[Call to Action] oVirt 4.5 localization updated in zanata
by Sandro Bonazzola
Hi, https://zanata.ovirt.org/ has been updated with new text to be translated.
If you want to help with this, please follow
https://ovirt.org/develop/localization.html
The ovirt-web-ui and ovirt-engine-ui-extensions projects lack Italian,
Czech and Turkish translation.
The oVirt engine project needs some touch on all the translations but
especially on Italian, Czech, Russian and Turkish
Thanks,

Migrate Hosted-Engine from one NFS mount to another NFS mount
by Brian Ismay
Hello,
I am currently running Ovirt 4.2.5.3-1.el7 with an Hosted-Engine running on
nfs-based storage.
I am needing to migrate the backend NFS store for the Hosted-Engine to a
new share.
Is there specific documentation for this procedure? I see multiple
references to a general procedure involving backing-up the existing install
and then re-installing and restoring the backup. Is there any way to make a
more clean change of the configuration?
Thanks,
Brian Ismay

Re: VMs losing network interfaces
by Strahil Nikolov
That's a good start.
Are you building your VMs from template ?Any chance there is another system (outside oVirt ?) with the same MAC ?
you can run arping and check if you get response from more than 1 system.

</interface>
lspci on the VM show also the interface and I can also bring the interface up again with: ifup enp1s0. So it only loose the connection, not the interface.
When I restart the VM I get this log message:
/var/log/syslog:Feb 21 10:11:29 tv-planer sh[391]: ifup: failed to bring up enp1s0
/var/log/syslog:Feb 21 10:11:29 tv-planer systemd[1]: ifup(a)enp1s0.service: Main process exited, code=exited, status=1/FAILURE
/var/log/syslog:Feb 21 10:11:29 tv-planer systemd[1]: ifup(a)enp1s0.service: Failed with result 'exit-code'.
But the VM got his IP and is reachable.

Do you see all nic in the UI ? What type are they ?
Set this alias on the Hypervisors: alias virsh='virsh -c qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf' and then use 'virsh dumpxml name-of-vm' to identify how many nics the vm has .
If gou got the correct settings in ovirt, use 'lspci -vvvvv' .

I have here a strange behavior: We have a 3 node self hosted cluster
with around 20 VMs running on it. Since longer I had the problem with
one VM that after some days it lose the network interface. But because
this VM was only for testing I was to lazy to dive more in, to figure
out what is happen.
Now I have a second VM, with the same problem and this VM is more
important. Both VMs running debian 10 and use cifs mounts, so maybe that
is related?
Have some one of you seeing this behavior? And can give me a hint, how I
can fix this?
At the moment I can't provide a log file, because I didn't know the
exact time, when this was happen. And I also don't know, if the problem
comes from ovirt or from the operating system inside the VMs.
Have a nice day!

hosted engine deployment (v4.4.10) - TASK Check engine VM health - fatal FAILED
by Charles Stellen
Dear Ovirt Hackers,
sorry: incidently send to devel(a)ovitr.org
we are dealing with hosted engine deployment issue on a fresh AMD EPYC
servers:
and we are ready to donate hardware to Ovirt community after we pass
this issue ( :-) )
0/ base infra:
- 3 identical physical servers (produced in 2021-4Q)
- fresh, clean and recent version of centos 8 stream installed
(@^minimal-environment)
- servers are interconnected with cisco switch, each other are network
visible,
all with nice internet access (NAT)
1/ storage:
- all 3 servers/nodes host nice and clean glusterfs (v9.5) and volume
"vol-images01" is ready for VM images
- ovirt hosted engine deployment procedure:
- easily accept mentioned glusterfs storage domain
- mount it during "hosted-engine --deploy" with no issue
- all permissions are set correctly at all glustrfs nodes ("chown
vdsm.kvm vol-images01")
- no issue with storage domain at all
2/ ovirt - hosted engine deployment:
- all 3 servers successfully deployed recent ovirt version with standart
procedure
(on top of minimal install of centos 8 stream):
dnf -y install ovirt-host
virt-host-validate: PASS ALL
- at first server we continue with:
dnf -y install ovirt-engine-appliance
hosted-engine --deploy (pure commandline - so no cockpit is used)
DEPLOYMENT ISSUE:
- during "hosted-engine --deploy" procedure - hosted engine becomes
temporairly accessible at:https://server01:6900/ovirt-engine/
- with request to manualy set "ovirtmgmt" virtual nic
- Hosts > server01 > Network Interfaces > [SETUP HOST NETWORKS]
"ovirtmgmt" dropped to eno1 - [OK]
- than All pass fine - and host "server01" becomes Active
- back to commandline to Continue with deployment "Pause execution until
/tmp/ansible.jksf4_n2_he_setup_lock is removed"
by removing the lock file
- deployment than pass all steps_until_ "[ INFO ] TASK
[ovirt.ovirt.hosted_engine_setup : Check engine VM health]"
ISSUE DETAILS: new VM becomes not accessible in the final stage - as it
should be reachable at its final IP:
[ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Fail if Engine IP is
different from engine's he_fqdn resolved IP]
[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg":
"Engine VM IP address is while the engine's he_fqdn
ovirt-engine.mgmt.pss.local resolves to 10.210.1.101. If you are using
DHCP, check your DHCP reservation configuration"}
- problem is, that even if we go with "Static" IP (provided during
answering procedure) or with "DHCP" way (with properly set DHCP and DNS
server responding with correct IP for both
WE STUCK THERE
WE TRYIED:
- no success to connect to terminal/vnc of running VM "HostedEngine" to
figure out the internal network issue
any suggestion howto "connect" into newly deployed UP and RUNNING
HostedEngine VM? to figure out eventually manualy fix the internal
network issue?
Thank You all for your help
Charles Stellen
PS: we are advanced in Ovirt deployment (from version 4.0), also we are
advanced in GNU/Linux KVM based virtualisation for 10+ years,
so any suggests or any details requested - WE ARE READY to provide
online debuging or direct access to servers is not a problem
PPS: after we pass this deployment - and after decomissioning procedure
- we are ready to provide older HW to Ovirt community

help using nvme/tcp storage with cinderlib and Managed Block Storage
by muli＠lightbitslabs.com
Hi everyone,
We are trying to set up ovirt (4.3.10 at the moment, customer preference) to use Lightbits (https://www.lightbitslabs.com) storage via our openstack cinder driver with cinderlib. The cinderlib and cinder driver bits are working fine but when ovirt tries to attach the device to a VM we get the following error:
libvirt: error : cannot create file '/var/run/libvirt/qemu/18-mulivm1.dev/mapper/': Is a directory
We get the same error regardless of whether I try to run the VM or try to attach the device while it is running. The error appears to come from vdsm which passes /dev/mapper as the prefered device?
2022-02-22 09:50:11,848-0500 INFO (vm/3ae7dcf4) [vdsm.api] FINISH appropriateDevice return={'path': '/dev/mapper/', 'truesize': '53687091200', 'apparentsize': '53687091200'} from=internal, task_id=77f40c4e-733d-4d82-b418-aaeb6b912d39 (api:54)
2022-02-22 09:50:11,849-0500 INFO (vm/3ae7dcf4) [vds] prepared volume path: /dev/mapper/ (clientIF:510)
Suggestions for how to debug this further? Is this a known issue? Did anyone get nvme/tcp storage working with ovirt and/or vdsm?
Thanks,
Muli

Migrating VMs from 4.3 Ovirt Env to new 4.4 Env
by Abe E
So as title states I am moving VMs from an old system of ours with alot of issues to a new 4.4 HC Gluster envr although it seems I am running into what I have learnt is a 4.3 bug of some sort with exporting OVAs.
Some of my OVAs are showing large GB sizes although their actual size may be 20K so they are showing no boot device as well, theres really no data there. Some OVAs are fine but some are broken. So I was wondering if anyone has dealt with this and whats the best way around this issue?
I have no access remotely at the moment but when I get to them, I read somewhere its better to just detach disks and download them to a HDD for example and build new VMs and upload those disks and attach them instead this way?
Please do share if you have any better ways, usually I just Export OVA to an external HDD, remount to new ovirt and import OVA but seems a few of these VMs out of alot did not succeed and I am running out of downtime window.
Thanks a bunch, I have noticed repeated names helping me, I am very grateful for your help.

Re: oVirt alternatives
by Thomas Hoberg
That's exactly the direction I originally understood oVirt would go, with the ability to run VMs and container side-by-side on the bare metal or nested with containers inside VMs for stronger resource or security isolation and network virtualization. To me it sounded especially attractive with an HCI underpinning so you could deploy it also in the field with small 3 node clusters.
But combining all those features evidently comes at too high a cost for all the integration and the customer base is either too small or too poor: the cloud players are all out on making sure you no longer run any hardware and then it's really just about pushing your applications there as cloud native or "IaaS" compatible as needed.
E.g. I don't see PCI pass-through coming to kubevirt to enable GPU use, because it ties the machine to a specific host and goes against the grain of K8 as I understand it.
Memory overcommit is quite funny, really, because it's the same issue as the original virtual memory: essentially you lie to your consumer about the resources available and then swap pages forth and back in an attempt to make all your consumers happy. It was processes for virtual memory, it's VMs now for the hypervisor and in both cases it's about the consumer and the provider not continously negotiating for the resources they need and the price they are willing to pay.
That negotiation is always better at the highest level of abstraction, the application itself, which why implementing it at the lower levels (e.g. VMs) becomes less useful and needed.
And then there is technology like CXL which essentially turns RAM in to a fabric and your local CPU will just get RAM from another piece of hardware when your application needs more RAM and is willing to pay the premium something will charge for it.
With that type of hardware much of what hypervisors used to do goes into DPUs/IPUs and CPUs are just running applications making hypercalls. The kernel is just there to bootstrap.
Not sure we'll see that type of hardware at home or in the edge, though...

Gluster Performance issues
by Alex Morrison
Hello All,
We have 3 servers with a raid 50 array each, we are having extreme
performance issues with our gluster, writes on gluster seem to take at
least 3 times longer than on the raid directly. Can this be improved? I've
read through several other performance issues threads but have been unable
to make any improvements

Unable to update self hosted Engine due to missing mirrors
by jonas＠fleckmail.de
Hi together,
I already checked the other Threads here :) I know that there was an issue with old CentOS 8 repos.
Currently Im trying so update our self hosted engine as always but I get the following error:
Failed to download metadata for repo 'ovirt-4.4-centos-gluster8': Cannot prepare internal mirrorlist: No URLs in mirrorlist
Is there any "official" advise what I have to change in my repo lists? I don't want to break something.
Thank you very much :)
