Local LVM on KVM hosts
Hello,
Is there a way to use the local LVMs as a primary storage on the KVM hosts?
Thanks!

Agreed, we still have a couple of clusters running CLVM and it's over complicated and can be unstable due to the nature of the required cluster locking. We're working to offload these currently. So stay away from CLVM if you can [😊]

+1 for Nux’ comment. CLVM is a challenge, and stability is an issue IMO.

LVM is not a supported primary storage for Cloudstack. CLVM is, however that's not the same thing - and it's not really "local".
I'd advise against using it, CLVM is not really a first class citizen in Cloudstack.
If you can use local storage with qcow2, that'd be ideal. Easy to deploy, template, snapshot etc etc.

Hello,
Thanks! I'm sorry, maybe I wasn't clear enough, but the thing I meant is using separate LVM volumes without QEMU-images. :)

There is also a PR currently in queue to enable live migration (including storage) between local storage backed hosts I believe.

Hi Vladimir,
Yes you can use local storage on KVM – you need to:
1) Enable it when you create the zone.
2) Create service offerings with local storage.
