Hello Peter, Thank you for your answer. The problem is that i would like to use the feature in a production environment and can not rely on out of tree patches. In regard to my question i conclude the following: - There is currently no support for iSER storage objects in libvirt. - There will not be support for iSER storage objects in the next few libvirt releases. Which for me, at least at the moment, means dropping iSER/IB, using iSCSI/TCP/IPoIB and loosing some performance or using a commercially available hypervisor.

Other hardware is either running in production environment or reserved for emergencies. I mean it is kind of tricky to implement, since iSER sits somewhat between the iSCSI protocol and different transport methods. Maybe implementing it as its own protocol capable of communicating over different transport methods (RoCE, Infiniband, etc. (NOT: RDMA)) is the way to go. I think the author simply tried to adapt it to the implementation in qemu as best as he could to avoid self inflicting head wounds with his keyboard during alteration of the libvirt qemu driver.
