I can't call it "resolved" , but it's up to you.
I would look at gluster logs for clues.

Once the KVM host is part of an oVirt cluster, many interactions come from the 
VDSM service.
It would help if you used a different KVM host for this kind of procedure.

If so, can I still run it on KVM Server fn the oVirt platform?
It seems that a lot of oVirt's configuration information is not stored in 
QUEMU's configuration file like ordinary KVM SERVER, but in the database. Does 
this still work?

Yes, ovirt manages your environment and such does for you some of the 
operations to ease you from doing it manually.
When you create a template in ovirt you may or may not set the sealing option. 
In the bottom line it will run virt-sysprep with the parameters we thought are 
right.
Note the documentation in the thread, for windows OS you will need to do it

[ovirt-users] ovirt-image-repository is unattached

2021-08-24 Thread eevans 
I had a gluster issue and got it resolved, but now the ovirt-image-repository 
is unattached in the storage domain section. I was able to import the images 
but want to make sure its something that just points to another problem I don't 
know about.

Any help is appreciated.

[ovirt-users] Re: [External] : about the network name rules on CentOS/Redhat 8 and the cloud-init network interface name

2021-08-24 Thread Marcos Sungaila 
You have two options:
- If installing the VM using a pxe environment/network server,  you can add 
this options as kernel_extra boot options at the Run Once install procedure.
- if installing the VM using an ISO image, edit the install menu entry and add 
this option at the end of line.

The naming convention is called BiosDevName and was introduced in kernel 
2.6.27. It is defined by the OS kernel you are using in the guest. It is not 
related to oVirt itself or the KVM host.
In my case, I install my VMs passing "biosdevname=0 net.ifnames=0" during the 
OS installation process, so all my VMs have ethX name style to make it easier 
to use cloud-init and other scripts.

Everybody is good!
As you all know, to use the client's network card name in cloud-init, you must 
fill in the exact name of the network card interface. 
This was easy in version 7 and before, which usually started with EN0. 

After version 8, however, the naming conventions for network cards changed a 
lot. In my own test environment, for example, I started with ENS3.
I'm not sure what naming convention it uses, which would make it impossible to 
specify nic information using cloud-init. 

Could you help me explain how to deal with this problem?
Thank you very much!

2021-08-24 Thread Marcos Sungaila 
One important thing, you run the virt-sysprep command on the KVM host 
indicating the VM name to seal, you do not run it inside a VM.
It is not like the sysprep command on a Windows machine.

Yes, ovirt manages your environment and such does for you some of the 
operations to ease you from doing it manually.
When you create a template in ovirt you may or may not set the sealing option. 
In the bottom line it will run virt-sysprep with the parameters we thought are 
right.
Note the documentation in the thread, for windows OS you will need to do it 
manually.

I am using 4.4.5 and I tried all that but couldn't get it to work. In the
end I created another storage domain and moved all VMs to it.

@shani : Thanks for that.

But where to set in on oVirt Platform when I create the VM ?

The naming convention is called BiosDevName and was introduced in kernel
2.6.27. It is defined by the OS kernel you are using in the guest. It is not
related to oVirt itself or the KVM host.
In my case, I install my VMs passing "biosdevname=0 net.ifnames=0" during
the OS installation process, so all my VMs have ethX name style to make it
easier to use cloud-init and other scripts.

Everybody is good!
As you all know, to use the client's network card name in cloud-init, you
must fill in the exact name of the network card interface. 
This was easy in version 7 and before, which usually started with EN0. 

After version 8, however, the naming conventions for network cards changed a
lot. In my own test environment, for example, I started with ENS3.
I'm not sure what naming convention it uses, which would make it impossible
to specify nic information using cloud-init. 

Could you help me explain how to deal with this problem?
Thank you very much!

specify nic information using cloud-init. 

 

Could you help me explain how to deal with this problem?

Thank you very much!

Hi,

 

this is called Predictable Network Names and it is the default policy for net 
interface naming in el8. There are a couple tricks you can do to mitigate that,

you can disable it, or predict the name based on your configuration PCI slot 
etc [0]. There is a documentation for RHEL that explains it [1].

There is also another option and that's using a custom udev rule to assign 
whatever name you want based on some identifiers like MAC, PCI addr etc.

 

Hopefully this helps.

 

Best regards,

Hiya,

The API in oVirt engine actually supports creating snapshots etc. for backups. 
Check out github for scripts, i.e.:

https://urldefense.com/v3/__https://github.com/luisperezmarin/oVirtVMBackup__;!!ACWV5N9M2RV99hQ!aLktcN2ZyTyy0Qa70UDbLPzKdU3VKYHfL6zBVWy0NNo0M8tkjN1NVxSDMfDmLnboxA8$
 

And there are others.

There is also a commercial solution, Storware vProtect:

And as far as backup systems go, bareos(open source) is an ok solution, and it 
also support oVirt:

[ovirt-users] Re: [External] : about the network name rules on CentOS/Redhat 8 and the cloud-init network interface name

2021-08-24 Thread Marcos Sungaila 
The naming convention is called BiosDevName and was introduced in kernel 
2.6.27. It is defined by the OS kernel you are using in the guest. It is not 
related to oVirt itself or the KVM host.
In my case, I install my VMs passing "biosdevname=0 net.ifnames=0" during the 
OS installation process, so all my VMs have ethX name style to make it easier 
to use cloud-init and other scripts.

Everybody is good!
As you all know, to use the client's network card name in cloud-init, you must 
fill in the exact name of the network card interface. 
This was easy in version 7 and before, which usually started with EN0. 

After version 8, however, the naming conventions for network cards changed a 
lot. In my own test environment, for example, I started with ENS3.
I'm not sure what naming convention it uses, which would make it impossible to 
specify nic information using cloud-init. 

Could you help me explain how to deal with this problem?

[ovirt-users] Re: Resize iSCSI LUN and Storage Domain

2021-08-24 Thread Shani Leviim 
Hi Shantur,
The "Additional Size" column mentioned was merged with the 'add' column, so
the new column is called 'Actions' [1].
(manage domain while the sd is active).

There's also an option to refresh the LUNs size while the VM is up and
running (available since version 4.4.5) [2].
It also has a short demo for showing the refresh [3]

[ovirt-users] Re: [External] : Re: Template for Ubuntu 18.04 Server Issues

2021-08-24 Thread Marcos Sungaila 
Hi Miguel,

The virt-sysprep command seals a VM when building it on a standalone KVM host. 
Creating a template using the Make Template option in the VMs page 
automatically seals the VM during this process.
Anyway, in a standalone KVM host, gracefully shut down the VM and run the 
command as follows:

# virt-sysprep -d

Marcos

I have seen the same problem. Even confirmed that MAC address are different on 
VM's. I am using a DSHP server.

How do you use the virt-sysprep command? is executed from ovirt-master / vm? 
how do you select the template though?

I'm at the same point as you, not sure if this is expected behave or missing 
something.

[ovirt-users] Re: Backup to tape

2021-08-24 Thread duparchy 
Hi, 
thanks for the links. We'll check.

We already have snapshoting at the iSCSI storage array level (Compellent), 
together with replication between storage arrays. 
We have online a rolling 7 days snapshots + replicats.
 
Of course, these are inconsistent snapshots. But from the numerous tests we've 
done during the past 10 years (in the context of Oracle VM) we never ever 
bumped into a VM that would not restart from what is a crash, from the VM point 
of view. If it occurs, we can try with the day before . We have online a 
rolling 7 days snapshots + replicats.

Of course we'll consider synchronising oVirt snapshots with Storage replication 
and snapshot. 

Mounting a storage array snapshot and pipe dd over ssh to restore a VM is not a 
big deal and we don't feel the need of an additional product for that.

I've tested the following  : 
- Activate source and destination partitions
Source : lvchange -ay 
337efd74-b261-4855-b78c-5b28943df889/a01f9f37-9fe9-43b4-88e6-c2eb9470295e 
Destination : lvchange -ay 
337efd74-b261-4855-b78c-5b28943df889/a01f9f37-9fe9-43b4-88e6-c2eb9470295e 
- Restore the partition
dd 
if=/dev/337efd74-b261-4855-b78c-5b28943df889/a01f9f37-9fe9-43b4-88e6-c2eb9470295e
 bs=1M | ssh 192.168.235.218 dd 
of=/dev/337efd74-b261-4855-b78c-5b28943df889/a01f9f37-9fe9-43b4-88e6-c2eb9470295e
 bs=1M status=progress conv=sparse
- deactivate the destination
lvchange -an 
337efd74-b261-4855-b78c-5b28943df889/a01f9f37-9fe9-43b4-88e6-c2eb9470295e

Part of Disater Recovery Plan, we also need offline backups, to tape. Up to now 
we weekly tar the img files, taken from a storage array snapshot, to a LTO, and 
voila. Now Working with LVM partition, dd seems appropriate, except that we are 
loosing granularity. We'll backup everything and it'll take more time.

I've tested the following and it seems OK to backup to tape an entire iSCSI LUN

dd if=/dev/mapper/36000d310012f4a00021d of=/dev/nst0 bs=1M 
status=progress

I was just wondering if conv=sparse at the device level (iSCSI LUN) may break 
things or not.

Hi Shantur

what version of ovirt you are using? what is the storage model? try to perform 
scan by selecting the storage domain that you have resized at the storage side. 
if that is not help, add new storage domain and perform discovery one more time 
and see whether it can be discovered 

extending the storage domain size can be done in fly, no maintenance required.

[ovirt-users] about the network name rules on CentOS/Redhat 8 and the cloud-init network interface name

2021-08-24 Thread Tommy Sway 
Everybody is good!

As you all know, to use the client's network card name in cloud-init, you
must fill in the exact name of the network card interface. 

This was easy in version 7 and before, which usually started with EN0. 

 

After version 8, however, the naming conventions for network cards changed a
lot. In my own test environment, for example, I started with ENS3.

I'm not sure what naming convention it uses, which would make it impossible
to specify nic information using cloud-init. 

 

Could you help me explain how to deal with this problem?

Thank you very much!

[ovirt-users] Re: Backup to tape

2021-08-24 Thread Tony Brian Albers 
Hiya,

The API in oVirt engine actually supports creating snapshots etc. for 
backups. Check out github for scripts, i.e.:

https://github.com/luisperezmarin/oVirtVMBackup

And there are others.

There is also a commercial solution, Storware vProtect: 
https://storware.eu/products/vprotect/

And as far as backup systems go, bareos(open source) is an ok solution, 
and it also support oVirt: https://www.bareos.com/

[ovirt-users] Correct way to install VDSM hooks

2021-08-24 Thread Shantur Rathore 
Hi all,

I am trying to install vdsm hooks (scratchpad) specifically.
I can see that there are rpms available in
https://resources.ovirt.org/pub/ovirt-4.4/rpm/el8/noarch/ but when I try to
install using yum it says it cannot find it.
Do I have to manually select the hook rpm and install it or am I missing
something?

Kind regards,
Shantur

[ovirt-users] Re: Impossible to move disk after a previous disk move failed

2021-08-24 Thread Benny Zlotnik 
c23a5bef-48e0-46c7-9d5b-93c97f0240c0 is the target storage domain?
if the disk is still on the source storage domain in ovirt-engine, you
can remove the LV manually with lvremove, after making sure the source
is correct with
$ vdsm-client Volume getInfo

Do you know why the move failed? When move fails it should cleanup the
target (unless there was no access to the storage)

[ovirt-users] Backup to tape

2021-08-24 Thread duparchy 
Hi, 

Part of our Disaster Recovery Plan we do tape backup.

Our previous infrastructure was Oracle VM and VMs fisk were files (.img) we 
could apply filters to our tar and backup to tape only required files.

Now preparing the migration to Oracle flavor of oVirt (OLVM).  
VMs disks are LVM partitions, within  an iSCSI LUNs.

I've tested "dd" to backup  the entire iSCSI LUN to the tape. Seems OK 
,providing the right block size we achieve reasonable performances.
Though I don't quite see how to have that granular backup we had, in a simple 
manner, which a goal too.

Although there is compression at the LTO level, the dd conv=sparse parameter 
may speed-up things. To be tested.
I'm just wondering if conv=sparse may breaks things at the LVM / qcow2 
containers ?
