Hi everyone, This my first post on this list Context : Some days ago I have decided to use infiniband for ISCSI streams. Infiniband adds a new wonderful transport protocol : ISER. This protocols is added to the well known the default TCP. (NB: ISER = ISCSI + RDMA). I could not see any ISCSI transport protocol modification support in libivirt (the default protocol tcp is even hardcoded in the regex) What i have done : - did the shell testing for the iscsiadm - the attached patch that corrects 2 typos in the original code and switches completely the iscsi transport protocol from tcp to iser (which is not ideal at all) What should be done (imho): - add iscsi transport protocol support (using my patch as a basis) - add a new XML property/whatever_fits_the_projects_policy to the storagepool object that allows user to pick the iscsi transport protocol (default is tcp) I was thinking of having something like : <pool type="iscsi"> <name>volumename</name> <source> <host name="1.2.3.4"/> <device path="IQNOFTARGET"/> <transport protocol="iser"/> </source> <target> <path>/dev/disk/by-path</path> </target> </pool> Any comment on this ? Any help on the XML part ? Best regards, Aurélien NB: the current iscsi transport protocols available are : tcp(default), iser, qla4xxx, bnx2, and icxgb3i. PS: i'm still doing extensive testing of my patch !DSPAM:4c46f49d90977882820711!
