Hi,

In oVirt 4.3 it looks like the storage domains has been consolidated to data only and ISO, export are being deprecated, which IMHO is a good thing. However, when it comes to local storage and storage domains (when trying to mount local directory etc..) - the behavior of oVirt, IMHO, is weird, compared to other virtualization - your VM's are being switched to another domain, instead of just leaving them in the same domain and disabling live migration.

So, as I mentioned above, I don't see any reason for this switching if using local storage, but now there's a new technology on the block - the Optane DC, and Samsung will probably show their NVDiMM solution soon.

In both cases - in order to use this persistent memory, you'll need to "cut" part of the NVDiMM and mount it on the VM along side with your other NFS/iSCSI disks. This could probably kill live migration (at least in the first stage - see AMD MxGPU in the KVM forum video's work from AMD and Alibaba with live migration) - but that's a pretty good solution to utilize Optane DC/NVDiMM.

So my question is: Is there any chance that oVirt 4.4 will finally allow local storage to be just like NFS/iSCSI instead of kicking the node to another domain?

Also, will there be a functionality through the web interface to copy/move files between storage domains? I don't see it anywhere.

(In case you guys in Israel need some Optane DC's sticks, I can talk to Intel Israel about it)

Thanks
