[ovirt-users] Re: Asking about snapshot concept

[Eyal Shenitzky]

Hey Terry,

When creating a snapshot it causes a new COW layer to be created over the
current layer.
All write actions performed after a snapshot is taken are written to the
new COW layer.

The format that supports the option of "growable" disks is sparse,
therefore, when creating a snapshot of the disk, the format must support
the option to add another layer and maintain the difference between them.

Regard to the snapshot size, it should contain all the changes between
the "old" disk layer (the snapshot) and the new layer (active snapshot) and
in order to achieve that, we should be able to mark each diff (note that
this is a qcow2 disk and not all the space is allocated).

You can look and search for another information here -

[ovirt-users] Asking about snapshot concept

[Terry hey]

Dear all,

I have a pre-allocated virtual machine.
When i created a snapshot for that virtual machine, i found that it became
thin-provision.
And the size of the snapshot is same as the virtual machine.
i would like to ask why these two behavior happened.
1. preallocated to thin provision
2. the size of snapshot is same as the disk size of virtual machine.

[ovirt-users] Re: Unable to start VM on host with OVS networking

[Sverker Abrahamsson]

In my setup the reason why I attempted to use OVS/OVN is that I 
(currently) have two hosts in a data center (Hetzner) which does not 
have a common subnet. Each of these hosts have one public IPv4 address.


Because of that I want the ovirt networks to be on private ip ranges and 
they do not correspond to any physical network interfaces. I've been 
able to work around that by making dummy interfaces visible for vdsm to 
which it can bind the ovirtmgmt bridge.


It also means that I need to connect the obirtmgmt bridges on the two 
hosts with tunnels. With OVS I can set that up manually and it works 
great, issue is that vdsm wants to control the network interfaces and 
creates an OVS bridge with random name to attach ovirtmgmt port to, 
hence I have no convenient way to connect these bridges. I could put a 
hook in after_network_setup to create tunnels, but I suppose the OVS 
bridges needs to have the same name on both sides.


I want to use ovirt for a test environment with quite complex network, 
hence why OVN is desired to be able to set it up virtual.


With OVN + physnet as you describe it I assume I should get the desired 
functionality as ovirtmgmt needs to be present on all hosts. Since you 
disabled changing switch type in engine gui I changed it in db, don't 
know if anything more is needed, and in the vdsm persistent file. On 
vdsm level that works fine, the OVS bridge with random name is created 
with ovirtmgmt port, but as you write since 4.2.3 it no longer creates 
the port for hosted engine on the OVS bridge. I worked around that with 
a hook script that add the missing elements to interface section of the 
vm xml.


My understanding is that for OVN+physnet then OVS switch is needed but 
doesn't then the ovirtmgmt port has to be on an OVS bridge? If so then 
hosted engine must be able to connect it's port to the same bridge.


Next concern is where should the OVN databases be? With hosted-engine 
setup they are created on the vm which seems like a chicken and the egg 
issue to me as how could the hosts where ovn-controller runs be able to 
connect to db before the vm has started? In my setup the vm only have 
private address which means the other host is not able to reach ovn 
database until the virtual network has established.


Therefore I created OVN databases on one of the hosts, and configured 
with ssl cert/keys so that they are able to communicate fine. I 
configured ovirt-provider-ovn running on hosted engine vm to connect to 
the db host but even when ovn-remote is set to the correct address on 
the host the requests from ovirt-provider-ovn towards port 6641 still 
goes to the engine vm.


Are there any additional steps that is needed to take?

Den 2018-05-25 kl. 17:41, skrev Dan Kenigsberg:

I believe the user community deserves a little background for this
decision. OVS has been "experimental" since ovirt-4.0.z with migration
disabled by default. We were not aware of huge benefits it had
over the default Linux bridge, and did not expect people to be using
it in important deployments.

I would love to hear your experience regarding our OVS support, and
why you have chosen it.

In ovirt-4.2.0, the way in which VM libvirt definition is built has
changed considerably, and takes place in ovirt-engine, not in vdsm.
The vdsm code that supports OVS connectivity was disabled in
ovirt-4.2.3 which means that indeed, the experimental OVS feature is
no longer available for direct usage (unless you still use cluster
compatibility level 4.1)

However, as Thomas Davis explains, with OVN + physnet, ovirt-4.2 gives
you a matching functionality, including live migration out-of-the-box.
OVS switchtype was upgraded from "experimental" to "tech-preview". I'd
like to drop the advisory altogether, but we keep it because we still
have bugs and
missing features comparing to Linux bridge clusters.

We've blocked changing the switchtype of existing clusters because
this functionality is buggy (particularly on the SPM host), and as of
ovirt-4.2, we do not have code to support live migration from a Linux
bridge host to an OVS one. Only cold migration is possible. We kept it
open over REST to allow testing and bugfixes to that flow, as well as
usage by careful users.

Thanks for using oVirt and its new features, and for engaging with the
community.

Regards,
Dan.

The answer is..

OVN replaced OVS as the networking technology.  You cannot switch back to 
legacy, they disabled switching between ovs and legacy in the default (1st) 
datacenter using the gui.  You can however, use Ansible to switch it.

Remove the VDSM ovs setting, it will just mess you up, and it's not supported 
in 4.2

To able to migrate a VM in 4.2, you have use OVN with OVS.

I did this a few months back, on a 4.2.2 hosted-engine setup:

0) To setup a node in a cluster, make sure the cluster is in OVS, not
legacy.

1) Make sure you have an OVN controller setup somewhere.

 At the moment i would try the cinder storage provider, since we already

 ie: Specify the ceph monitors and ceph pool to connect to. Can oVirt
 directly connect to ceph monitors ? How the configuration should be done if
 so ?

If you execute hosted-engine-setup from CLI it will honor TMPDIR env
variable (with /var/tmp as default) but I don't think your issue is there
indeed your bootstrap engine VM was running.
Your issue was related to the execution of host-deploy code: host-deploy is
the code used to configure the host to be used as an hypervisor, the engine
copies it over ssh to the host under /tmp and executes it there so your
issue with noexec on /tmp.
I'm not aware of any way to customize host-deploy location.

No,

The only way you have is to configure cinder to manage ceph pool or in
alternative you have to deploy an iscsi gateway, no other ways are
available at the moment.

So you can't use rbd directly.

Hi
There is a BZ with a similar issue:
https://bugzilla.redhat.com/show_bug.cgi?id=1546839

To sum things up,  try stopping the network manager and restarting your network 
if you are using a RH distribution, e,g. :
systemctl stop NetworkManager
systemctl restart networkAnd check what is your kernel version.

Hi,

check what wrong with your **PATH**:

permissions, lvm, device-mapper, NFS, iSCSI, etc.

[ovirt-users] Bad volume specification

[Bryan Sockel]

Hi,

I am having to rebuild my ovirt instance for a couple of reasons.  I have 
setup a temporary ovirt portal to migrate my setup to while i rebuild my 
production portal.  

I have run int a couple of VM's that will no longer start.  

Everything that i am seeing is identical to this article - 
https://access.redhat.com/solutions/2423391

VM devel-build is down with error. Exit message: Bad volume specification

Currently running version 4.2.3.5-1

Is there anyway to recover the image, or even just be able to mount the 
drive to another vm to extract data.

Thank You

[ovirt-users] Re: Need advice using pacemaker on VMs for application HA

[wodel youchi]

Hi,

Thank you both for your responses,

In a conclusion :

- Don't mix up several solution that provide HA :
- either choose oVirt HA.
- or use software HA inside a VM.

And since I need to monitor a service inside the VM for HA purpose, the
implementation will be :
- Create two VMs (nodes) without oVirt HA enabled.
- Create the shared storage.
- Configure pacemaker with stonith using fence rhev.
- Test the configuration and my be try to test a hypervisor crash to see
the behavior of the solution.

Regards.

[ovirt-users] Hardering oVirt Engine

[Punaatua PK]

Hello,

we are subject to PCI-DSS. I have some questions. We currently have setup oVirt 
in our environnement.
We created 2 Datacenter.
- one with a cluster with hosted engine on gluster (Hyperconverged env) which 
represents the "LAN" part
- one with a cluster with gluster storage wich is the DMZ

In PCI-DSS we have to secure communication (use HTTPs as much as possible). I 
did saw that ovirt-ha-agent (on hosted-engine capable host) check the status of 
the engine by sending GET request on the hosted-engine on port 80 (the same 
check that hosted-engine --vm-status did in fact). 
Since ovirt 4.2.2, with the introduction of gluster eventing, a new flow (HTTP 
post resquest) is needed from gluster nodes to the engine. (In my case, it's a 
flow from the DMZ to the LAN part in HTTP (non secure)

Here is my question. Is it possible to "hardering" this part of the engine ?

Another question out of PCI scope. Events like warning and error in the 
dashboard are clean each days. I tried to find which process did that (look 
into /etc/cron.daily, root crontab, etc) on the engine
without succes. Is there any maintenance task that is run periodicaly ? Could 
we have the list of all the engine's task ? (regulary check the status of host, 
vm, storage) also the frequency ?

I would appreciate the help. (Great great product ovirt !) Thank you for your 
jobs ! We did manage KVM hypervisor as standalone machine without all the power 
that libvirt provides. No need to spend lot of money into licencing product 
(VSphere and co)

It seems to be a result of a bit naive behavior of the kvm2ovirt module
that tries to download only the top-level volume the VM uses, assuming each
of the disks to be imported is comprised of a single volume.

Maybe it's time to finally asking QEMU guys to provide a way to consume the
'collapsed' form of a chain of volumes as a stream if that's not available
yet? ;) It can also boost the recently added process of exporting VMs as
OVAs...

Does the template contain a NIC definition?

I assume more than one NIC is defined for the VM?

Can you ensure you are running with CentOS / RHEL 7.5? There was a bug in
cloud-init where it did not set the hostname due to some race. What do you
see in the cloud-init logs on the VM?
Y.

Hi

The provider_binding_host_id is a new table added recently , can you please
attach the output of the following query on your database :

select * from schema_version order by id desc;

Thanks

[ovirt-users] Problems with configuring ovirt and neotron network integration

[Pym]

Hi:


Environmental information：
 4.2.0 ovirt version, according to 
"https://www.ovirt.org/documentation/how-to/networking/overlay-networks-with-neutron-integration/;
 document of it services. Both services are accessible from the browser.


After the above environment is configured according to the document, I need to 
execute the following command "engine-config --set keyauthstoneurl =http://< 
host-fqdn >:35357/v2.0" on the ovirt-engine side.
The following information appears: "Error setting KeystoneAuthUrl's value. No 
such entry."


When I execute "engine-config-a | grep-i 'KeystoneAuthUrl'", there is no return 
value, and there is no such configuration item in the current version of ovirt.


Now how do I proceed next?

I do not think we have a documented procedure directly aimed at "making
sure everything is configured correctly", but a similar one is:

https://www.ovirt.org/documentation/how-to/migrate-pki-to-sha256/

It keeps the internal CA cert (only changes it), but re-creates all the
others.
