After searching the official documentation, wiki and the code on gitlab, i still can not find any useful information about how to handle iSER targets with libvirt. I did find some RFCs for patches on this mailing list, but it seems none of them have been merged. There is also a somewhat related issue open on gitlab (https://gitlab.com/libvirt/libvirt/-/issues/16).
So effectively my question is the following: Is libvirt currently capable of supporting iSER targets as either storage pools or as virtio device and if not, is an implementation of such support planned?
The following patchset attempts to implement iser transport for disk source specification: https://www.redhat.com/archives/libvir-list/2020-April/msg01247.html It's fairly recent so you can give it a try and ideally provide a 'Tested-by:'. I don't have a RDMA setup handy so I can't test it and thus can provide a code-only review. In case of iSCSI storage pools I don't think that anybody is working on iser support.
