[ovirt-users] ovirt terraform - multiple nics creation problem

[marek]

i have problem with creation VM with multiple nics

part of terraform config

resource "ovirt_vm" "vm" {

  initialization {
    authorized_ssh_key = "${var.vm_authorized_ssh_key}"
    host_name  = "${var.vm_hostname}"
    timezone   = "${var.vm_timezone}"
    user_name  = "${var.vm_user_name}"
    custom_script  = "${var.vm_custom_script}"
    dns_search = "${var.vm_dns_search}"
    dns_servers    = "${var.vm_dns_servers}"

    nic_configuration {
  label  = "eth0"
  boot_proto = "${var.vm_nic_boot_proto}"
  address    = "${var.vm_nic_ip_address}"
  gateway    = "${var.vm_nic_gateway}"
  netmask    = "${var.vm_nic_netmask}"
  on_boot    = "${var.vm_nic_on_boot}"
    }

    nic_configuration {
  label  = "eth1"
  boot_proto = "${var.vm_nic2_boot_proto}"
  address    = "${var.vm_nic2_ip_address}"
  gateway    = "${var.vm_nic2_gateway}"
  netmask    = "${var.vm_nic2_netmask}"
  on_boot    = "${var.vm_nic2_on_boot}"
    }
  }
}

resource "ovirt_vnic" "eth0" {
  name    = "eth0"
  vm_id   = "${ovirt_vm.vm.id}"
  vnic_profile_id = "${data.ovirt_vnic_profiles.nic1.vnic_profiles.0.id}"
}

resource "ovirt_vnic" "eth1" {
  name    = "eth1"
  vm_id   = "${ovirt_vm.vm.id}"
  vnic_profile_id = "${data.ovirt_vnic_profiles.nic2.vnic_profiles.0.id}"
}


how terraform knows which nic_configuration {} from ovirt_vm belongs to 
which resource "ovirt_vnic"?


my problem is that VM has paired nic_configuration(eth0) with resource 
"ovirt_vnic" "eth1" and vice versa


any hints?


https://github.com/oVirt/terraform-provider-ovirt/blob/master/ovirt/resource_ovirt_vm.go#L967
my experience with Go is not enough to understand how is "pairing" done

Is this about updating oVirt docs based on what we have
documented downstream? Downstream we had to target 4.4.2 with incremental
backup updates due to a large number of 4.4.1 priorities. 

https://www.ovirt.org/documentation/incremental-backup-guide/ doesn't even
seem to be linked from https://www.ovirt.org/documentation -- maybe we
should just unpublish it?

Thanks,

[ovirt-users] Problem with backuping ovirt 4.4 with SDK

[Łukasz Kołaciński]

Hello,

I am trying to do full backup on ovirt 4.4 using sdk. I used steps from this 
youtube video: https://www.youtube.com/watch?v=E2VWUVcycj4 and I got error 
after running backup_vm.py. I see that sdk has imported disks and created 
backup entity and then I got sdk.NotFoundError exception. I also tried to do 
full backup with API and after finalizing backup disappeared (I think) and I 
couldn't try incremental.

[ovirt-users] Strange SD problem

HI,

I'm having a strange behavior with a SD. When trying to manage the SD I see 
they "Add" button for the LUN which should already be the one use for that SD.
In the Logs I see the following:

It looks like the engine will add a LUN to an SD and it already exist...
Any Idea how to resolve that problem?

Thanks a lot

[ovirt-users] iSCSI multipath with separate subnets... still not possible in 4.4.x?

[Mark R]

I'm looking through quite a few bug reports and mailing list threads, but want 
to make sure I'm not missing some recent development.  It appears that doing 
iSCSI with two separate, non-routed subnets is still not possible with 4.4.x. I 
have the dead-standard iSCSI setup with two separate switches, separate 
interfaces on hosts and storage, and separate subnets that have no gateway and 
are completely unreachable except from directly attached interfaces.

The hosted-engine comes up with multiple paths and everything is perfect, but 
that's because Ansible/hosted-engine deploy script have configured things 
correctly.  Once you need to import or add new storage domains, it's not 
possible to do so in a way that gets both paths connected *and* persists across 
host reboots. Following the docs to create 'iSCSI Multipath" bonds (plural, you 
can _not_ create a single bond that includes both interfaces and hope things 
route correctly... oVirt will try to connect from the interface for storage 
network A to the target on storage network B, which can't happen since they are 
not routed (and should not be). So, there's nothing in the docs about how you 
can accomplish multipathing, but there are a few mailing list messages that say 
"just create two separate "iSCSI Multipath" bonds in the datacenter, one for 
each of your two interfaces. You can do this, and you'll get hopeful that 
things might work now. You can do discovery and it succeeds, because no
  more trying to connect to unreachable targets. However, and big caveat, 
there's no way to tell this new/imported domain, "Oh, use this other interface 
as well, so you have redundant paths". Once the domain is attached and 
activated, you have a single path. You can then manage the domain, do a 
discovery, see a path that isn't connected yet, and log into it as well. Now 
you have two paths, is everything right with the world?!?  Nope, it's 
impossible to persist that connection, it will be gone on next reboot and 
you'll always have to manually visit each host, do discovery, and login. 
Nothing in the UI allows you to "Save" that second connection in a way that it 
will be used again. Clicking "OK" does not, and going back to the "iSCSI 
Multipath" area of the Data Center you can't edit each of the bonds and make 
sure each logical network has every possible target checked, because these 
targets you've manually logged into are never listed in that area of the UI.

So I really, really hope I'm wrong because I'd like to move past this snag and 
onto the next one (which is that bond interfaces in 4.4.x will not allow you to 
attach additional networks... works great in 4.3, appears broken in 4.4.x). 
But, no sense chasing that yet if iSCSI multipath isn't possible, which is 
looking likely.

Has anyone had success, running iSCSI in by far the most common setup out 
there, but also in a way oVirt really doesn't want to let you? This is driving 
me nuts, I've paved and rebuilt these hosts dozens of times now, trying 
different methods in the hopes of getting multipath that persists.

[ovirt-users] oVirt Node 4.4.1.1 Cockpit Hyperconverged Gluster deploy fails insufficient free space no matter how small the volume is set

[clam2718]

Hi,

Deploying oVirt 4.4.1.1 via Cockpit --> Hosted Engine --> Hyperconverged fails 
at Gluster deployment:

TASK [gluster.infra/roles/backend_setup : Create thick logical volume] *
failed: [fmov1n3.sn.dtcorp.com] (item={'vgname': 'gluster_vg_nvme0n1',

Deployment is on 3 count Dell PowerEdge R740xd with 5 count 1.6TB NVMe drives 
per host.  Deployment is only to three as JBOD, 1 drive per node per volume 
(engine, data, vmstore) utilizing VDO. 
 Thus, deploying even a 100G volume to 1.6TB drive fails with "insufficient 
free space" error.

I suspect this might have to do with the Ansible playbook deploying Gluster 
mishandling the logical volume creation due to the rounding error as described 
here: 
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/6/html/logical_volume_manager_administration/nofreeext

If I can provide any additional information, logs, etc. please ask.  Also, if 
anyone has experience/suggestions with Gluster config for hyperconverged setup 
on NVMe drives I would greatly appreciate any pearls of wisdom.

Thank you so very much for any assistance!
Charles

Personally I find the rhev documentation much more complete:

[ovirt-users] how to get ovirt 4.3 documentation?

[Philip Brown]

I find it odd that the ovirt website allows to see older version RELEASE 
NOTES...
but doesnt seem to give links to general documentation for older versions.
For example, if you read 

https://www.ovirt.org/release/4.3.10/
it says, 

"For complete installation, administration, and usage instructions, see the 
oVirt Documentation."

but that links to the general docs page at https://www.ovirt.org/documentation/

It does NOT link to any ovirt 4.3 docs, which is what I actually need

Sorry, this is already documented also on engine side:

# Configuration overrides for ovirt-engine.
#
# WARNING: This file owned by ovirt-engine. If you modify this file your
# changes will be overwritten in the next ovirt-engine upgrade.
#

# This example overrides ca_file to be empty string. This can be useful if

There are some typos but it is very clear.

It is not related to imageio configuraion in any way, but yes, this
document is not
ready and needs update.

We have this bug to replace it:

If that's the case probably better to unpublish: no point in providing
broken documentation.
We can re-publish once we have the fixed one.

Looks like you're having some issue validating the SSL certificate served
through the proxy.
You can read more about it here https://curl.haxx.se/docs/sslcerts.html
If you have more than 3 hosts I would consider using foreman / satellite
smart proxy function (if you don't need more from foreman / satellite)

We have an open ticket about it here:

You can try using one of the mirrors:
https://resources.ovirt.org/pub/yum-repo/mirrorlist
One of them may have IPv6 enabled.

oVirt doesn't support running hosted engine deployment as non-root user.

yes the recomendation is to run again the deployment from scratch, the
cleanup tool has no guarantee to remove everything from the host so it may
have some file left around on the system.

Right, you need to change the ovirt-imgeio configuration to replace the CA.

But note that you should not touch:

/etc/ovirt-imageio/conf.d/50-engine.conf

This file is owned by engine and your changes will be dropped silently
on the next
upgrade.

You need to add your own configuration file, maybe:

/etc/ovirt-imageio/99-local.conf

Where you can override what you need:

[tls]
ca_file = ...

This is documented in the top of 50-vdsm.conf:

# Configuration overrides for vdsm.
#
# WARNING: This file owned by vdsm. If you modify this file your changes will
# be overwritten in the next vdsm upgrade.
#
# To change the configuration create a new drop-in file with a higher prefix,
# so your setting will override vdsm and builtin configuration:
#
# $ cat /etc/ovirt-imageio/conf.d/99-locl.conf
# [logger_root]
# level = DEBUG
#
# This example overrides ovirt-imageio service log level to DEBUG.

But the documentation is missing on engine side.
Please file engine bug for this.

Please file ovirt-imageio Documentation bug for this.

[ovirt-users] ovirt 4.4 installation issues

[Markus Schaufler]

Hi all,
in our environment, CentOS7 and RHEL7 for the most part (Ovirt 4.3 and RHV 
4.3), we are able to set a proxy directly in /etc/yum.conf (or on the single 
repo) to momentarily bypass some network restrictions.
The proxy settings looks like this:
proxy=http://our-proxy.domain:8080
proxy_username=user
proxy_password=password

But is also works properly when it is set directly from CLI, and this is the 
one we use more often:
export http_proxy=http://user:password@our-proxy.domain:8080
export https_proxy=https://user:password@our-proxy.domain:8080

We are having difficulties to set the same proxy on CentOS8 / Ovirt 4.4.x.
There is no way the proxy settings allows us to run "yum update".

Extra Packages for Enterprise Linux 8 - x86_64  
 
0.0  B/s |   0  B 00:00
Errors during downloading metadata for repository 'ovirt-4.4-epel':
  - Curl error (56): Failure when receiving data from the peer for 
https://mirrors.fedoraproject.org/metalink?repo=epel-8&arch=x86_64&infra=stock&content=centos
 [Received HTTP code 407 from proxy after CONNECT]
Error: Failed to download metadata for repo 'ovirt-4.4-epel': Cannot prepare 
internal mirrorlist: Curl error (56): Failure when receiving data from the peer 
for 
https://mirrors.fedoraproject.org/metalink?repo=epel-8&arch=x86_64&infra=stock&content=centos
 [Received HTTP code 407 from proxy after CONNECT]

Can somebody maybe point us to a solution? The above command is extracted by 
'yum update' after a clean installation of Ovirt 4.4.1-2020070811 (but the same 
issue happened on previous versions and Nightly versions too).

Thank you,
Markus

Did you register the system with subscription manager?
As a quick reference, before enabling modules on RHEL you'll need:

# subscription-manager register
# subscription-manager attach --pool=pool_id
# subscription-manager repos \
--enable=rhel-8-for-x86_64-baseos-rpms \
--enable=rhel-8-for-x86_64-appstream-rpms \
   --enable=codeready-builder-for-rhel-8-x86_64-rpms

In CentOS we are consuming also PowerTools repo which should correspond
to codeready-builder-for-rhel-8-x86_64-rpms if I remember correctly.

[ovirt-users] Re: Admin portal will not load after installing updates

[Michael Watters]

Thanks for the response.  The issue was that I had to run engine-setup
after running yum updates.  The rpms do not appear to do this or tell
you that you need to run the command.  :)

[ovirt-users] Ovirt 4.4.1 Install failure at OVF_Store check

[AK via Users]

I am trying to freshly install oVirt 4.4.1 with HCI on CentOS 8.2.  I am using 
the "hosted-engine --deploy" script and the installation fails at "Check the 
OVF Store"  consistently.  I did try to apply the fix loaded on Jenkins 
(https://jenkins.ovirt.org/job/ovirt-hosted-engine-setup_standard-check-patch/183/)
 which produced the same result. 

Any help is appreciated and I ma working to attached the install log.  

Thanks

[ovirt-users] Revert to 4.3

[jb]

Hello everybody,

at to moment I run ovirt engine in a VM on a different server (no hosted 
engine) and I have two hosts. One is only a backup and is not running.


I would like to install a new ovirt engine 4.4 VM and use the backup 
host. And if this is running fine in some month I would migrate the 
second host to 4.4.


The Problem is only that I have to upgrade the data center compatibly 
mode to 4.4 and with that I'm a bit afraid.


Is it possible, to downgrade the compatibility mode, when something 
unsuspected is happen?


The original 4.3 engine VM I would like to have untouched, that I can go 
back if is necessary.



Regards

Jonathan
