Grazie Sandro!
I understand it has been a very hard release to do, but this is 
absolutely welcome!

Will try it asap on my testbed and give feedback.

Cheers,

Andrea

[ovirt-users] Re: Impossibile to install a new system

2023-09-19 Thread Andrea Chierici

Dear Sandro,
this gives me a clear idea of the status of the project unfortunately.
But please let me explain my use case and maybe you can suggest me the 
correct solution.
In my organization we have several ovirt installations, some with hosted 
engine, some with a separate VM running on "something else".
Personally I have 2 instances that I care most and they are still 
running 4.5.4.
You suggested several months ago that we should switch to nightlies, but 
since I need to be sure they work correctly, I want to test them on a 
separate tesbed. Hence I wanted to install a brand new mini cluster to 
test the nightlies before running them in production (I think this is 
the correct approach in general).
Anyway since nightlies change quite often and are not versioned, it's 
not simple, I think, to test them on a testbed and then bring them in 
production, since some packages may have already been updated.
So, what do yuo suggest me to do, to be sure I run in production only 
tested software?

THanks a lot for your support.

Andrea

Dear all,

I've tried both starting from a centos8 stream system and a

but the engine installation always breaks here:

TASK [ovirt.ovirt.hosted_engine_setup : Wait for the host to be up]

I keep getting the same problem, it looks like the engine is not
"migrated" to the public ip and is stuck on the natted address
that the
installation process is using during the preliminary phase.
Here is a message that seems to confirm my theory:

I am
simply wondering: is there a way to install ovirt 4.5.4 today or
is it
all already lost??!

[ovirt-users] Re: QXL vs VGA

2022-09-23 Thread Andrea Chierici

Hi,
I've done some investigation and discovered that the problem seems 
related to the engine ca not installed in my windows machine keychain.
Anyway even if I installed the cert, the classic console.vv file 
continue to complain with failed handshake; on the other hand, on the 
browser I can open novnc consoles, if I install the engine ca on it.
I can survive with novnc, but a recipe for remote-viewer + windows 
systems could be useful, I bet, not only for me.

Thanks,

Andrea

[ovirt-users] Re: Notified that Engine's certification is about to expire but no documentation to renew it

2022-08-10 Thread Andrea Chierici

Dear all,
I had a similar problem with engine certificate and solved it, reading 
this thread.
The strange thing is that now every time I log on the engine I get 
warnings about host certificates about to expire, even if the expiry 
date is in 2023. This looks weird to me and I wonder if there is 
somewhere a setting to specify how in advance the warning should be given.


Here is an example:



Any hint?
Thanks,

Andrea

Hi Guillaume,

to renew host certificates you need to perform following actions in 
webadmin or RESTAPI:


1. Move the host to Maintenance status
2. Execute Enroll Certificates for the host
3. Watch Events on the host to see if Enroll Certificates finished 
successfully

4. Execute Activate for the host

Martin

[ovirt-users] Console error

2022-05-11 Thread Andrea Chierici

Hi,
yesterday I've migrated from 4.4.10.7-1 to 4.5.0.7-1. Installation went 
fine and no error at all was reported.
A problem anyway is now hitting my installation: if I try to open a vm 
console, I get the error:


Failed to complete handshake Error in the pull function

It's not a problem on my browser/os since with another 4.4.x ovirt 
installation, consoles work flawlessly. No modifications at all were 
made to default settings on console.
Any suggestion on how to solve this issue? Haven't seen any previous 
report on this.


Thanks,

Andrea

[ovirt-users] Instability after update

2022-01-05 Thread Andrea Chierici

Cheers,
I am in trouble...
I am running an ovirt manager v4.4.9.5-1.el8. This week I updated all 
the hosts to latest release (starting from repo 
ovirt-release44-4.4.9.3-1.el8.noarch) since I hadn't done that when I 
upgraded the manager. Before that the system was rock solid. 
Unfortunately, after the upgrade, I get frequent errors on running VMs:


VM  is down with error. Exit message: Lost connection with qemu 
process.


I can't get any hint from the logs, I wonder if someone has any idea of 
what is going on.

Thanks,

Andrea

[ovirt-users] Slow mirrors, installation fails

2021-09-17 Thread Andrea Chierici

Dear all,
I am trying to install a new ovirt deployment with self hosted engine.
I've been trying since yesterday but it always fails.
On the deployment host I get this error:

[ ERROR ] Hosted Engine deployment failed: please check the logs for 
the issue, fix accordingly or re-deploy from scratch.
  Log file is located at 
/var/log/ovirt-hosted-engine-setup/ovirt-hosted-engine-setup-20210917144651-ecm06v.log


I connected to the console of the hosted engine and in dnf.log I found this:

Indeed the speed of the mirrors seems quite low and even on another

while for all other centos repos it is at least 10MB.

Am I missing something?

[ovirt-users] Re: Major network issue with 4.4.7

2021-08-10 Thread Andrea Chierici

Dear all,
thanks a lot for your support.
In the end, I was using the wrong bonding options when reinstalling centos8.
My centos7 hosts were installed years ago and in the meanwhile I 
installed other infrastructures with different bonding options... and I 
got confused.


Everything is solved.

Dear all,
I've been using ovirt for at least 6 years and only lately I've

My hardware is:

- dell equallogic for iscsi storage, directly connected to the blade

My engine is hosted on a separate vmware vm (I will evaluate the self 
hosted engine later...). I want to stress the fact that for years 
this setup worked smoothly without any significant issue (and all the 
minor updates were completed flawlessly).


A few weeks ago I started the update from the rock solid 4.3 to the 
latest 4.4.7. I began with the manager, following the docs, 
installing a new centos8 vm and importing the backup: everything went 
smootly and I was able to get access to the manager without any 
problem, all the machines still there :)
I then began updating the hosts, from centos7 to centos8 stream, one 
by one.
Immediately I noticed network issues, with the VMs hosted on the 
first updated host. Migrating VMs from centos8 host to other centos8 
quite often fails, but the main issue is this: *if I start one of the 
VMs on the centos8 host, they have no network connectivity. If I 
migrate them to a centos7 hosts the network starts to work, and if I 
migrate the VMs back to the centos8 host, the network keeps working.*
I am puzzled and can't understand what's going on. Generally speaking 
all the centos8 hosts (I have 6 in my cluster, and now 3 are centos8 
while the rest is still centos7) seem to be very unstable, meaning 
that the VMs they host are quite often showing network issues and 
temporary glitches.


Can someone give a hint on how to solve this weird issue?

[ovirt-users] Achieving high availability

2021-02-02 Thread Andrea Chierici

Hi,
I am trying to configure high availability on a critical VM. My ovirt 
version is 4.3.10.4-1.el7.
My question is about the best settings to specify, since it's not 
completely clear to me how they influence the availability.


What I want is simply to have a specific machine ALWAYS running, or at 
least, to be available as much as possible. I have no special 
requirements on the VM, if it goes down, simply restarting it is fine.


Here is my current setting. Is it good or I'd better chage anything?



Thanks,
Andrea

[ovirt-users] Re: Failing to restore a backup

2020-07-15 Thread Andrea Chierici

Dear all,
I think I finally understood the issue, even if I don't know how to fix it.

Trying to install a new HE from a backup I get the error:
 "The host has been set in non_operational status, please check engine 
logs, more info can be found in the engine logs, fix accordingly and 
re-deploy."


*The host, not the hosted engine*. This is more clear in another log:
Host  is set to Non-Operational, it is missing the 
following networks: 'iscsi_net,sgsi_iscsi,sgsi_priv,sgsi_vpn'


The fact is that those networks are present on the host:
# ip addr

26: sgsi_priv:  mtu 1500 qdisc noqueue 
state UP group default qlen 1000

    link/ether 90:e2:ba:63:2e:bc brd ff:ff:ff:ff:ff:ff
    inet6 fe80::92e2:baff:fe63:2ebc/64 scope link
28: sgsi_vpn:  mtu 1500 qdisc noqueue 
state UP group default qlen 1000

    link/ether 90:e2:ba:63:2e:bc brd ff:ff:ff:ff:ff:ff
    inet6 fe80::92e2:baff:fe63:2ebc/64 scope link
   valid_lft forever preferred_lft forever

The other two are configured on ovirt but not configurable on bare metal 
system, indeed if I issue "ip addr" on a production host I don't see 
those nets at all: I am puzzled. The problem is definitely this one, can 
anyone provide any suggestion on how to proceed?
Why is it complaining about sgsi_priv and sgsi_vpn that are not missing 
at all?

I think this is not a critical failure, and is not what failed the restore.




Recently I tried the 4.3.11 beta and 4.4.1 and the error now is different:

This is part of 'engine-setup' output, which 'hosted-engine' runs inside the 
engine VM. If you can access the engine VM, you can try finding more 
information in /var/log/ovirt-engine/setup/* there. Otherwise, the 
hosted-engine deploy script might have managed to get a copy to 
/var/log/ovirt-hosted-engine-setup/engine-logs*. Please check/share these. 
Thanks.


Unfortunately the installation procedures when exiting, deletes the vm, hence I 
can't log in.

Are you sure? Did you check with 'ps', searching qemu processes?

If it's still up, but still using a local IP address, you can find it
by searching the hosted-engine logs for 'local_vm_ip' and login there
from the host.


Here are the ERROR messages I got on the logs copied on the host:

engine.log:2020-07-08 15:05:04,178+02 ERROR

Can not run fence action on host '', no suitable proxy host 
was found.

That's ok.

This probably indicates a problem, but I agree it's not very helpful.


grep: setup: Is a directory

Right - so please search inside it.

Also please check the hosted-engine deploy logs themselves.


Not very helpful.





I simply can't figure out what file is missing.
If, as a test, I try to install the HE without restoring the backup, the 
installation goes smoothly to the end, but at that point I can't restore the 
backup, as far as I can understand.


Another option is to do the restore manually. To find relevant information, search the 
net for "enginevm_before_engine_setup".


Later I will give it a try.

Good luck and best regards,

[ovirt-users] Failing to restore a backup

2020-07-14 Thread Andrea Chierici

Dear all,
I'm rather new to the list, not to ovirt, that I use since 2014 profitably.
I've a problem with an ovirt instance and I am desperately seeking for help.

I run a 4.3 self hosted engine installation, with 8 hypervisors and an 
iscsi storage.
Since the storage is not  very reliable, I bought a dell powervault 
where to move everything. No problem to move the VMs, the problem came 
out with the hosted engine.
I've read many documentation and the procedure I think I must follow 
involves backing up the current HE, powering it off, installing a new 
host where to create a new HE recovering the backup.

The command I used to generate the backup is:
engine-backup --mode=backup --file=file_name --log=log_file_name

and the command used to restore it on the new HE is:
hosted-engine --deploy --restore-from-file=backup/file_name

The problem comes out during the recovering of the backup.

With versions prior to 4.3.11 and also with 4.4.0 I got the error:
2020-06-25 15:17:34,950+0200 ERROR ansible failed {

Any hint on what I may be missing?
