[ovirt-users] Install oVirt node without Internet repository

[G, Maghesh Kumar (Nokia - IN/Bangalore)]

Hi


Description of problem:

Cannot add host - install fails & Install oVirt node without Internet repository



Version: Ovirt-4.2

Host is installed with RHEL 7.4



Actual results:

Host KVM02 installation failed. Command returned failure code 1 during SSH 
session 'root@192.175.2.231'

I found that right now on my oVirt Nodes in my test environment does not NOT 
connect to the internet...
Basically, i need the offline repository to access from oVirt nodes without 
Internet access.

Please guide us how to proceed

Regards,
Maghesh

[ovirt-users] Engine reports

[Anantha Raghava]

Hi,

I see that oVirt DWH is installed with Version 4.2.x. Now, how do I take 
the reports? I version 3.5, we had Jasper reports module using which we 
could take utilization reports. Can we do something similar here?

Thanks & Regards,

Same thing, the engine in this case is "self-hosted", as in, it runs in a VM 
hosted on the cluster that it is managing.  I am a beginner here, but from my 
understanding, each node is always checking on the health of the engine VM.  If 
the engine is missing (ie, the host running it has gone down), then another 
available, healthy host will spawn up the engine and you will regain access. 
In my experience this has worked very reliably.  I have 2 hosts, both are 
"able" to run the engine VM.  If I take one host down, I am not able to load 
the engine GUI.  But if I wait a few minutes, then I regain access, and see 
that the engine is now running on the remaining healthy host. Vincent

If your node running self-hosted engine crashes, the hosted engine will be 
started up on another node. It just takes a few minutes for this all to happen, 
but it works reliably in my experience.

First issue with fencing is solved per an earlier reply.

Second issue has also been solved earlier the way you outlined but I'm 
wondering why oVirt can't use br0 as the ovirtmgmt interface instead? 
What specific settings on br0 does it NOT like?  Is there any provision 
or flexibility to allow for custom defined bridges with oVirt?


I stumbled upon this page:

https://www.ovirt.org/documentation/how-to/networking/bonding-vlan-bridge/

and tried it but oVirt would have none of it.

After I let oVirt setup it's own bridges, I can see the settings it used 
(below) but wondering what *specific* settings in the network scripts 
does it not like?


Would like to know what we can and can't touch in the config files if we 
need to tweak the setup in higher level environments.


Cheers,

Hi,

you need a second host so as power management to work.
Since you verified it with command line then adding a second host should 
resolve this issue.


In regards to the interface, you need to remove the bridge interface as 
instructed (make it a simple interface) then leave ovirt to configure it 
ovirtmgmt bridge.

Hey Guy's,

I've tested my ILO2 fence from the ovirt engine CLI and that works:

fence_ilo2 -a 192.168.0.37 -l  --password=""
--ssl-insecure --tls1.0 -v -o status

The UI gives me:

Test failed: Failed to run fence status-check on host
'ph-host01.my.dom'.  No other host was available to serve as proxy
for the operation.

Going to add a second host in a bit but anyway to get this working
with just one host?  I'm just adding the one host to oVirt for some
POC we are doing atm but the UI forces me to adjust Power Management
settings before proceeding.

Re: [ovirt-users] Issues with ZFS volume creation

[Darrell Budic]

Try it with —force, if the disks have any kind of partition table on them, zfs 
will not allow you to over-write them by default.

If it’s still complaining about the disks being in use, it’s probably 
mutlipathd grabbing them. multipath -l or multipath -ll will show the to you. 
You may be able to get the pool creation done by doing ‘multipath -f’ to clear 
the ables and creating the pool before multipathd grabs the disks again, or you 
may want to read up on mutlipathd and edit your configs to prevent it from 
grabbing the disks you’re trying to use (or configure it for mutipath access to 
said disk, if you have the hardware for it).

[ovirt-users] hosted-engine Debug Help

[RabidCicada]

Heyo everyone.  I'm trying to debug hosted-engine --deploy.  It is failing
in `Copy configuration archive to storage` in `create_target_vm.yml`
from `hosted-engine
--deploy`.  My general and most important query here is how to get good
debug output from ansible through hosted-engine.  I'm running hosted-engine
through an ssh session.

I can't figure out how to get good debug output from ansible within that
workflow.  I see it's running through otopi, I tried setting typical
`debugger: on_failed` hooks etc and tried many incantations on the command line
and config files to get ansible to help me out.  The debugger: directive
and other debugger related ansible config file stuff wouldn't result in any
debugger popping up.  I also can't seem to pass normal - flags to
hosted-engine either and get it to ansible.  Ultimately I tried to use a
`pause` directive and it complained that it was in a non-interactive
shell.  I figured it might be the result of my ssh session so I enabled tty
allocation with -t -t.  It did not resolve the issue.

I eventually wrote-my-own/stole a callback_plugin that checks an
environmental variable and enables `display.verbosity = int(v)` since I
can't seem to pass typical - stuff to ansible through `hosted-engine
--deploy`.  It give me the best info that I have so far.   But it wont give
me enough to debug issues around Gathering Facts or what looks like a
sudo/permission problem in `Copy configuration archive to storage` in
`create_target_vm.yml`.  I took and used the exact command that they use
manually and it works when I run it manually (But I can't get debug output
to show me the exact sudo command being executed), hence my interest in
passing - or equivalent to ansible through `hosted-engine`.  I
intentionally disabled the VM_directory cleanup so that I could execute the
same stuff.

Soafter all that...what is a good way to get deep debug info from
hosted-engine ansible stuff?

Or does anyone have intuition for the possible sudo problem?

The easiest suggestion would be to move away from NFS. While NFS can be
made highly available (using pNFS and friends) and it's not that easy (nor
intuitive from oVirt).
iSCSI or FC are much better suited for the task, with multipathing and
iSCSI bonding (poor choice of terminology here).

You would need to use bonding (this time network bonding) and
highly-available NFS server (with a floating IP between the nodes most
likely) to succeed.

Re: [ovirt-users] SR-IOV and oVirt

[Michael Burman]

Hi Joe,

First of all, if you using the SR-IOV feature, you should use it only as
pci-passthrough vNICs only. Not as host-devices.
Our documentation is correct and is says : "adding a Network Interface with
type PCI Passthrough"

When enabling VFs on the host level, the expected MAC address for the VFs
is 02:00:00:00:00:01 and that is the correct behaviour.
Once you will create a network with 'passthrough' vNIC profile and then add
this as a vNIC to the guest VM, once the guest will run, you will see that
each pci-passthrough vNIC got it's own unique MAC address. No matter how
much VFs you are using, each pci-passthrough vNIC will get it's own MAC
address.

For vlan, you can create the network(passthrough) with the desired vlan tag
and it will be passed to the guest on run VM.

Cheers)

Re: [ovirt-users] ILO2 Fencing

[Alex K]

Hi,

you need a second host so as power management to work.
Since you verified it with command line then adding a second host should
resolve this issue.

In regards to the interface, you need to remove the bridge interface as
instructed (make it a simple interface) then leave ovirt to configure it
ovirtmgmt bridge.

[ovirt-users] Issues with ZFS volume creation

[Tal Bar-Or]

Hello All,
I know this question is might be out of Ovirt scope, but I don't have
anywhere else to ask for this issue (ZFS users mailing doesn't work), so I
am trying my luck here anyway
so the issues go as follows :

Installed ZFS on top of CentOs 7.4 with Ovirt 4.2 , on physical Dell R720
with 15 sas  10 k 1.2TB each attached to PERC H310 adapter, disks are
configured to non-raid, all went OK, but when I am trying to create new zfs
pool using the following command:


> zpool create -m none -o ashift=12 zvol raidz2 sda sdb sdc sdd sde sdf sdg
> sdh sdi sdj sdk sdl sdm
>
I get the following error below:

> /dev/sda is in use and contains a unknown filesystem.
> /dev/sdb is in use and contains a unknown filesystem.
> /dev/sdc is in use and contains a unknown filesystem.
> /dev/sdd is in use and contains a unknown filesystem.

When typing command lsblk I get the following output below, all seems ok,
any idea what could be wrong?
Please advice

[ovirt-users] ILO2 Fencing

[TomK]

Hey Guy's,

I've tested my ILO2 fence from the ovirt engine CLI and that works:

fence_ilo2 -a 192.168.0.37 -l  --password="" 
--ssl-insecure --tls1.0 -v -o status


The UI gives me:

Test failed: Failed to run fence status-check on host 
'ph-host01.my.dom'.  No other host was available to serve as proxy for 
the operation.


Going to add a second host in a bit but anyway to get this working with 
just one host?  I'm just adding the one host to oVirt for some POC we 
are doing atm but the UI forces me to adjust Power Management settings 
before proceeding.


Also:

[TomK]

Hey All,

Wondering if anyone see this happen and can provide some hints.

After numerous failed attempts to add a physical host to an oVirt VM 
engine that already had a gluster volume, I get this errors and I'm 
unable to start up gluster anymore:

[ovirt-users] SR-IOV and oVirt

[joe.paolicelli]

I am working with a customer on enabling sriov within oVirt and were noticing a 
couple of issues.

  1.  Whenever we assign the Number of VFs to a physical adapter in one of our 
hosts, it seems to set the mac addresses of each of the VFs to something other 
than all zeros.  Ex. 02:00:00:00:00:01
  2.  The above behavior seems to create duplicate mac addresses when we assign 
2 or more VFs to a guest VM.  All zeros will tell the guest VM that it needs to 
set the mac.  If the guest vm sees something other than all zeros, it will 
think that it was administratively assigned already and leave as is.
  3.  We were expecting oVirt to set all of the MAC addresses of the VFs 
initially to all zeros.  Then when we assign these VFs to the guest VM, the 
guest VM will assign a unique MAC to each of the VFs.
  4.  Please note that we are assigning the VF to the guest VM by adding a Host 
Device (the specific pci host device for the VF).  This seems to be different 
than your docs which shows adding a Network Interface with type PCI Passthrough.
  5.  If we manually run the following command from an ssh session:  echo 4 > 
/sys/class/net/ens4f0/device/sriov_numvfs
it will set all of the VFs mac addresses to all zeros.  Then when we assign the 
pci host device to the guest VM through oVirt, it creates unique macs for both 
vnics.  However, when we reboot the Host, it seems to revert back to the oVirt 
assigned macs of 02:00:00:00:00:01.
Do know why this might be happening?  Should we be assigning the VFs to the 
guest VM by adding a network interface with type PCI Passthrough?  Ultimately 
our goal is to enable sriov within oVirt and be able to assign multiple VFs to 
the guest VMs with each getting a unique mac.  We also want to do the vlan 
tagging via an application running on the guest VM (not at the Host level.)
Thank you for any help,
jp

[ovirt-users] Data Path Operations On Any Host

[SOFTWARE (WG)]

Hi,

In relation to the change made to distribute data operations between all the 
hosts in a data center rather than burden the SPM. I am having troubles finding 
information on this and need assistance to prevent this happening on my 
development oVirt 4.2 system. The issue I have is that I have a cluster which 
hosts all the storage volumes using gluster and they have 10G NICs. I also have 
a separate cluster which is virtualisation only and each host only has 3 x 1G 
aggregated NICs. When I perform disk moves between storage domains it often 
uses one of the virtualisation hosts which drastically increases the time taken 
to move the disk. Can I restrict these types of operations to a set of hosts or 
turn it off altogether so that it just uses the SPM like it used to in the 
past. Distributing it is a great feature but unfortunately is no good in my 
current setup.


Regards,

Jeremy

Yes, you’re right. Restarting libvirtd.service solves this situation.

firealld was manually installed/restarted before and then libvirtd.server got 
confused.

Thanks a lot!

No, the date was correct - search the list archives for 'hackathon':

Only that the last mail from Rob was sent a month too late, perhaps some
bug in some calendar software somewhere.
