[ovirt-users] Using VDSM to edit management interface

[Kirin van der Veer]

Hi oVirt people,
I have setup a new cluster consisting of many oVirt Nodes with a single
dedicated oVirt Engine machine.
For the most part things are working, however despite entering the DNS
search domain during install on the Nodes the management interface is not
aware of my search domain and it has not been added to /etc/resolv.conf
(perhaps that is unnecessary?).
I eventually worked out that the DNS search domain should be included in
/etc/sysconfig/network-scripts/ifcfg-ovirtmgmt
However as per the header/warning, that file is generated by VDSM.
I assumed that I should be able to edit the search domain with vdsClient,
but when I run "vdsClient -m" I don't see any options related to network
config.
I found the following page on DNS config:
https://www.ovirt.org/develop/release-management/features/network/allowExplicitDnsConfiguration/
But it does not seem to offer a way of specifying the DNS search domain
(other than perhaps directly editing /etc/resolv.conf - which is
generated/managed by Network Manager).
nmcli reports that all of my interfaces (including ovirtmgmt) are
"unmanaged". Indeed when I attempt to run nmtui there is nothing listed to
configure.
This should be really simple! I just want to add my local search domain so
I can use the short name for my NFS server. I'd appreciate any advice.

Thanks in advance,
Kirin.

Hi,

Seems the communication with the host is slow and you get a timeout error.
Is there a chance you opened the SetupNetwoks dialog while installing the host 
(it may slow down the host since it queries the host for lldp information)?
Please try to re-install (or remove and re-add) the host (don't open the setup 
network dialog during the installation).
More technically, there is a bug in the code -Collecting and persisting the 
data from the host is done inside a transaction.Only the persisting should be 
done in a transaction.According to the attached log seems the collection of the 
data from the host finished successfully (was slow, but finished without a 
timeout), but the persistence of the data fails since during the persistence 
the transaction reached to the timeout.
Can you please file a bug in the bugzilla and attach the relevant logs 
(engine.log, server.log and vdsm.log)
Thanks.Alona.

How exactly? Storage profiles is not present for external providers - so 
lack of this feature.


For now only way to do that is vdsm hook.

Re: [ovirt-users] ovirt 4.2.2-rc3 switching from legacy to OVS..

[Thomas Davis]

Well, I just hit

https://bugzilla.redhat.com/show_bug.cgi?id=1513991

And it's been closed, which means with vdsm-4.20.17-1.el7.centos.x86_64
 OVS networking is totally borked..

I know OVS is Experimental, but it worked in 4.1.x, and now we have to 
do a step back to legacy bridge just to use 4.2.x, which in a vlan 
environment just wreaks havoc (every VLAN need's a unique mac assigned 
to the bridge, which vdsm does not do, so suddenly you get the kernel 
complaining about seeing it's mac address several times.)


There is zero documentation on how to use OVN instead of OVS.

OVS switch support is experimental at this stage and in some cases
when trying to change from one switch to the other, it fails.
It was also not checked against a hosted engine setup, which handles
networking a bit differently for the management network (ovirtmgmt).
Nevertheless, we are interested in understanding all the problems
that exists today, so if you can, please share the supervdsm log, it
has the interesting networking traces.

We plan to block cluster switch editing until these problems are
resolved. It will be only allowed to define a new cluster as OVS,
not convert an existing one from Linux Bridge to OVS.

I did the installation with windows 7 and i have installed the 
ovirt-tools-setup via the iso and everything is OK.

The simple way is to install ovirt-guest-tools-iso on the hosted-engine and 
then get the iso to put on your ISO domain.
After that just put this iso on the cdrom of the windows 7 VM and execute 
ovirt-guest-tools-setup.

postgres=# CREATE EXTENSION "uuid-ossp”;

BTW, this yelds error:

Please upgrade. We have solved issues and improved performance and scale
substantially since 3.6.
You may also wish to apply lvm filters.
Y.


Oh, we know and are looking at what we'll have to do to upgrade.  With that 
said, is there more information on what you mentioned as "lvm filters" posted 
somewhere?


Also, would VM reduction, and IMHO, virtual disk reduction help this problem?

Is there and engine config parameters that might help as well?

Thanks for any help on this.

It appears to me it already does that, this a screenshot of me putting in a

Hi,

Seems the communication with the host is slow and you get a timeout error.
Is there a chance you opened the SetupNetwoks dialog while installing the host 
(it may slow down the host since it queries the host for lldp information)?
Please try to re-install (or remove and re-add) the host (don't open the setup 
network dialog during the installation).
More technically, there is a bug in the code -Collecting and persisting the 
data from the host is done inside a transaction.Only the persisting should be 
done in a transaction.According to the attached log seems the collection of the 
data from the host finished successfully (was slow, but finished without a 
timeout), but the persistence of the data fails since during the persistence 
the transaction reached to the timeout.
Can you please file a bug in the bugzilla and attach the relevant logs 
(engine.log, server.log and vdsm.log)
Thanks.Alona.

Hi,Alona thanks for your reply, I find node network is not fixed, there is not 
Bridge ovirtmgmt.
 I solve this issue, as shown in the figure. ovirtmgmt is not in "Assiged 
Logical Networks",  I drag ovirtmgmt to "Assiged Logical Networks" .then click 
OK. host`s status become up, this is work.

But when add host , network setup fail, host is "no reponsed" .

[ovirt-users] NFS 4.1 support and migration

[spfma . tech]

Hi,
   Is NFS 4.1 supported and working flawlessly in oVirt ? I would like to 
give it a try (performances with // transferts), but as it requires changes in 
my network design if I want to add new links, I want to be sure it worth the 
effort.   Is there an easy way to "migrate"a NFS3 datastore to a NFS4.1 one 
? Options are greyed when the domain is up, so maybe it requires more care than 
just a simple click.

[ovirt-users] Query about running ovirt-4.2.1 engine support 3.x nodes ?

[Joseph Kelly]

Hello All,


I have two hopefully easy questions regarding an ovirt-4.2.1 engine support and 
3.x nodes ?


1) Does an ovirt-4.2.x engine support 3.x nodes ? As This page states:


"The cluster compatibility is set according to the version of the least capable 
host operating system in the cluster."


https://www.ovirt.org/documentation/upgrade-guide/chap-Post-Upgrade_Tasks/


Which seems to indicate that you can run say a 4.2.1 engine with lower version 
nodes, but is that correct ?


2) And can you just upgrade the nodes directly from 3.x to 4.2.x as per these 
steps ?


1. Move the node to maintenance
2. Add 4.2.x repos
3. yum update
4. reboot
5. Activate (exit maintenance)


I've looked in the release notes but wasn't able to find much detail on 
ovirt-nodes upgrades.


Thanks,

Joe.

[ovirt-users] How to log-on to a VM from Centos atomic template

[Niv Gal Weizer]

On Ovirt 4.2:
- click on the left Storage tab
- click on Domains
- choose Centos 7 Automic Host imge v1711 for X86_64 , and clic import
- enable the Import as Template
- Click OK

Now use this template to create a new VM.
After this VM is created run it and open a console to it.


-How to log in to this VM?
There is no way to change the password from the VM create menu, or change
the password after it was created.

Re: [ovirt-users] Quick question about oVirt 3.6 and vdsm log in DEBUG mode (apprently by default??)

We're running oVirt 3.6 on 9 Dell Blades but with just two fairly fat

115 VMs or thereabouts

I'm thinking that vdsm having DEBUG enabled isn't helping the latency, but
as far as I know it came this way be default.  Can we safely disable DEBUG
on the hypervisor hosts for vdsm?  Can we do this while things are roughly
in a steady state?  Remember, just doing the moves could throw everything
into vdsm la-la-land (actually, that might not be true, might take a new
storage thing to do that).

Just thinking out loud... can we safely turn off DEBUG logging on the
vdsms? Can we do this "live" through bouncing of the vdsm if everything is
"steady state"?  Do you think this might help the problems we're having
with storage operations? (I can see all the blades logging in iSCSI wise,
but ovirt engine does the whole red triangle connecting thing, for many,
many, many hours).
