you shouldn't need this link, cinderlib is enabled by default in 4.5

Repos enabled by default in oVirt 4.5 should already set up the right
configuration for getting Ceph Pacific and RDO Yoga Cinderlib.
It would be interesting for a 4.6 release a rebase on Quincy/Zed if someone
wants to take the challenge.

[ovirt-users] Setting up hyperconverged engine with gluster storage

[Andy Michielsen]

Hello,

I'm setting up a new oVirt environment version 4.5 and want to use the
hyperconverged setup on gluster storage.

When I configure all the parameters and start the installation it keeps on
failing and I don't know why

TASK [gluster.infra/roles/backend_setup : Group devices by volume group
name, including existing devices] ***
fatal: [server1.test.local]: FAILED! => {"msg": "The task includes an
option with an undefined variable. The error was: 'str object' has no
attribute 'vgname'\n\nThe error appears to be in

line 3, column 3, but may\nbe elsewhere in the file depending on the exact

That blog was focused on Hosted Engine setup where one wanted to leverage a
pre-existing Ceph installation for storage (both for the dedicated storage
domain to assign to the hosted engine VM and for other storage domains to
be used for "regular" VMs).
Cinderlib was not supported for the initial hosted engine setup (where you
create the hosted engine dedicated storage domain) and the blog describes
how to overcome the limitation and configure your existing Ceph cluster
iSCSI gateway functionality, so that you make the initial install of oVirt
specifying iSCSi storage type
Then the blog describes how to use cinderlib for new storage domains after
install, to be used for "regular" VMs.

I don't know if there is a copy of the old 4.4 ones anywhere
you have to use this one (command line based):
https://ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engine_using_the_command_line/index.html
and there the section 3.2 Preparing iSCSI Storage
https://ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engine_using_the_command_line/index.html#Preparing_iSCSI_Storage_SHE_cli_deploy
is managed by you using the blog info above for iSCSI Gateway, and
eventually further modifications due to possible new releases of Ceph...

I can't find any instructions about cinder/ceph in ovirt docs.

This is because it is not supported, neither in RHV nor in oVirt. I don't
know where you can find the cinderlib part for oVirt now.
But you can refer to this Red Hat solution
https://access.redhat.com/solutions/5605141
(possibly you need a subscription, perhaps the free developer one is
sufficient)
You have to adapt the repos part for oVirt/CentOS Stream, though

Sandro, any added information here for oVirt repos to configure cinderlib
on oVirt 4.5?

[ovirt-users] Ovirt cinderlib integration docs

[fsayd]

Hello:

I am following Sandro's blog post to configure oVirt with Ceph as 
storage domain 
(https://blogs.ovirt.org/2021/07/using-ceph-only-storage-for-ovirt-datacenter/).


I need to setup cinderlib but the referenced link is dead: 
https://ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engine_using_the_cockpit_web_interface/index.html#Set_up_Cinderlib


I can't find any instructions about cinder/ceph in ovirt docs.

Any help?

Thanks
