VM import using wrong/slower interface. help/question.
by Jacob Green
Currently I have a host that has multiple network connections. 1
bonded 20Gigabit connect and a couple of 1 gig Ethernet connections.
Then my export storage domain is on a storage device on a vlan we can
call vlan B.
Today I was exporting a VM from one environment to another, and after I
reattached the export domain and started importing I noticed an even
message for one of my hosts, it looked like the following.
"Host A has network interface which exceeded the defined threshhold
[95%] (eno3: transmit rate [8%], receive rate [98%])" So when I take a
look at that hosts interfaces in the OVIRTENGINE gui I can confirm that
it is exceeding 900Mbits on that interface.
The problem/question is this.
I have the migration network set as well as the ovirtmgmt network on the
20Gigabit interface. The only network profile attached to ENO 3 is
VLAN-B and only VM traffic on that profile. So why is it using that eno3
interface instead of the ovirtmgmt interface on the 20Gigabit interface
to import the VM?
So I do have at least one theory, the storage solution is also on VLAN B
the same VLAN that eno3 rides on, but I am of the understanding that
Ovirt should be instructing the host to use the migration network, which
in my case is also my ovirtmgmt network on the 20Gigabit interface. It
matters because my storage is also on a 20Gigabit bond and these imports
would be a lot faster if it was using the correct network to the host to
import the VM.
I hope my question is clear enough, I would provide screenshots but the
ovirt-users mailing lists scrubs those.
Basically can I instruct or force ovirt to import VMs over my 20Gigabit
interface instead of the slower 1Gig interface that is hooked up.
Thank you.

corrupted hosted engine
by Jarosław Prokopowski
Hi,
It looks like after host restart my hosted engine VM is not accessible any
more.
The storage is glusterfs. The gluster volume is healthy.
The VM status is:
{"reason": "failed liveliness check", "health": "bad", "vm": "up",
"detail": "Up"}
hosted-engine --console
The engine VM is running on this host
Connected to domain HostedEngine
Escape character is ^]
error: internal error: cannot find character device <null>
I tried to boot it from cdrom by changing vm.conf file and I'm not sure if
the syntax is correct:
1. I removed bootOrder:1 from the index:0 device
devices={index:0,iface:virtio,format:raw,address:{type:pci,slot:0x07,bus:0x00,domain:0x0000,function:0x0},volumeID:8d823e33-4260-4004-a468-cf477d7b1f5b,imageID:41342181-5c8f-4544-878b-44fdaa40dddc,readonly:false,domainID:beb954e7-61b7-4437-bd21-4b268e1a26e5,deviceId:41342181-5c8f-4544-878b-44fdaa40dddc,poolID:00000000-0000-0000-0000-000000000000,device:disk,shared:exclusive,propagateErrors:off,type:disk}
2. in index:2 device I addedd bootOrder:1 and path to the iso image:
devices={index:2,iface:ide,shared:false,readonly:true,bootOrder:1,deviceId:8c3179ac-b322-4f5c-9449-c52e3665e0ae,address:{controller:0,target:0,unit:0,bus:1,type:drive},device:cdrom,path:/opt/iso/CentOS-7-x86_64-DVD-1804.iso,type:disk}
The outcome is the same - no console connection.
Now I also get:
hosted-engine --vm-start
Command VM.getStats with args {'vmID':
'1e3aa9cf-8708-40a0-bc86-1127df01047a'} failed:
(code=1, message=Virtual machine does not exist: {'vmId':
u'1e3aa9cf-8708-40a0-bc86-1127df01047a'})
Unfortunately I do not have any backup. Is there a way to redeploy hosted
engine and import current configuration or any other way to fix it?

I'm using a proxy server - might that cause this problem? If so - where in the different (sub)playbooks would I have to set the environment variable?

How to force a QoS IO limit update to all disks
by Florian Schmid
Hi,
oVirt version: 4.2.5.1
I have a strange problem with IO limiting.
I have a storage domain for our dev environment and I have set the default Disk Profile to a QoS rule with IO limit enabled.
This rule is working so far, but when I change the QoS rule of this default Disk Profile to a different IO limit, all the disks have still the old limit active.
Only when I edit the disk and click OK without changing anything, I see also in Events, that the new IO limit is set.
This behavior would cause me a lot of work, because we have several 100s of disks and I can't edit all, only to have new QoS active.
Is there another way to do this bulk change of disk IO limit?
What data do you need to have a look on?
EDIT:
I saw now, that the QoS policy is automated updated on some VMs and there only on some disks, but not on all. Is there a rate limit active or so?

nested item with ovirt_vm_facts ansible module
by Nathanaël Blanchet
I try to get a list for all vms :
"vm_name : description : id "
A simple loop works:
- debug:
msg: "{{ ovirt_vms | map(attribute='snapshots') | list }}"
register: snapshotid2
tags: snapshots2
- debug:
msg: "{{ ovirt_vms | map(attribute='name') | list }}"
register: name2
tags: snapshots2
- set_fact:
toto: "{{ name2.msg[item] }} : {{
snapshotid2.msg[0][0].description }} : {{ snapshotid2.msg[0][0].id }} "
with_item:
- 0
- 1
register: all_snapshots2
tags: snapshots2
- debug:
var: all_snapshots2
tags: snapshots2
Now I want insert a second loop with "with_nested" like so:
- set_fact:
toto: "{{ name2.msg[item.1] }} : {{
snapshotid2.msg[0].item.0.description }} : {{
snapshotid2.msg[0].item.0.id }} "
with_nested:
- [ '0', '1']
- [ '1', '0']
but I always have this error: "The error was: 'list object' has no
attribute u'0'"
How can I do such a thing?

Ovirt and Foreman integration failure to provision
by 0pk0de＠riseup.net
Hello,
I am trying to integrate ovirt and foreman, foreman is able to create VMs but fails to provision them correctly (image/template based). The IP address does not get set to the correct one, cloud-init doesnt run either since the password is not correct after booting.
My questions are the following:
1. how does the normal provisioning setup looks like (using image/template)? I assumed it would just provision it depending on my puppet classes after booting, is this incorrect?
2. What does foreman *need* from ovirt? does it need a template that for example already has puppet installed? I assumed this was not the case...
3. How is it possible to initially "seed" the vm with the puppet master details when not using cloud-init (which seems optional), what magic can make this happen behind the scenes? is it something like libguestfs? Can I just use a cloud glance image like "centos 7 generic cloud v1805" and import that as a template and then create a host on foreman using this template? and then it should provision it?

Single Node oVirt and Gluster Hyperconverged
by Jeremy Tourville
I have a question about this specific prerequisite-
* You must have at least 2 interfaces on the host, so that the frontend and backend traffic can be separated out. Having only one network will cause the engine monitoring, client traffic, gluster I/O traffic to all run together and interfere each other. To segregate the backend network, the gluster cluster is formed using the backend network addresses, and the nodes are added to the engine using the frontend network address.
>>>You must have at least 2 interfaces on the host, so that the frontend and backend traffic can be separated out.>>>This part is very clear to me. You need at least 2 NICs.
>>>Having only one network will cause the engine monitoring, client traffic, gluster I/O traffic to all run together and interfere each other.

What is not clear to me is, do you need to have the IPs in different subnets or can they be in the same subnet?
For reference, I was able to set this up with two IPs in the same subnet and it does seem to work. However, I have noted some slowness issues while connecting storage domains during startup and frequently get messages about needing to restart the HA agent. Usually it seems after I try to restart services I can get the system to recognize the engine storage domain and start the engine. I wonder if my problem is the fact that both my front and backend IPs are in the same subnet? Thanks for your advice.

Re: ovirt-engine-extension-aaa-ldap-setup failed
by Jeremy Tourville
The backend is 389 DS, no this is not Govt related. This will be used as a training platform for my local ISSA chapter. This is a new 389 DS server. I followed the instructions at https://www.unixmen.com/install-and-configure-ldap-server-in-centos-7/
The server is "stock" with the exceptions of the settings for startTLS and adding certificates, etc (basically, whatever is needed to integrate with the Ovirt Engine.)
I am using my Admin account to perform the bind. What I don't understand is why everything else in the aaa setup script works except the login sequence. It would seem like my certificates are correct, correct use of the admin DN, etc. The funny part is I can login to the server using the admin account and password yet the same admin account and password fail when using the aaa setup script. But, that is why I am using the expert knowledge on the list! Maybe I have overlooked a simple prerequisite setting needed for setup somewhere?
I'll wait for someone to chime in on possible reasons to get this message:
SEVERE Authn.Result code is: CREDENTIALS_INVALID
[ ERROR ] Login sequence failed

Separating VM network
by d.gengenbach＠patagona.de
We would like to separate our VM traffic completely from our host/storage network. As far as I can see, there is no definitive guide to achieve this by using VLANs/separate VM networks/subnetting.
In our current setup:
- the storage traffic happens in a separate VLAN (configured directly on the switch) on separate NICs on both hosts/storages in the 192.168.179.0/24 subnet
- all other infrastructure (oVirt hosts, gateway, DHCP, DNS, VM thinclients, switches, ...) are in the 192.168.178.0/24 subnet
We now want to separate the oVirt hosts/engine completely from the other infrastructure, eg. the VMs and thinclients.
I am not experienced in networking and would be very thankful for all hints/tipps!
Thanks in advance,
David
