Nested Virtualization, please, help-me
by Jorge Visentini
Hi folks.
So... I read the documentation in many sites and this forum too, buuut the
nested feature do not worked yet.
*My host oVirt so far:*
cat /sys/module/kvm_intel/parameters/nested
1
Kernel parameters edited by Engine on *Edit Host -> Kernel*.
Reinstall the host and reboot.
*cat /proc/cmdline*
BOOT_IMAGE=(hd0,msdos1)//ovirt-node-ng-4.4.10.2-0.20220303.0+1/vmlinuz-4.18.0-365.el8.x86_64
crashkernel=auto resume=/dev/mapper/onn-swap
rd.lvm.lv=onn/ovirt-node-ng-4.4.10.2-0.20220303.0+1
rd.lvm.lv=onn/swap rhgb quiet
root=/dev/onn/ovirt-node-ng-4.4.10.2-0.20220303.0+1
boot=UUID=07e688ed-8d46-4932-b070-378c75ba1921 rootflags=discard
img.bootid=ovirt-node-ng-4.4.10.2-0.20220303.0+1 kvm-intel.nested=1
*On VM guest:*
Host set to "Specific Host" and "Pass-Through Host CPU"
vmx is ok
*root@kceve01:~# kvm-ok*
INFO: /dev/kvm exists
KVM acceleration can be used
*Result:*
I am trying to virtualize the EVE-NG. I can start the guest of the EVE-NG,
but I don't know why I can't access it. It's like blocking any package...
I don't know yet if it is a virtualization problem or network problem...
If you have other tips for me, I glad, very glad.
All the best!

struggling with 4.5.1 install
by Chris Smith
Hello,
Here's the general gist of what I've done so far:
graphical install from el8 and el9 iso, using as few modifications as
possible with dhcp networking.
3.6TB of disk space for ovirt install dest.
system comes up, dashboard is online, i try to deploy hosted engine, no
dice.
[image: image.png]
it's similar to this:
https://bugzilla.redhat.com/show_bug.cgi?id=1946095
ok, so i go for cli install
i manually install ovirt-engine-appliance and that seems to go ok
i kick off ovirt-hosted-engine-setup and follow the prompts
i watch the logs and such and seems to be ok
i have to make entry in /etc/hosts to have new hostname for not yet built
hosted engine VM to resolve to IP address ( I don't have "real" DNS at the
moment)
that succeeds but then new engine VM is spun up in new IP subnet
192.168.222.0/24 that is different from primary 192.168.1.0/24 not sure why.
i am at a point where i can't get a GUI to the hosted engine IP because
it's only available to the internal adapter on the node.
i feel like the installers in the el8 and el9 iso's is just completely
b0rked.
what am I doing wrong?
oh, and where is everyone at in the IRC chat room?
thanks,
Chris

No "Virtualization" tab on Node cockpit
by giuliano.david＠nvgroup.it
Hi. I'm new to oVirt.
Trying to install the first node with hosted engine on it.
The node bare install process from the iso image (ovirt-node-ng-installer-4.5.1-2022062306.el9.iso) is fine on a Fujitsu server.
Accessing via browser the node cockpit at port 9090, on the left panel the entry "Virtualization" is missing (installing Node version 4.4.6 it was present and working), so I can't launch the hosted engine setup via UI.
Trying to deploy via command line ( $ hosted-engine --deploy ), the installation process stops with the error:
[ ERROR ] {'changed': True, 'stdout': '', 'stderr': '', 'rc': 1, 'cmd': "[ -r /etc/sysconfig/libvirtd ] && sed -i '/## beginning of configuration section by vdsm-4.[0-9]\\+.[0-9]\\+/,/## end of configuration section by vdsm-4.[0-9]\\+.[0-9]\\+/d' /etc/sysconfig/libvirtd", 'start': '2022-08-04 18:24:31.817314', 'end': '2022-08-04 18:24:31.819845', 'delta': '0:00:00.002531', 'failed': True, 'msg': 'non-zero return code', 'invocation': {'module_args': {'warn': False, '_raw_params': "[ -r /etc/sysconfig/libvirtd ] && sed -i '/## beginning of configuration section by vdsm-4.[0-9]\\+.[0-9]\\+/,/## end of configuration section by vdsm-4.[0-9]\\+.[0-9]\\+/d' /etc/sysconfig/libvirtd", '_uses_shell': True, 'stdin_add_newline': True, 'strip_empty_ends': True, 'argv': None, 'chdir': None, 'executable': None, 'creates': None, 'removes': None, 'stdin': None}}, 'stdout_lines': [], 'stderr_lines': [], '_ansible_no_log': False, 'item': '/etc/sysconfig/libvirtd', 'ansible_loop_var': 'item', '_ansible_
item_label': '/etc/sysconfig/libvirtd'}
I can't really understand what's going on ...
Can anyone please point me in the right direction to fix that? Is it a bug?
Thanks!!!

Hi,
I was wondering If I have HA- setup of manager + 2 hosts. If manager crashes, does 2 host crash also or do they still continue working normally?

Failover IP on Hetzner
by Tommaso - Shellrent
Hi to all.
we want to configure a failover ip on an Hetzner host. Anyone can be
able of make it works?
Ip failover does not include a MAC address, so it cant't work on a
bridged network. They sauggest su confure it on a routed network.
On ovirt, how can we make it work?
Regards,
Tommaso.

Certificates Expiration Problem - Urgent Help Needed
by Andrei Verovski
Hi !
Today my hosts (engine + all nodes) certificates expired and I re-run
engine-setup to renew certificates.
Then I did for each node host:
Edit host -> Advanced parameters -> Fetch SSH public key (PEM)
in order to update certificates on nodes, everything was finished just fine.
Unfortunately, one of the most crucial nodes (node14) still shows this
error:
VDSM node14 command Get Host Capabilities failed: PKIX path validation
failed: java.security.cert.CertPathValidatorException: validity check failed
Restarted vdsms and vdsm-network, still same, node is marked as
non-responsive, and all VM with "?" sign (unknown status).
However, node14 pings without any problem, its storage domain shown in
green (OK), and all VMs are running fine.
Service vdsm-network status is OK, vdsmd is NOT:
Aug 08 22:07:27 node14.***.lv vdsm[1264164]: ERROR ssl handshake: socket
error, address: ::ffff:192.168.0.4
This node is running our accounting and stock control system, its
storage domain holds VM disk of that software. If its nonoperational
after restart, its a BIG trouble, I will not be able to migrate VM disk
anywhere. Restoring accounting DB from daily backup is a lengthy process
for 2 - 3 hours.
Please advice what to do next.
Thanks in advance.

Q: How to fix ghost "locked" status of VM
by Andrei Verovski
Hi,
Creating snapshot of one of the VM vailed, and zombie tasks was killed with:
su postgres
psql -d engine -U postgres
select * from job order by start_time desc;
select DeleteJob('UUID_FROZEN_TASK_ID’);
However, VM remains in locked state (with lock sign left-below red “DOWN” arrow in status column of web interface.
I run:
/usr/share/ovirt-engine/setup/dbutils/unlock_entity.sh -t all
then rebooted engine VM, still no luck. Can’t do anything with that VM.
Please advise how to fix.
Thanks in advance.
