That question is:
 Add lines for the appliance itself and for this host to /etc/hosts on the
engine VM?
 Note: ensuring that this host could resolve the engine VM hostname is
still up to you

As Didi stated the properly way to use that is with a properly working
DHCP/DNS infrastructure having each host resolving each others and so on.
Then hosted-engine setup will ask you about engine VM mac address and you
have to create a reservation for that on your infrastructure.

For smaller/test deployment where a DHCP server is not present we are
providing also a static IP addressing option for the engine appliance:
you can specify an IP address for your new VM and it will be configured in
the appliance via cloud-init.
Then your host should be able to resolve it and so, if you don't have a
registering DNS,  it's up to you to configure it via /etc/hosts on your
host.

Cause the appliance deployment is fully automated you don't have the time
to do it on the appliance and so we provided a way to inject the host
address into /etc/hosts on the appliance.
It's still up to you to add other hosts there if you want to deploy
additional ones.
So having a properly working DNS and DHCP server is definitively a better
option.

1. Hit your screen prefix combination ( C-a / control + A by default), then
hit Escape .
2. Move up/down with the arrow keys to scrool the output buffer.
3. When you're done, hit Return twice to get back to the end of the scroll
buffer.

Depending from where it stopped it could be that you have to manually
destroy your previous empty appliance instance and cleanup its storage
before being able to retry.

[ovirt-users] Testing self hosted engine in 3.6: hostname not resolved error

[Gianluca Cecchi]

Hello,
playing with an environment where I have a CentOS 7.1 + updates server with
3.6 repos configured.
no DNS resolution in place.
running the command
hosted-engine --deploy

I initially get, during the prompts inside setup, the message if I want to
set hostname for the sh engine and if I want to setup /etc/hosts of
hypervisor and sh engine so that it will add them with clud-init, that
translates in these lines inside log file:


2015-10-21 15:45:29 DEBUG otopi.context context.dumpEnvironment:510 ENV

2015-10-21 15:45:29 DEBUG otopi.context context.dumpEnvironment:510 ENV
OVEHOSTED_VM/cloudinitVMETCHOSTS=bool:'True'

But then I get the error related to failure of sh engine hostname
resolution and installation terminates, with these finale lines in log
file.

and the message of a generated answer file.

Why does it ask and then fails?
Can I re-run using the answer file? In this case do I have to pre-insert sh
engine hostname inside /etc/hosts of hypervisor?

Thanks.

IIRC we only suggest to update /etc/hosts of the engine, not the host.

Generally speaking, you are supposed to take care of all name resolution
yourself. Changing /etc/hosts on the engine vm was added mainly to allow
unattended setup of it.

Note that you also have to make sure the engine can resolve the host, and
that the hosts can resolve each other. See also [1] about that.

What is the supposed command for using answer file?
What should have it put the generated output file? It seems there is
nothing under /etc/ovirt-hosted-engine

[root@ovc71 ovirt-hosted-engine-setup]# ll /etc/ovirt-hosted-engine
total 4
-rw-r--r--. 1 root root 222 Oct 15 10:37 10-appliance.conf

AH ok.. I found it under

So it remains the question regarding syntax for using answer file..

Re: [ovirt-users] MacSpoof with multiple VM's -> bad/slow response on 3.5.3

[Matt .]

Hi Dan,

Yes it vanished from the gui.

The strange thing is I was looking using VdsClient and saw my
loadbalancers where not started with macspoof true, but my Firewalls
were.

In the time between they have been migrated and restarted also in
tests, so I cannot see if it has been running with macspoof true and
it vanished from the gui, but I'm 200% it was in there (GUI).

Now this is double checked etc all working fine again, I wonder if
macspoof can have issues with multiple VHID groups in between the same
hosts on the same vlan.

It's kinda guessing as I cannot show how it was setup, this came up
during some failover test after the machines have been moved to
dedicated hosts some while ago.

So, ask me, shoot me and maybe we can tackle if this could be a bug or so.

Thanks,

Matt

[ovirt-users] schedule a VM backup in ovirt 3.5

[Indunil Jayasooriya]

Hi list,

I want to *schedule a VM backup* in ovirt 3.5. I read below URL.


http://www.ovirt.org/Features/Backup-Restore_API_Integration#Full_VM_Backups

It gives an below example of VM backup


Example for VM Backup

   - Use existing VM Snapshot/Create a vm snapshot (example):

 URL = SERVER:PORT/api/vms/VM_ID/snapshots
 Method = POST
 (with Content-Type:application/xml header)
 Body =
 
 Virtual Machine 1 - Snapshot For Backup
 



But, How can I find the *VM_ID* of the VM that I want to backup?

How can I write this below format?

 URL = SERVER:PORT/api/vms/VM_ID/snapshots

MY Ovirt Engine manager is running on another PC. (let's say
engine.example.com ) i can access it by typing
https://engine.example.com/

is it https://engine.example.com/api/vms/*VM_ID*/snapshots ? I can't
access it in firefox browser?


Should I write a script? is there any Youtube video or doc that makes
me to understand this?

Hope to hear from you.

Hi Kevin,


you should not change auth_unix_rw=sasl. I never used libvirt-snmp but it
is save to create another user like this:

I did that several times on my hosts.

OK. It went successfull fro engine point of view.

One note: I chose spice as protocol for the sh engine and while I was able
to connect to it using root user, I wasn't using a normal user.

Hi Maor,
Thanks for your help.

Please find the logs attached. I cut them a bit, so I hope they contain 
everything you need.

The server was started about 6 months ago.
There are 2 DCs: "default", which is empty and "Tilburg" with 1 cluster and 1 
host.
There are 4 storage domains. 1 ISO (NFS) and 3 "Local on Host".

It's a bit of a too-lite setup for oVirt, but the interface is great.

>I got confused here, you wrote that you can't start a domain in the mail
>subject, but you mentioned that you have tried to run a VM.
>did you try also to reconstruct your DC?

It was morning in Europe. And I was sloppy with terms. Sorry for the confusion.
Domain is supposed to be "Virtual Machine".

I created it fresh, and allocated a thinly provisioned disk on one of the 
"Local on Host" storage domains.

Pressing "Run" or "RunOnce" for the virtual machine consistently results in:
"
VM build-arm-mcu is down with error. Exit message: internal error unsupported 
flags (0x1) in function virLockManagerSanlockNew.
"

Re: [ovirt-users] Issue with kernel 2.6.32-573.3.1.el6.x86_64?

[Michael Kleinpaste]

VMs are on different VLANs and use a central Vyos VM as the firewall and
default gateway.  The only indication I had that the packets were getting
dropped or being sent out of order was by tshark'ing the traffic.  Tons and
tons of resends.

The problem was definitely resolved after I dropped back to the prior
kernel (2.6.32-504.12.2.el6.x86_64).

Re: [ovirt-users] How to change the hosted engine VM RAM size after deploying

[Bond, Darryl]

When I try to change the RAM settings I get the following in a popup box.

Cannot edit virtual machine disk. This VM is not managed by the engine.


After some fiddling it seemed to accept the memory setting even though the 
dialog was showing the error.

Restarting the via hosted-engine -vm-shutdown & --startup, the Vm still had the 
old memory settings even though the engine GUI shows the new setting.

How can I increase the RAM for the VM without re-deploying it?

Please try manually importing the hosted-engine storage domain into the engine 
(it should work automatically but currently it's still non there).
At that point the engine VM should come up into the engine and you should be 
able to edit some parameters including its memory.
When done shutdown the engine VM. The hosted-engine HA agent will bring it up 
for you with the new configuration.

 Hi Friends of oVirt

 This the data required:

 I have a HP Enclosure with a HP SAN.
 I can't change the net settings in the switch because we have VMware
 Virtual Machines in production in the same enclosure.
 The switch is in Trunk Mode and all the traffic are in Tagged VLAN's
 with ID's: 1,50,90,91 and 100.
 I can play with 6 blades.
 I in the first Blade I installed oVirt in hosted engine mode.
 The only S.O is CentOS 7.1

 I used inxi to brig the data for you:

 My First Host is the only host until now (SPM) is the first data domain
 (NFS) and contains the hosted engine machine.
 I installed oVirt with ovirtmgmt in VLAN 1, over the interface eno1,
 without any VLAN Tagged configuration.

 This the data for my first host:

 http://pastebin.com/dfC0XTQM

 This the data for the Engine:

 http://pastebin.com/JdrMSbj0

 This the data for the Virtual Machine created in VLAN 50:

 S.O : CentOS 7.1
 SELinux: Permissive
 IP ADDRESS: 192.168.50.8
 PREFIX: 27
 GATEWAY: 192.168.50.1
 Interface: eth0

 The Virtual Machine hasn´t any VLAN configuration.

 In the 3 S.O,

Hi Michael,
Can you describe your network architecture for this vm (inside the host).
Do you know where are the packets get dropped?

You can backup the engine only.
http://www.ovirt.org/Ovirt-engine-backup
But without the disks, you will not be able to start any VM.

Re: [ovirt-users] stange behavious on virtual machine wilt multiple snapshots

[Roel de Rooy]

I managed to stop the failed messages from being logged within the event log.
I used the clear async task option within vdsClient  to remove the task from 
the host.

After restarting the engine daemon, the error message within the events and the 
finalizing subtasks stopped.
The task itself is still visible as running, so my best guess is that  I have 
to manually remove it from the database, correct?
Already updated the specific tables within the database to unlock the VM and 
the disk inside VM.

Unfortunately I am still puzzled on how to proceed with the error message the 
VM is producing:

"down with error. Exit message: internal error: early end of file from monitor: 
possible problem:

When looking within the vdsm log; before the attempt is made to start the VM, 
the following messages are visible for all images within the specific VM folder:
"Thread-670750::DEBUG::2015-10-21 
10:15:12,775::fileSD::499::Storage.StorageDomain::(activateVolumes) Fixing

Could this be permissions related?

Kind regards,

Onderwerp: [ovirt-users] stange behavious on virtual machine wilt multiple 
snapshots

Hi all,

One of our VM's is behaving strangely.
We are using oVirt Engine 3.5.4.
The host where the VM is located is F20 with virt-preview repository installed.

When trying to start the VM, the following error message is visible:

"down with error. Exit message: internal error: early end of file from monitor: 
possible problem:
2015-10-20T00:06:08.134352Z qemu-system-x86_64: -drive

file: Could not open backing file: Could not open backing file: Could not open 
backing file: Could not open backing file: Could not open backing file: Could

After investigating this issue, we found out that the VM had 25 disk snapshots 
attached.
We tried to remove 2 of them, which succeeded, but due to the time it would 
take to remove them all, we figured it would also be possible to just export 
the vm to the exportdisk and reimport it again.

Unfortunately now the attached screenshot is happening.

Each of the 'finalizing' subtasks corresponds with a 'Failed to export Vm  
to ' message within the event log.

Is there a possibility  to stop this task?

The vdsClient on the host gives the following info about the task:

5c2763ce-21b7-4669-b66d-5f5ea075be4a :
    verb = moveImage
    code = 0
    state = finished
    tag = spm
    result =
    message = 1 jobs completed successfully
    id = 5c2763ce-21b7-4669-b66d-5f5ea075be4a

Re: [ovirt-users] How to change the hosted engine VM RAM size after deploying

Please try manually importing the hosted-engine storage domain into the
engine (it should work automatically but currently it's still non there).
At that point the engine VM should come up into the engine and you should
be able to edit some parameters including its memory.
When done shutdown the engine VM. The hosted-engine HA agent will bring it
up for you with the new configuration.

What do you mean by "vanished"? Does it not show on the UI? When did it
happen? Can you share the domxml of the VMs that you start?

I got confused here, you wrote that you can't start a domain in the mail 
subject, but you mentioned that you have tried to run a VM.
did you try also to reconstruct your DC?

Regarding the VM, can please share the following output from the folder 
/rhev/data-center/124ae76f-8acb-412e-91cc-dff9f6ec665d/7be6092d-fce1-45b5-a383-3ead3cdfe457/images/bb5d12ce-1845-42c8-8a6c-abbb73999f5d/:

1) ls -ls

2) also what is the output of each volume in the folder:
 Please try to execute qemu-img info {Guid of each volume in the image folder}

Thanks,
Maor

Hi Joris,

Please attach the engine, VDSM and sanlock logs (/var/log/sanlock.log).
Which Storage Domains does this setup contains? Can you create a disk?

Thanks,

There have been experiments in such direction, you can find more info here:

[ovirt-users] Failed to start domain due to internal error with sanlock

[Joris Dobbelsteen]

Hi all,

I'm currently using oVirt 3.5.4.2 on Centos 6 (single system, not a cluster 
setup). After running for a long while (months), it has run into an issue where 
it current cannot start a new VM.
An internal error happens due to feature (0x01) from libvirt...SanLock...New.

If there are request for specific log files for analysis, please let me know 
and I will include these.

Does anyone recognize this issue or know a resolution?

Best regards,

- Joris Dobbelsteen
