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
