Hello.which environment type I choose?
by 欧文
Dear:
Hello. My name is Owen. First, I appreciate you spend time to check my
email. Recently I want to use oVirt to build a project. But after reading
the official document, I have some questions to ask. The project is
intended to set up a physical server that is used to implement
virtualization, Variable quantity of thin clients for users. But I don't
know which environment types I should use to deploy. The number two
question is why the system environment is different between each version of
o-virt？Because centos 7 is the major version. But so many versions of
o-virt is not centos 7 or centos 8.can you tell me the reason. Thank you.At
last, I have a question.I ever joined the IRC, but there is no response to
answer my question. Could you tell me where I can take part in the
community with developers who develope o-virt.Thanks

multipath and VDSM REVISION value mappings
by Gianluca Cecchi
Hello,
considering that the best practice is to keep the multipath.conf file
unmodified, is there a table with the mapping between the version of
oVirt/RHV and the value of "VDSM REVISION" in /etc/multipath.conf, so that
in case of doubts one can crosscheck (eg inherited environment where
different admins were managing...)?
Does this value depend only on the hypervisor installed sw version or also
on the Cluster Compatibility version of the cluster the host belongs to, or
on the engine version?
In several oVirt/RHV environments with 4.3 / 4.4 I see several numbers for
the VDSM REVISION from 2.0, to 1.9 and 1.5...
Also what could be the impact of having a wrong (higher or lower) revision
inside the file?
Thanks,
Gianluca

oVirt + Proxmox Backup Server
by Diggy Mc
Is anyone using Proxmox Backup Server to backup VMs in an oVirt environment? Is it even possible?
I'm looking for a free open-source solution for my backup needs (backup VMs as well as traditional file backups). Any guidance is appreciated.

move ovirt 4.3.9 to RHEL 8
by Paul Dyer
Hi,
I am laying the groupwork for upgrade ovirt to 4.4. Since the standalone
ovirt mgr is now running on RHEL 7, I have installed RHEL 8 to a new VM.
Unfortunately, after installing ovirt-release43, I am not able to find
documentation for the dnf modules required. All the current documentation
point to ovirt-release44 and dnf modules not available for ovirt 4.3/RHEL 8.
I have these repos enabled...
Repo ID: ansible-2-for-rhel-8-x86_64-rpms
Repo ID: rhel-8-for-x86_64-appstream-rpms
Repo ID: rhel-8-for-x86_64-baseos-rpms
I am looking setup docs for a standalone engine of ovirt 4.3 on RHEL 8.
Thanks!
