Hi! Please, anybody can write normal guide how to use ceph with Opennebula? Because in all manuals ceph use only for image store! I don’t need image store, I need store for VMs!
Thanks!
Hi @UAnton ,
VMs use the same ceph storage.
When you create a vm, opennebula makes a copy of your image in ceph(if you use ceph storage), and uses that storage for the vm.
Hi @thomasalrin,
How VM use same ceph storage if storage have TYPE = IMAGE?

Hi @UAnton,
I hope you configured the cephds datastore correctly, and cephds showing the size of your ceph storage.
Your image should be uploaded to cephds datastore.
Refer the images, we have working setup.
You may follow the below guide and see if thats help you.

Thanks, but this manuals is not complete and very lightweight. I add ceph storage like in all manuals but VM cant’t start on it!!! (see screenshots).
Can you send us onedatastore show -x 105, onedatastore show -x 0 and onevm show -x 6??
