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

How to re-enroll (or renew) host certificates for a single-host hosted-engine deployment?
by Derek Atkins
Hi,
I've got a single-host hosted-engine deployment that I originally
installed with 4.0 and have upgraded over the years to 4.3.10. I and some
of my users have upgraded remote-viewer and now I get an error when I try
to view the console of my VMs:
(remote-viewer:8252): Spice-WARNING **: 11:30:41.806:
../subprojects/spice-common/common/ssl_verify.c:477:openssl_verify: Error
in server certificate verification: CA signature digest algorithm too weak
(num=68:depth0:/O=<My Org Name>/CN=<Host's Name>)
I am 99.99% sure this is because the old certs use SHA1.
I reran engine-setup on the engine and it asked me if I wanted to renew
the PKI, and I answered yes. This replaced many[1] of the certificates in
/etc/pki/ovirt-engine/certs on the engine, but it did not update the
Host's certificate.
All the documentation I've seen says that to refresh this certificate I
need to put the host into maintenance mode and then re-enroll.. However I
cannot do that, because this is a single-host system so I cannot put the
host in local mode -- there is no place to migrate the VMs (let alone the
Engine VM).
So.... Is there a command-line way to re-enroll manually and update the
host certs? Or some other way to get all the leftover certs renewed?
Thanks,
-derek
[1] Not only did it not update the Host's cert, it did not update any of
the vmconsole-proxy certs, nor the certs in /etc/pki/ovirt-vmconsole/, and
obviously nothing in /etc/pki/ on the host itself.

4.5.4 with Ceph only storage
by Maurice Burrows
Hey ... A long story short ... I have an existing Red Hat Virt / Gluster hyperconverged solution that I am moving away from.
I have an existing Ceph cluster that I primarily use for OpenStack and a small requirement for S3 via RGW.
I'm planning to build a new oVirt 4.5.4 cluster on RHEL9 using Ceph for all storage requirements. I've read many online articles on oVirt and Ceph, and they all seem to use the Ceph iSCSI gateway, which is now in maintenance, so I'm not real keen to commit to iSCSI.
So my question is, IS there any reason I cannot use CephFS for both hosted-engine and as a data storage domain?
I'm currently running Ceph Pacific FWIW.

New host cannot connect to master domain
by ovirt＠kirschke.de
Hi,
i just installed a new host, which cannot connect to the master domain. The domain is an iscsi device on a nas, and ovirt is actually fine with it, other hosts have no problem. I'sure , I#m just overlooking something.
What I see in the log is:

The domain a15496dc-c241-4658-af9d-0dfe11783916 definitely exist, and works on other systems.
THe new host can acces the iscsi targets, and i am able to log into them.
Any one who knows, which blinder I have to remove, so I see the actual problem?
Thanks and best regards

How to access the ovirt node individually?
by De Lee
Hi,
I've installed the ovirt manager on top of the oVirt node. For some reason the node went to offline and unable to start the ovrit manager.
Do we have option to enable the auto start of the ovrit manager and can I able to connect the console of the ovirt node try to power on the VM?

VM Snapshot tab error Code 500
by doboscsongor＠gmail.com
Hi everybody,
I'm new to the oVirt environment, so I started with a fresh install on two physical servers using a hosted engine scenario. Currently, I have version 4.5.6-1.el8 installed. For storage, I am using FC to access our storage.
I have created a test VM for testing purposes where I installed MS Windows Server 2022. On the VM, I installed the guest tools, and everything is working fine except for the snapshots tab. If I don't have any snapshots for the VM, I can view the snapshots tab, but if I create a snapshot, the snapshots tab shows an error:
"Error while executing action: A request to the server failed with the following status code: 500."
Does anyone have any idea why I am getting this error?
Thanks in advance!
