FYI: I recently found that ceph performs quite well in vmware, when using the VM as a "direct" ceph client. (Our tests involved directly mounting an RBD device from the VM)
So as long as you can treat the OS level as throwaway, and use ceph-to-the-vm for your actually important data, this might be also a good thing to use in ovirt. ----- Original Message ----- From: "Eyal Shenitzky" <eshen...@redhat.com> To: "Sandro Bonazzola" <sbona...@redhat.com>, "Benny Zlotnik" <bzlot...@redhat.com>, matt...@peregrineit.net Cc: "users" <users@ovirt.org> Sent: Wednesday, April 21, 2021 12:30:39 AM Subject: [ovirt-users] Re: n00b Requesting Some Advice Hi Matthew, Currently, in order to use Ceph in oVirt you have 2 options: 1. Ceph using ISCSI gateway - regular ISCSI storage domain with Ceph as the storage backend, supports all the regular operations [1]. 2. Using the new Managed Block Storage (Cinderlib integration) technical-preview - Create a Managed Block Storage domain that doesn't support all the operations that we have for the "regular" storage domain you can find more info here [2] and [3]. Each option has its benefits.

We have a Ceph Storage Cluster (Octopus moving to Pacific) which we'd like to use with our new oVirt Cluster (all on CentOS 8 boxes). What I'd like to know is what is the "best" (ie recommended / best practice) way of doing this - via iSCSI, CFS, 'raw' RBD blocks, some other way I haven't read about yet, etc? I realise 'best' is a subjective term, but what I tend to do is do 'manual' installs so that I both actually understand what is happening (ie how things fit together - I pull apart and rebuild mechanical clocks and watches for the same reason) and also so I can '"Puppet-ise" the results for future use. This means that I am *not* necessarily looking for "quick and dirty" or "quick and easy" (ie, I have no trouble using the CLI and 'vim-ing' conf files as required) but I do want a solid, "best-practice" system when I'm done. So, can some please help? And also, would you mind pointing me towards the relevant documentation for the answer(s) supplied (yes, I *always* RTFM :-) ).
