[ovirt-users] Hosted-engine --deploy FQDN questions

[Mark Steckel]

Folks,

I'm an OVirt newbie having troubles setting up my first Hosted Engine and am 
stumbling. In this case I think it may be because of the following two set-up 
questions.

  Enter the name which will be used to identify this host inside the 
Administrator Portal [hosted_engine_1]:
  Please provide the FQDN for the engine you would like to use.
  This needs to match the FQDN that you will use for the engine 
installation within the VM.
  Note: This will be the FQDN of the VM you are now going to create,
  it should not point to the base host or to any other existing machine.
  Engine FQDN:  []: 

My read of this is that the first question is asking for the name of the host, 
while the second question is asking for the name (FQDN) of the guest vm which 
will be the hosted-engine. Is this correct?

I'm also presuming that a) the first question should be the hostname of the 
host, and b) that both the host and guest hostnames should resolve to IP 
addresses.

Thanks
Mark

Hi Devin,

That's good to hear!

On the ovn-northd node, you need TCP ports 6641 and 6642 open (as mentioned in
Marcin's blog), on the ovn-controller nodes you need to allow packets with
destination UDP port 6081 (Geneve tunnels).

It appears that firewalld was my issue, can you just confirm with me what

 Hi Sandro,
 just tried to install self hosted engine in a nested environment (host
 is free ESXi 6.0 where I also have a working nested oVirt cluster of 3 HCI
 gluster hosts).

 The host is CentOS 7.2 updated with CR repo enabled (so it should be an
 upcoming CentOS 7.3).

Look here:

Still under testing: if something goes wrong you could just reinstall vdsm,
libvirt and ovirt-hosted-engine-setup rpms to get the missing files.

Based on asking around about the "dropping duplicate flow:", it's a
known issue that is harmless (other than the noise). I'll try
to find out if someone has a fix in the works.

It seems your node1 has no port bindings... is that expected?

>From the counters, it looks like node2 and node3 have attempted
to send packets on the geneve tunnels, but neither has received
anything.

Could you verify that node2 and node3 have connectivity on the
IPs used for the tunnels, e.g. by trying to ping 172.10.10.75
and 172.10.10.73 from node2?

If that works, the issue might be iptables rules dropping
geneve packets, the simplest way around that would be to
"systemctl stop firewalld" if that's running (ok for a lab
environment anyway).

Re: [ovirt-users] HE working fine, but still strange messages in /var/log/messages

[Yanir Quinn]

Hi Juan,

You probably see these repeating messages since ovirt-ha-agent is opening
and closing multiple connections.

see BZ:

https://bugzilla.redhat.com/show_bug.cgi?id=1349829

This is probably harmless in the overall picture.

Hi Sandro,
just tried to install self hosted engine in a nested environment (host is
free ESXi 6.0 where I also have a working nested oVirt cluster of 3 HCI
gluster hosts).

The host is CentOS 7.2 updated with CR repo enabled (so it should be an
upcoming CentOS 7.3).

I used the provided appliance in
ovirt-engine-appliance-4.1-20161202.1.el7.centos.noarch

the deploy command arrived at this point and then failed

The logs you attached did not include relevant time intervals.
Are you sure you do not have logs that contain the snippet
you included in-line?

Anyway, you can always try again, and if it still fails, attach the
new logs.

[ovirt-users] HE working fine, but still strange messages in /var/log/messages

[Juan Pablo]

Hi,
first of all, thanks to all the community!
I have Hosted Engine working with no apparent issues I just have the
followiing filling my log messages
:
ovirt-ha-broker:
INFO:ovirt_hosted_engine_ha.broker.listener.ConnectionHandler:Connection
closed
ovirt-ha-broker:

storage domain
ovirt-ha-agent:
INFO:ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine:Preparing

how can I fix this?
I deployed the HE with cockpit, then deployed the next hosts with hosted
engine via UI.

Hi Devin,

OK, some small progress then. I think the best next step would be to look
at the current state of your system. Could you send the output of the
following commands?

On the nodes running ovn-controller:

   ps -fwwC ovn-controller
   ovs-vsctl show
   ovs-dpctl show -s
   ovs-ofctl -O OpenFlow13 dump-flows br-int

On the node running ovn-northd:

   ovn-sbctl show
   ovn-sbctl dump-flows

Thanks,

   Lance

Re: [ovirt-users] feedback and questions about SR-IOV feature

I didn't said it is the right design, i guess that i can get nothing from
such bond and you are right, but,
This is was long discussed a year ago(maybe more) with network DEV when we
planed this feature and it was decided to allow to create bond from VFs.

Thanks,

 As far as I know, it's not possible to do that. The reason is that the
 bond normally creates new (logical) interface, what you are doing is
 assigning "part" of the bond directly to a VM and the driver within VM
 isn't aware of the bond.

 This is what I supposed, UI should prevent us to create VFfrom when nic

 This could be explained by previous statement: bonding PFs at
 hypervisor level and then assigning VFs to a VM can most likely cause
 undefined behavior.

 The issue is the same when the PF is not attached to a bond, so in an

 At hypervisor level? I believe it doesn't make sense.

 I wonder this because UI allows to do it. The same as above, user

 The use case for SR-IOV is maximum performance at the cost of
 convenience while still (somewhat) allowing you to scale.

We are allowing to create bond from them and allowing to attach logical

When creating bond from 2 VFs you should see the pencil icon, because you
want to able to edit the bond.
Vf is an interface and you can use it just as you use regular interface on
the host.

* When you create bond from 2 VFs, this VFs are no longer free and you
can't use them to run VM

There is no problem about it, this is exactly how it was designed ) , you
have to remember that as long as the VFs are not used by VM, they can be
used as regular NICs and you can do with them everything you want.


That doesn't mean we have the right design: there is no problem in
bonding 2 VFs belonging to 2 different PFs; but every sane software
warns you if you try to bond 2 VFs from the same PF together (what do
you get by such bond?) -- this applies to both host and guest.

If you require bond between 2 PFs, you can assign 2 VFs each from
different PF to a VM and bond them within the guest.

Comparing to a large number of restrictions (migration and others), my

opinion is that this feature seems to be very difficult to use in
production...



The use case for SR-IOV is maximum performance at the cost of
convenience while still (somewhat) allowing you to scale.

This snippet is not enough, and the attached logs are too new. Can you
check/share
more of the relevant log? Thanks.

Re: [ovirt-users] web-ui issues

[Maton, Brett]

Ok thanks.

  I've restarted the ui a few times today, still nothing ( at all ) in
ui.log

  The errors do look like 'iffy' queries, no errors in PostgreSQL logs
though.

Interesting, those aren't actually UI failures, those appear to be failures 
from backend requests. As in, get me some data, and the query fails for some 
reason, there should be something in the engine log. Let me dig up the ones 
you posted again and take a closer look.

Re: [ovirt-users] OVA Import - Failed to convert VM

[Shahar Havivi]

Thanks Nate,
The Engine log is correct but the vdsm one is without the error, it maybe
the wrong host, the log that we expected is the one you named CTI04.
If you try to import again please make sure you select the right host in
the import dialog.

 Shahar.

Re: [ovirt-users] feedback and questions about SR-IOV feature

Hello,

My new 10G NICS support now SR-IOV, and I've played with this new 
feature as passthrough device, so as to reduce my host CPU 
consumption.


At the origin, I set up a bond on both 10G PF nics.

After many configurations, the only way I manage to use a VF into a 
VM, is to get out of the bond one nic.


So does it mean that it is impossible to run a VM with VF with PF 
attached to a bond?


As far as I know, it's not possible to do that. The reason is that the
bond normally creates new (logical) interface, what you are doing is
assigning "part" of the bond directly to a VM and the driver within VM
isn't aware of the bond.

Moreover, something strange happens : during the boot of the VM, the 
passthrough device gets an dhcp IP on the native vlan of the bond, and 
once finally up, the real vlan used by this device is on the different 
predifined vlan. It implies to me to reconfigure the network to ping 
something on the wanted vlan. Really crazy.


This could be explained by previous statement: bonding PFs at
hypervisor level and then assigning VFs to a VM can most likely cause
undefined behavior.

Other question is : In which case can it be useful to be able to bond 
2 VF? UI let us to do so, but it is impossible to add any bridge on 
that virtual bond.


At hypervisor level? I believe it doesn't make sense.

If you require bond between 2 PFs, you can assign 2 VFs each from
different PF to a VM and bond them within the guest.

Comparing to a large number of restrictions (migration and others), my 
opinion is that this feature seems to be very difficult to use in 
production...


The use case for SR-IOV is maximum performance at the cost of
convenience while still (somewhat) allowing you to scale.

Other question is : In which case can it be useful to be able to bond 2 
VF? UI let us to do so, but it is impossible to add any bridge on that 
virtual bond.


Comparing to a large number of restrictions (migration and others), my 
opinion is that this feature seems to be very difficult to use in 
production...

Shouldn't we ignore local devices? See [1] for example configuration.

Do you need lvmetad? We think of disabling it.
Y.

[ovirt-users] API req to update power mgmt options

[Emil Flink]

Hi,

Can someone please provide an example request to edit the power management
options of a host?

Ie. the options contained in
host['power_management']['agents']['agent'][0]['options']['option'] and
host['power_management']['options']['option']

Currently I have:

"option": [
  {
"name": "power_wait",
"value": "4"
  },
  {
"name": "lanplus",
"value": ""
  }
]

I need to change the value of "lanplus" from nothing to 1 or "on".

I have tried replacing the entire host['power_management']['options'] set
and the host['power_management']['agents'] set with PUT requests to the API
endpoint for the host, with no change or errors - I just get a 200 OK
response with the details of the host as if I had just done a GET request.


Br.

This patch does not affect the issue that we have with duplicate multipath
entries created during vdsm start.
However, looks like the latest version of lvm2 disables lvmetad when
duplicate PVs are found and pvs command no longer hangs as originally
reported in https://bugzilla.redhat.com/show_bug.cgi?id=1303940  when
tested on RHEL 7.3

Not sure if we should be worried about this warnings or not.

Re: [ovirt-users] hostdev passthrough

If you're not using SRIOV then what do you need passthrough for? If it's
for something like connecting a port that is connected to a mirror port on

for security onion and other systems that need a mirror port to get data


The benefits of passthrough are

a) performance,
b) avoiding host stack (e.g. nic could only have guest OS drivers).

If your host is capable of passthrough[1], you can navigate to the VM
tab -> host devices subtab and assign the nic there.

[1] meaning VT-d (or AMD-vi) properly works
