a UI error.
Can you please attach your ui log?

Also, on the data from 'images' table you've uploaded, can you describe
which line is the relevant disk?

Finally (for now), in case the snapshot was deleted, can you please
validate it by viewing the output of:
$ select * from snapshots;

[ovirt-users] Hosts firewall custom setup

[Nicolas Ecarnot]

Hello,

On oVirt 4.2.1.7, I'm trying to setup custom iptables rules as I'm doing 
since years with engine-config --set IPTablesConfigSiteCustom="blah blah 
blah".


On my hosts, I can see in my hosts that /etc/sysconfig/iptables does 
contain the correct custom rules I added, but when manually checking 
with iptables -L, I don't see my rules active.


On my hosts, I see that the iptables services is stopped and disabled, 
and that the firewalld service is up and running.


That explains why iptables customization has no effect.

In the engine setup, I see that 
/etc/ovirt-engine-setup.conf.d/20-setup-ovirt-post.conf contains :

OVESETUP_CONFIG/firewallManager=none:None

I'm confused about this setting : when running engine-setup, I'm not 
sure to understand if answering yes to the question about the firewall 
will modify the engine, the hosts, or all of them?


Actually, I'd like my engine to stay with a disabled firewall, but my 
hosts with an active one.


Is it true to say that this is not an option and I have to answer yes, 
enable the firewall on the engine, allowing the 
OVESETUP_CONFIG/firewallManager option to be set up (to firewalld or 
iptables), thus allowing the spread of this setup towards the hosts?


Thank you.

The host itself may be fine, but libvirt/QEMU running there may expose
problems, perhaps just for some VMs.  According to your logs something
is not behaving as expected on the source host during the faulty
migration.

> How ca I enable this libvirt debug mode ?

Set the following options in /etc/libvirt/libvirtd.conf (look for
examples in comments there)

- log_level=1
- log_outputs="1:file:/var/log/libvirt/libvirtd.log"

and restart libvirt.  Then /var/log/libvirt/libvirtd.log should contain
the log.  It will be huge, so I suggest to enable it only for the time
of reproducing the problem.

I don't know, but please remember there's both latency and throughput, both
of which are somewhat affected. Throughput will benefit from jumbo frames,
for example. Unfortunately it may affect latency a bit.
There was an interesting patch that if the NFS was local, bypassed the
NFS[1]. It was never completed and merged.
Lastly, chapter 6 at hyper-converged guide (should be available in few
hours) might be an interesting idea for you to consider - a single Gluster
that can later expand.

Re: [ovirt-users] Can't move/copy VM disks between Data Centers

[Andrei Verovski]

Hi,

Thanks for clarification. I’m using 4.2.
Anyway, I have to define another data center with shared storage domain (since 
data center with local storage domain can have only 1 host), and the do what 
you have described.

Is it possible to copy VM disks from 1 data center #1 local storage domain to 
another data center #2 NFS storage domain, or need to use export storage domain 
?

[ovirt-users] Q: VM disk speed penalty NFS vs Local data center storage

[Andrei Verovski]

Hi,

Since oVirt doesn’t support more then 1 host in data center with local storage 
domain as described here:
http://lists.ovirt.org/pipermail/users/2018-January/086118.html 


I have to setup NFS server on node with VMs (on same node) access via NFS.
10 GB shared storage is in the future plans yet right now have only 2 nodes 
with local RAID on each.

Q: What is VM disk speed penalty (approx %)  NFS vs Local RAID in oVirt data 
center storage? 
Currently I have 2 VMs running our accounting/inventory control system which 
are critical to storage performance limits.
2 other VMs have very low disk activity.

Thanks in advance

Re: [ovirt-users] Can't move/copy VM disks between Data Centers

[Fred Rolland]

Hi,
Which version are you using?

in 4.1 , the support of adding shared storage to local DC was added [1].
You can copy/move disks to the shared storage domain, then detach the SD
and attach to another DC.

In any case, you wont be able to live migrate VMs from the local DC, it is
not supported.

Fred

Re: [ovirt-users] VMs with multiple vdisks don't migrate

[fsoyer]

Hi,
I don't beleive that this is relatd to a host, tests have been done from victor 
source to ginger dest and ginger to victor. I don't see problems on storage 
(gluster 3.12 native managed by ovirt), when VMs with a uniq disk from 20 to 
250G migrate without error in some seconds and with no downtime.
How ca I enable this libvirt debug mode ?

Indeed, it's not related.

The error in vdsm_victor.log just means that the info gathering call
tries to access libvirt domain before the incoming migration is
completed. It's ugly but harmless.

It seems there is something wrong on (at least) the source host. There
are no migration progress messages in the vdsm_ginger.log and there are
warnings about stale stat samples. That looks like problems with
calling libvirt – slow and/or stuck calls, maybe due to storage
problems. The possibly faulty second disk could cause that.

libvirt debug logs could tell us whether that is indeed the problem and
whether it is caused by storage or something else.

 ​We don't have any hardware with iLO5 available, but there is a good
 chance that it will be compatible with iLO4. Have you tried to setup your

 option in Power Management.

​According to [1] those servers should support IPMI, so you could try
ipmilan fence agent and most probably try to add lanplus=1 into Options
field of an agent. If it doesn't work as expected, could you please try to
execute below commands and share the output?

fence_ipmilan -a  -l  -p  -P -vvv
-o status

Thanks

[ovirt-users] VMs stuck in migrating state

[nicolas]

Hi,

We're running 4.1.9 and during the weekend we had a storage issue that 
seemed to leave some hosts in an strange state. One of the hosts has 
almost all VMs migrating (although it seems to not actually being 
migrating them) and the migration state cannot be cancelled.


When clicking on one of those machines and selecting 'Cancel migration', 
in the ovirt-engine log I see:


2018-02-26 08:52:07,588Z INFO  
[org.ovirt.engine.core.vdsbroker.vdsbroker.CancelMigrateVDSCommand]

vmId='26d37e43-32e2-4e55-9c1e-1438518d5021'})' execution failed: 
VDSGenericException: VDSErrorException: Failed to CancelMigrateVDS, 
error = Migration process cancelled, code = 82


On the vdsm side I see:

2018-02-26 08:56:19,396+ INFO  (jsonrpc/0) [vdsm.api] START 
migrateCancel() from=:::10.X.X.X,54654,

2018-02-26 08:56:19,398+ INFO  (jsonrpc/0) [vdsm.api] FINISH

flow_id=874d36d7-63f5-4b71-8a4d-6d9f3ec65858 (api:52)


So no error on the vdsm side log.

I already tried restarting ovirt-engine but it didn't work.

Could someone shed some light on how to cancel the migration status for 
these machines? All of them seem to be running on the same host.


Thanks.
