you don't need to remove, ovirt should exclude "unsnappable" disks automatically, and direct LUN disks are "unsnappable". Regardless of this, you can choose yourself which disks you include in a snapshot

We know that now oVirt doesn't make snapshot for direct lun. 

Please consider this scenario:
I have a VM with total 2 disks: the os image disk is created on the nfs domain, while the other one is a direct lun disk.
Now I'd like to create a snapshot,

1. should I remove the direct lun disk first, then make a snapshot?
2. If I don't remove the direct lun disk, oVirt will exclude it automatically, and snapshot can also be created successfully. But I have no idea if this is supported by oVirt, please anyone can make some comments?

Thanks much.
