oVirt networks
by Enrico Becchetti
Dear all,
Ineed your help to understand how to configure the network of a new
oVirt cluster.
Mynew system will have a 4.3 engine thatruns in a virtual machine, andsome
Dell R7525 AMD EPYC hypervisors, eachholding two 4-port PCI network cards.
These servers will have node-ovirt image again in version 4.3.
As for the network, there are two HPE Aruba 2540G, non-stackable, with
24 1Gbs ports
and 2 10Gbs uplinks to the star center.
This is a simplified scheme:
My goal is to make the most of the server's 8 ethernet interfaces to have
both reliability and maximum possible throughput.
This cluster will have two virtual networks, one forovirt management and
one for
the traffic of individual virtual machines.
With that said here's what my idea is. I would like to have two links
aggregated by 4Gbs,
one for ovrtmgt and the other for vmnet.
With the ovirt web interface I can createan active-passive "Mode 1"
bond, but this
won'tallow me to go beyond 1Gbs. Alternatively I could create a "Mode 4"
bond
802.3ad but unfortunately the switches are not stacked and therefore not
even
this solution applies.
This is an example with active passive configuration:
Can you tell me if ovirt can generate//nested bonds? Or do you have
other solutions ?
Thanks a lot !
Best Regards
Enrico

boot from cdrom & error code 0005
by edp＠maddalena.it
Hi.
I have created a new storage domain (data domain, storage type nfs) to use it to upload iso images.
I have so uploaded a new iso and then attach the iso to a new vm.
But when I try to boot the vm I obtain this error:
booting from dvd/cd...
boot failed: could not read from cdrom (code 0005)
no bootable device
The iso file has been uploaded with success in the data storage domain and so the vm lets my attach the iso to the vm in the boot settings.
Can you help me?
Thank you

Importing VM from Vmware
by domenc＠gmail.com
Hi,
Migrating VMs from Vmware works nice in the UI but it's slow.
With https://blogs.oracle.com/scoter/post/how-to-migrate-vmware-vsphere-to-ora... i'm trying to import exported VM
virt-v2v \
–o rhv-upload \
–oc https://<OLVM-ENGINE-PORTAL>/ovirt-engine/api \
-op /root/olvm-admin-password-file \
-oo rhv-cacert=/root/ovirt-cacert.pem \
-oo rhv-cluster=<OLVM-CLUSTER> \
-os <OLVM_STORAGE_DOMAIN> \
-of qcow2 \
-oo rhv-direct \
--network <OLVM-NETWORK> \
-i libvirtxml <LOCAL-XML-FILE>
I tried everything possible but still there is an error
virt-v2v: error: no -oo (output options) are allowed here
If reporting bugs, run virt-v2v with debugging enabled and include the
complete output:
virt-v2v -v -x [...]
Any idea?

Problem with Glusterfs Distributed-Replicated volume almost full but only less than 50% used by files.
by Olivier
Hi,
I have a weird problem with my couple Glusterfs-oVirt:
I had two data domain for my VMs on oVirt. The main one (data) is a Distributed-Replicate with 2 x 3 = 6 bricks of ~ 1,4 Tb on 3 servers (2 bricks by server).
It was an extend of a previous 1 x 3 = 3 Replicated volume on the same servers. I had one new disk (and one new brick) on each of these 3 servers.
My concern is the reported use of this volume (almost 100%).
a df -h give me :
df -h .
Filesystem Size Used Avail Use% Mounted on
ovirt1.pmmg.priv:/data 3.4T 3.3T 84G 98% /rhev/data-center/mnt/glusterSD/ovirt1.pmmg.priv:_data
but a du of the same partition give me :
du -hs /rhev/data-center/mnt/glusterSD/ovirt1.pmmg.priv:_data
1.4T /rhev/data-center/mnt/glusterSD/ovirt1.pmmg.priv:_data
and there no hidden folder I could miss in this mount point.
The weird point (the second one) is when I delete a VMs and is disks (main disk and snapshot) I doesn't get back some space on these volume.
Does anyone have an idea of these problem ?
Thank's
Here the Info of the gluster volume :

Start VM with option -machine smm=off
by Kalil de A. Carvalho
Hello all.
I'm trying to workaround the problem reported here:
https://gitlab.com/qemu-project/qemu/-/issues/1198
but I did not find out how to start up the VM with the option -machine
smm=off like sead on the lsit above.
I guess that it is possible to run the command using the qemu command but I
think that I will lose the management of it.
It is possible to startup up a VM with this option using the oVirt GUI ou
virsh?
Best regards

New oVirt release ???
by Diggy
Any movement towards a new oVirt release now that CentOS Stream 8 is
officially at EOL and the current engine is based on it?
Do I see oVirt v4.6 in my near future? I'm looking for a reason to
build a fresh oVirt environment and migrate our 100+ VMs to it. :)

I can find no reason why this would be happening. AlmaLinux 9.4, oVirt 4.5.6, brand new/fresh cluster/install.
