Using Managed Block Storage (cinderlib) with a driver that supports NVMe/TCP. Lastest oVirt has the needed changes to configure this. Benny and I tested with Lightbits[1] driver in a virtualized environment. This is basically a POC that may work for you or not, or require more work that you will have to do yourself since not much development is happening now in oVirt. 2. Using the devices via multipath Legacy storage domains are based on multipath. It may be possible to use multipath on top of NVMe devices, and in this case they look like a normal LUN so you can create a storage domain from such devices. oVirt will not handle connections for you, and all the devices must be connected to all nodes at the same time, just like FC/iSCSI LUNs. You will likely not get the performance benefit of NVMe/TCP. 3. Using host devices If what you need is using some devices (which happen to be connected via be NVMe/TCP), maybe you can attach them to a VM directly (using host devices). This gives the best possible performance but no features (snapshots, backup, live migration, live storage migration, etc.) [1] https://www.lightbitslabs.com/ Nir

I know they have been deprecated and can be replaced with Data, but we still use the ISO and Export domain types and like having them. Cheers! ... Wild

Couldn't set you as assignee here as well.

In this one I was able to set you as an assignee. The only difference I see compared to the other issues is that in this one there was one comment from you.

Looks like I'm not allowed to set you as assignee there, but I closed it mentioning you and your PR there. If I figure out how to set you as an assignee there, I'll be more than happy to do that.
