[ovirt-users] Re: Change host names/IPs

[Davide Ferrari]

It's not urgent, I was planning to do it in the next months so I was
gathering info. Will this feature land in some new oVirt version perhaps?

[ovirt-users] Re: Change host names/IPs

[Davide Ferrari]

Well, actually I want to migrate both DNS hostnames and the subnet (from a
/24 to a /16) to which the ovirtmgr interface is connected.
The second change is the most problematic as you say..in any case what
would be the best procedure, even if it implies downtime?

Yep, I'm with HE. Does anyone know if HE engine can be changed?

Luckily storage is already on another vlan/network

Well I have a mix of physical hosts (excluding oVirt cluster obviously) and
VM that are all on the same network right now, which is the ovirtmgmt
network too, and I don't want to have special routing rules only for VMs.

Thanks for the tips!

Yep, it happens only for the 96GB VM. Other VMs with fewer RAM (16GB for
example) can be created on or migrated to that host flawlessly. I'll try to
play a little with BIOS settings but otherwise I'll have the HW replaced. I
was only trying to rule out possible oVirt SW problems due to that host
being the first I deployed (from CLI) when I installed the cluster.

Thanks!

[ovirt-users] Change host names/IPs

Hello

Is there a clean way and possibly without downtime to change the hostname
and IP addresses of all the hosts in a running oVirt cluster?

Re: [ovirt-users] Host in kdumping state

[Davide Ferrari]

Sorry for not following-up...well as strange as it sounds, after replacing
the faulty HW while keeping the same old disks (basically putting the disks
in a new identical server) the kdumping error disappeared and the host is
back working as usual.
Maybe "kdumping" is displayed after a kernel panic reboot?

Thanks

[ovirt-users] Host in kdumping state

[Davide Ferrari]

Hello

I've got a faulty host that keeps rebooting itself from time to time 
(due to HW issues), that is/was part of the 3 hosts group hosting the 
HostedEngine, and now it always appears as "Kdumping" in the web 
administration panel.


All my hosts are oVirt 4.1 on Centos 7.3 with glusterfs 3.7 but this one 
that was updated by mistake to Centos 7.4 with glusterfs 3.8.


Is this due to the different OS/gluster version? How can I "reset" it? I 
want to remove it permanently and assign the HostedEngine to another host?


Moreover, the main glusterfs volume, the one which holds the HE image, 
has some bricks on this failing machine (vm03):


#  gluster volume status data_ssd
Status of volume: data_ssd
Gluster process TCP Port RDMA Port  Online  Pid

What's the best way to replace them? Is this guide still useful?

The oVirt access log indeed shows that three disks are added to the

explicitly add a boot disk? Ohad, Ivan, any idea?




I've explicitly added the template id to the hammer command line and 
still adds 3 disks but at least now two of them respect the size I'm 
passing through Hammer. But it still sets a random disk as the bootable 
one and I cannot find a way to force to use the disk already present in 
the oVirt template as the bootable one
Is there a way in oVirt to log the JSONs passed in the various POST 
requests?




More over, looking at 
/ovirt-engine/api/vms/47f5035a-696c-4578-ace9-b23d865c6aa7/disks it 
throws a 404, the endpoint seems to be 
/ovirt-engine/api/vms/47f5035a-696c-4578-ace9-b23d865c6aa7/diskattachments 
while 
/ovirt-engine/api/vms/47f5035a-696c-4578-ace9-b23d865c6aa7/disks 
seems to work only with API v3. Maybe I should change the base URL 
for the ovirt's API in foreman config, shouldn't I?




I think you don't need to change anything there. Foreman uses 
'rbovirt', and 'rbovirt' explicitly requests version 3 of the API 
using the 'Version: 3' header. 


Well, I've added it anyway and it didn't break anything :)

Ah, I see, in your command you are listing Gluster volumes, not

Oh, got it. Thanks for the tip!

Anyway, I've replaced the storage domain UUID with the one that works 
with the REST API and something improved: now I don't get the 404 
from ovirt and the machine is not deleted BUT:  I've added 2 disks 
(20GB and 30GB) plus the base template 8Gb disk, and I get a VM with 
four (4) 8GB disks, and the bootable one is a random disk


I've attached the engine.log with the (I hope) relevant messages



Are you adding those disks and template using the Foreman CLI? Can you 
share the commands that you are using?




Yes, I'm using Hammer CLI

hammer host create --architecture-id=1 --domain billy.preprod 
--operatingsystem-id=7 --hostgroup-title Billy/Preprod --name foobar03 
--partition-table-id=192 --provision-method image --root-password

Also, can you share again the relevant part of the 
/var/log/ovirt-engine/ssl_access_log file? There we can see what 
requests are actually sent to the oVirt engine.

Looks like the oVirt engine is rejecting the request to add the disk

Would be nice if you can check the /var/log/httpd/ssl_access_log in 
the oVirt engine machine. There should be a line there with the 404 
HTTP status, something like this:


  POST /ovirt-engine/api/vms//disks 404

What is the exact content of that line? Is the VM id the one that 
appears in the above message.


Bingo, there's definitely a 404 error log at the same hour:

192.168.10.158 - - [25/Jul/2017:08:28:02 +] "POST

HTTP/1.1" 404 169


But the ID is different



Also, can you check what are the identifiers of the relevant data 
center and storage domains?




DC and storage UUID "should" be correct, I've copied them from the oVirt 
CLI output into my hammer command
These are the storage IDs for the datacenter where I'm trying to create 
the VM in:


[oVirt shell (connected)]# list glustervolumes --cluster-identifier 
0002-0002-0002-0002-0345


id : 23f8f1ae-a3ac-47bf-8223-5b5f7c29e508

and this is the command line I'm using

hammer host create --architecture-id=1 --domain billy.preprod 
--operatingsystem-id=7 --hostgroup-title Billy/Preprod --name foo01 
--partition-table-id=192 --provision-method image --root-password

Nope, no log with the same timestamp in server.log :/

Not sure if you're facing the same issue, but maybe worth looking into...

Well, actually I can create a VM both from Foreman UI and Hammer CLI, 
the problem arises when I'm trying to add more disks to that VM

Hello

I've attached logs from:

- hammer cli (debug) with the command line I've used

- foreman logs

- ovirt engine logs (server.log)


Basically I was trying to create a VM from an ovirt template linked to a 
Foreman image (CentOS_73) which consists of a single disk with the OS, 
and attach via Hammer 2 more disks. In this case I get a 404 Resource 
Not Found from Foreman and what I see in the ovirt logs is that the VM 
is created and then immediately deleted via API



Thanks!

Also, by default, RHV 4.1 will use v4 of the api, so you have to use a 
URL in Foreman that uses v3 (as Foreman doesn't support v4 yet).


I assume that's not your issue, otherwise you would have encountered 
more basic issues.


Also, can you please share your logs from both environments?

Ohad/Ivan, any clue?

Re: [ovirt-users] Detach disk from one VM, attach to another VM

how do you remove the disk from the VM's configuration? From the disk 
tab under the VM?



On 11/07/17 20:51, Victor José Acosta Domínguez wrote:

Hello

Yes it is possible, you must remove from first VM's configuration (be 
careful, do not delete your virtual disk)


After that you can attach ad that disk to another VM

Process should be:
- Detach disk from VM1
- Delete disk from VM1's configuration
- Attach disk to VM2

[ovirt-users] Detach disk from one VM, attach to another VM

[Davide Ferrari]

Hello

I'm using oVirt 4.1.3 and I was wondering if it's possible to detach a 
disk created specifically for a VM from that VM and attach it to another 
VM.


Reading this

https://www.ovirt.org/documentation/admin-guide/chap-Virtual_Machine_Disks/

it seems that's only possible with floating virtual disks, but I have a 
disk that was created for a specific VM.

[ovirt-users] Upgrade guide for oVirt 4.1.x?

Hello

following the links from the official release notes, I always end up to
this page

Is this still valid for 4.0 -> 4.1 upgrades?

[ovirt-users] Details about why a live migration failed

[Davide Ferrari]

Helo

I have a VM on a host that seems it cannot be live-migrated away. I'm
trying to migrate it to another (superior) cluster but please consider:
- VM isn't receiving too much tarffic and is not doing much at all
- I've already successfully live migrated other VMs from this host to the
same other cluster

looking through engine.log I cannot see anything interesting a aprt from
the generic ( I grepped for the job ID)

error in the gluster volume which I created via CLI manually, I forgot to
set the vdsm unix user UID and GID permissions to it. After doing that, I
could import the new gluster volume as a data domain in the new cluster and
then enable Gluster management in the cluster and now everything works as
expected!

About this: why?
I mean, from the new cluster I can spawn a VM based on an image stored in
the other cluster domain and it works.  What's the problem?
Anyway I created a new data domain for that cluster

I get this error when I click "

Restart Glusterd service" in the Genral tab of a the sole host in a new
cluster. I've enabled "Manage Gluster" in the cluster options and already
created a new gluster volume (via CLI) with bricks only in the hosts that
are part of this new cluster.

So, how should I create the new, dedicated gluster volume? Within oVirt or
on the command line as I created the first data volume when I installed
oVirt from scratch? I guess the former should work, right?
But then, can I do live migrations from the lower CPU cluster to the newer
one? I guess it's possible according to this:

Thanks for your time

I may add that as of now I've just added the bricks and nothing more, no

bricks)

[ovirt-users] Expand an ovirt+glusterfs cluster

[Davide Ferrari]

Hello

I have a 4 node oVirt 4.0 cluster running on top of glusterfs volumes,
managed by the oVirt cluster (option ticked in the cluster properties)

Now, I'm adding several new nodes to this cluster with a better CPU
(Broadwell vs Haswell) but now comes the "bad" part. Out of enthusiasm I've
already added storage from these new servers to the data volume already
present and used by the current cluster. In fact now ovirt has detected new
hosts and it's asking me if I want to add these host to the cluster.

But there are two problems:
1) I want to create a new, Broadwell cluster
2) I'm using a separate VLAN+domain name for gluster, and oVirt is
proposing me to use the gluster (storage) domain names as the new hosts
identifier.

What are the right steps/actions to take now? It's a running production
system.

Thanks in advance

[ovirt-users] oVirt 4 and 10GbE NICs

[Davide Ferrari]

Hello

the oVirt hosts in my cluster have all 10GbE interfaces (bonded 2 by 2),
and I was wondering if a single Linux VM with a virtio interface can reach
for example 8Gbps.

I'm asking because I'm seeing a 100% network usage in some VMs in ovirt VM
dashboard but the real traffic in that VM is between 1-2Gbps.

Thanks

[ovirt-users] Upgrade cluster + adding nodes

[Davide Ferrari]

Hello everyone

currently I've a 4-nodes oVirt 4.0.4 cluster running on CentOS 7.2.
Given that we have now oVirt 4.0.6 and CentOS 7.3, what's the best update
path? I was reading threads about qemu-kvm-ev 2.6 when CentOS 7.3 was
released but I was wondering if with 4.0.6 release something has changed.
Moreover, I'd like to add 4 more nodes in the near future, I guess I should
have all the same version and thus I must fully upgrade the original 4
nodes (both OS + oVirt) before adding new, fully up-to-date nodes, right?

Thanks!

Re: [ovirt-users] Could not associate brick

Yes, the brick on vm04.storage.billy correctly resolves in the
hosted-engine VM to 10.30.0.4, and that IP is set in the corresponding
hosts' bond1 (linked to the "gluster" network interface I created in
"Networks")

I'm seeing several ot these warnings:

How can I fix this?

just for the record, after I have that server replaced (only

Well I have a mix of physical hosts (excluding oVirt cluster obviously) and
VM that are all on the same network right now, which is the ovirtmgmt
network too, and I don't want to have special routing rules only for VMs.

Thanks for the tips!

Re: [ovirt-users] Change host names/IPs

Well, actually I want to migrate both DNS hostnames and the subnet (from a
/24 to a /16) to which the ovirtmgr interface is connected.
The second change is the most problematic as you say..in any case what
would be the best procedure, even if it implies downtime?

Yep, it happens only for the 96GB VM. Other VMs with fewer RAM (16GB for
example) can be created on or migrated to that host flawlessly. I'll try to
play a little with BIOS settings but otherwise I'll have the HW replaced. I
was only trying to rule out possible oVirt SW problems due to that host

Re: [ovirt-users] Ovirt/Gluster replica 3 distributed-replicated problem

[Davide Ferrari]

It's strange, I've tried to trigger the error again by putting vm04 in
maintenence and stopping the gluster service (from ovirt gui) and now the
VM starts correctly. Maybe the arbiter indeed blamed the brick that was
still up before, but how's that possible?
The only (maybe big) difference with the previous, erroneous situation, is
that before I did maintenence (+ reboot) of 3 of my 4 hosts, maybe I should
have left more time between one reboot and another?

Re: [ovirt-users] VM pauses/hangs after migration

[Davide Ferrari]

Ok, what I said is not true :( I didn't try to migrate again to the same
host that gave the initial problem, and the problem is still there. The
destination host has no HW problem (at least nothing that the system
reports, maybe I should try with an extensive memtest86) and the source
problem now has no memory issues neither. So, my question is now: how can I
debug this problem? The only difference that this host (vmhost01) has is
that it was the first host installed in my self-hosted engine installation.
But I have already reinstalled it from GUI and menawhile I've upgraded to
4.0.4 from 4.0.3.

Re: [ovirt-users] VM pauses/hangs after migration

[Davide Ferrari]

Hello

Today I've the faulty DIMMs replaced, started the same VM again and did the
same migration and this time worked, so it was 100% due to that.

The problem that make me wonder a bit is: if it's the source host with
memory problem the one which blocks the correct migration, a faulty DIMM
will force you to stop the VMs running on that host, because you cannot
simply migrate them away to do the maintenence tasks...

[ovirt-users] Ovirt/Gluster replica 3 distributed-replicated problem

[Davide Ferrari]

Hello

maybe this is more glustefs then ovirt related but since OVirt integrates
Gluster management and I'm experiencing the problem in an ovirt cluster,
I'm writing here.

The problem is simple: I have a data domain mappend on a replica 3 arbiter1
Gluster volume with 6 bricks, like this:

Status of volume: data_ssd
Gluster process TCP Port  RDMA Port  Online  Pid
--
Brick vm01.storage.billy:/gluster/ssd/data/

Self-heal Daemon on vm03.storage.billy  N/A   N/AY
23205
Self-heal Daemon on vm04.storage.billy  N/A   N/AY
8246


Now, I've put in maintenance the vm04 host, from ovirt, ticking the "Stop
gluster" checkbox, and Ovirt didn't complain about anything. But when I
tried to run a new VM it complained about "storage I/O problem", while the
storage data status was always UP.

Looking in the gluster logs I can see this:

Now, how is it possible to have a split brain if I stopped just ONE server
which had just ONE of six bricks, and it was cleanly shut down with
maintenance mode from ovirt?

I created the volume originally this way:
# gluster volume create data_ssd replica 3 arbiter 1
vm01.storage.billy:/gluster/ssd/data/brick
vm02.storage.billy:/gluster/ssd/data/brick
vm03.storage.billy:/gluster/ssd/data/arbiter_brick

If you're running a guest on an Intel machine without unrestricted mode
support, the failure can be most likely due to the guest entering an invalid
state for Intel VT. For example, the guest maybe running in big real mode
which is not supported on less recent Intel processors.

Searching for errors like this I found some bug report about kernel issues
but I don't think it's the case, other VMs spawned from the same image
migrate without any issue. I have toi say that the original host running
the VM has some RAM problem (ECC multibit fault in one DIMM). Maybe that's
the problem?
How can I properly read this error log?

Thanks

Following this

https://access.redhat.com/discussions/688043

even if it's 4 years old, I've resatrted ovirt-engine on HE vm and now the
status is OK again

[ovirt-users] HE vm stuck in migration state

[Davide Ferrari]

It's running on my vm01 host and when I tried to manually migrate it on
another host (vm03) which had a "ghost" VM count (it's a fresh cluster
install with just the HE running in it), the migration started, the VMs
count in vm03 went to 0 but then the HE machine got stuck in migration.

Actually it's still perfectly running on vm01, it seems that it's just a
database state. Is there a way to force a refresh?

Re: [ovirt-users] 4-node oVirt with replica-3 gluster

[Davide Ferrari]

Reading the glusterfs docs

https://gluster.readthedocs.io/en/latest/Administrator%20Guide/arbiter-volumes-and-quorum/

"In a replica 3 volume, client-quorum is enabled by default and set to
'auto'. This means 2 bricks need to be up for the writes to succeed. Here
is how this configuration prevents files from ending up in split-brain:"

So this means that if one of the machines with the 2 bricks (arbiter &
normal) fails, the otherbrick will be set RO, or am I missing something?
I mean, this config will be better in case of a network loss, and thus a
split brain, but it's far worse in case of a machine failing or being
rebooted for maintenance.

Ok, cool! And this won't pose any problem if Node2 or Node4 fail?

The syntax shuld be this:

gluster volume create data replica 3 arbiter 1 node1:/brick node2:/brick
node2:/arb_brick node3:/brick node4:/brick node4:/arb_brick

is not a problem having more than a brick on the same host for the volume

Mmmmh this is ringing an alarm bell then. So, it's basically impossible (or
at least not supported) a 4 hosts configuration with all the 4 hosts having
a data domain in a replica 2 fashion? Is it only replica 3 arbiter 1 the
supported HA configuration? So if I want to expand storage (a part from
adding disks to the same machines) I must add machines 3 by 3 ?

Currently I have 4 machines with 4 disks each in a RAID-10 configuration,
exposed as one brick. Which is the best HA solution in this scenario then?

[ovirt-users] cloud-init and user password

[Davide Ferrari]

Hello

I'm using a Centos7 cloud image from built-in ovirt-image-repository and I
have some trouble setting an initial password for a given user with
cloud-init.

Basically, it doesn't set any password. Other things work: user is created,
ssh key is set (both for the user and root) but no password. This is a
problem for me because I want to automatically provision the image with
Foreman but the ovirt integration works only with password.

The cloud-init logs in the VMs doesn't tell anything about password being
or not set.
What's the password format accepted in the GUI? plain text? or salted hash
like plain cloud-init config?

Thanks

Re: [ovirt-users] 4-node oVirt with replica-3 gluster

[Davide Ferrari]

I'm struggling with the same problem (I say struggling because I'm still
having stability issues for what i consider a stable cluster) but you can:
- create a replica 3 engine gluster volume
- create replica 2 data, iso and export volumes

Deploy the hosted-engine on the first VM (with the engine volume) froom the
CLI, then log in Ovirt admin, enable gluster support, install *and deploy*
from the GUI host2 and host3 (where the engine bricks are) and then install
host4 without deploying. This should get you the 4 hosts online, but the
engine will run only on the first 3

Re: [ovirt-users] Can't add logical network

[Davide Ferrari]

By the way, what are the exact steps to add a new network in oVirt?
Because I was following this guide

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

that basically explains how to create manually a standard bond+vlan+bridge,
that I already did on my ovirt hosts, but I can't manage to get the network
working in the VMs. Ovirt always complains about that the network is not
available on that host.
I created a network named "br20" in my case.
My ifcfg-* files:

[root@vm04 network-scripts]# cat ifcfg-bond0.20
DEVICE=bond0.20
VLAN=yes
BOOTPROTO=none
NM_CONTROLLED=no
BRIDGE=br20
MTU=1500
[root@vm04 network-scripts]# cat ifcfg-br20
TYPE=Bridge
NM_CONTROLLED="no"
BOOTPROTO="none"
DEVICE="br20"
IPADDR=192.168.9.228
NETMASK=255.255.255.0
ONBOOT="yes"
DEFROUTE=no

What am I missing?

Re: [ovirt-users] Import Glance images in oVirt 4.0

[Davide Ferrari]

Ouch! Didn't see it, my bad :/
I found more easily the new upload image function than the old feature

Thanks a lot!

Mmmh, how can I check this? And how can I cahnge the id from the engine?
IDs are not even shown in the GUI for example

[ovirt-users] Import Glance images in oVirt 4.0

[Davide Ferrari]

Hello

all the guides/helps/howto I can find about importing OpenStack Glance's
iamges into ovirt relies on 3.x version and on the "ovirt-image-repository"
present as a storage domain. But in 4.0 I can only see it as an expternal
provider and there's no way to add it a storage domain (I can only add
"Data" domains). So, how can I import existing images into my oVirt 4.0
installation?

Thanks

Re: [ovirt-users] Replace one engine host

[Davide Ferrari]

Oh, thanks! You put me on the right way! Now it works:
Steps that I did:
- reinstall + deploy vm03
- manually set from maintenance to none on vm03
- reinstall + undeploy vm04 (I left it deployed again last time, trying to
remove it)

Then I found the problem: vm03 hosted-engine conf
(/etc/ovirt-hosted-engine/hosted-engine.conf) had host_id set to 4 which
conflicted with vm04 host_id. So I changed it to 2 (the only one free),
restarted ovirt-ha-agent (and broker just to be sure) and it worked! Now
from vm-status I see vm01,02 and 03 with 3400 as priority and I can migrate
the HE vm to any of them!

Thanks a lot for your kind help, Roy!

Re: [ovirt-users] Replace one engine host

[Davide Ferrari]

Hello Roy, I forgot to mention that I already reinstalled (several times)
vm03 from the gui with the deploy option checked, but there's no way it
appears there. For the record vm04 was the first host deployed (from cli)
after the initial vm01 installation, then vm02 and then 03.

[ovirt-users] Replace one engine host

[Davide Ferrari]

Hello

Still playing a bit with oVirt, my cluster is ovirt+gluster with a replica
3 glusterfs for the engine (on vm01, vm02 and vm03) and 4 hosts for the
data glusterfs and running virtual machines (vm01, vm02, vm03 and vm04).
Now, by mistake, I deployed hosted-engine on vm04 but I don't want to have
the engine on a machine without local data + it's not working correctly
(weight 0 and marked as in maintenance). Now, I've already tried to
reinstall it from the the GUI marking the "Undeploy" check, reinstall vm03
marking the "deploy" check but nothing seems to work. Here it is the
hosted-engine --vm-status output from vm04. What can I do to deploy
correctly the hosted engine on vm03?

Ok, HE moved to host1...now, sorry for being so silly but, how do I remove
a host from ovirt-engine GUI? "Remove" (just as reinstall) is greyed out too

Re: [ovirt-users] Add more hosts

[Davide Ferrari]

Trying to set the maintenance gives me:

[root@vm01 ~]# hosted-engine --set-maintenance --mode=global
/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/lib/storage_backends.py:15:
DeprecationWarning: vdscli uses xmlrpc. since ovirt 3.6 xmlrpc is
deprecated, please use vdsm.jsonrpcvdscli
  import vdsm.vdscli


it's not vey clear if it worked and it's just a warning or since it's
deprecated it didn't work at all

All from the CLI. Right now in the GUI I have the "Reinstall" button greyed

[ovirt-users] Add more hosts

[Davide Ferrari]

Hello again

as I said I'm a beginner with OVirt and I was playing with a
proof-of-concept cluster with OVirt 4.0 + GlusterFS 3.8, following this
guide

http://www.ovirt.org/blog/2016/03/up-and-running-with-ovirt-3-6/

(it works smoothly with 4.0 too)
I've created the cluster and the engine is running as an higly available VM
in the cluster itself with hosted-engine --deploy but now I want to add a
fourth machine to the cluster but I get this error:

 Cannot automatically add the host to cluster Default: Cannot add Host.
There is no available server in the cluster to probe the new server.

both if I try to add an host from Ovirt AAdmin GUI or if I try to run
"hosted-engine --deploy" on the new machine. Is it possible to have this
cluster conf (with the engine running as a VM) with 4 or more machines?
What thing should I have to do?

Thanks in advance

Re: [ovirt-users] Hosted engine deploy: problem with the rDNS of another iface

[Davide Ferrari]

And indeed it was the problem. So, you must have working reverse dns lookup
to complete the setup succesfully.

Thanks for the help!

Re: [ovirt-users] Hosted engine deploy: problem with the rDNS of another iface

[Davide Ferrari]

Well but the fact is that it DOESN'T resolve on bond1, there's no DNS entry
anywhere resolving to that IP for vm01.mydomain.tld
That's the strange thing, I don't really get from where python's
socket.gethostbyaddr() gets those 2 IP addresses :/

The only thing that it comes to my mind is that the domain I'm using
(mydomain.tld) doesn't have PTRs properly set (and I cannot fix it without
migrating the domain...yeah it's ugly as hell what I have here, I know :(
), maybe it's a corner case that should be handled more specifically?

I'll try to add entries for vm01.mydomain.tld in /etc/hosts and see if it
fixes the problem

Re: [ovirt-users] Hosted engine deploy: problem with the rDNS of another iface

[Davide Ferrari]

But bond0/192.168.10.225 is the only interface I have (right now) to
connect to the machine. So, I should create another interface, dedicated to
management? Right now I'm using bond0 as the source iface for the mgm
bridge.

Ciao Simone!

Absolutely, here it is (please not that I've obfuscated domain names but
they are consistent with what I wrote before, the hostnames are exactly the
same I have in my env). If you need the original log, tell me but I will
mail it to you privately.

[ovirt-users] Hosted engine deploy: problem with the rDNS of another iface

[Davide Ferrari]

Hello

I've got the same exact problem as in this thread:

http://lists.ovirt.org/pipermail/users/2016-July/04.html

(sorry for not answering there but I've just subscribed). The error (for
the record) is:

Failed to execute stage 'Setup validation': hostname 'vm01.mydomain.tld'
doesn't uniquely match the interface 'bond0' selected for the management
bridge; it matches also interface with IP set(['10.30.0.1']). Please make
sure that the hostname got from the interface for the management network
resolves only there.

10.30.0.1 is set on bond1 and is used for the glusterfs network. The python
output is:

python -c 'import socket; print(socket.gethostbyaddr("10.30.0.1"));'
('glu-ovirt01.storage', [], ['10.30.0.1'])

which obviously is completely different from vm01.mydomain.tld.
So, I don't really get this error. I've used glu-ovirt01.storage:/engine as
the glusterfs entry point for storing the engine image, that's all.

Any idea on how to fix the error?

TIA
