yes, we support ceph via cinderlib, so in theory any vendor with a storage driver for cinder can work, but we only test ceph

All I need to do is select CinderLib option during Engine setup? in 4.3 you also need to enable: $ engine-config -s ManagedBlockDomainSupported=true Then I can add Managed Block Domains in the admin interface? after enabling, yes

Thank you very much! By the way, Is there some item list that show the changes between 4.3 and 4.4 ? -----Original Message----- From: users-bounces@ovirt.org <users-bounces@ovirt.org> On Behalf Of Benny Zlotnik Sent: Tuesday, September 14, 2021 8:08 PM To: Tommy Sway <sz_cuitao@163.com> Cc: users <users@ovirt.org> Subject: [ovirt-users] Re: what kind of managed block can oVirt manage ? Yes, but please be aware that 4.3 is EOL for a while, there have been significant changes between 4.3 and 4.4 in all relevant components On Tue, Sep 14, 2021 at 2:39 PM Tommy Sway <sz_cuitao@163.com> wrote:

As I understand it now, on 4.3 I need to enable it like this: 1. Activate the REPO source and install cinder relevant software 2, when run the engine-setup add -s ManagedBlockDomainSupported = true option 3. Add ManagedBlockDomain after installation Do I understand this correctly?

Thank you very much!

Do you mean that I don't need to manually add cider related repo in the new version, the engine-setup process will automatically add cinder related repo and install the package?

it will add the repo but will not install the package as we had to revert this for now
