Hello @tmnguyen
About the XOSTOR limit, I read the devs saying it is like this as of now.
About using Linstor created by and for XOSTOR with another apps, in your case a Talos Kubernetes cluster, I think it should work, but all the volumes not created by XOSTOR would be unmanaged neither by XOSTOR nor by XO. So imagine, one admin would check in XO that a XOSTOR SR is not used anymore in the XO web ui, and would remove it. But would not think that it was also used for PV/PVC Kubernetes. There is this kind of risk. And as of now we do not support this.
By the way, we are going to start this month to write a CSI driver for Kubernetes for Xen Orchestra. This means from within a Kubernetes cluster you will create PVs/PVCs that would be backed by VM disks, aka VDIs
