am really enjoying oVirt but have now hit an issue with iSCSI. As there is only one NIC in the host I have had to enable an MTU of 9000 on ovirtmgmt. Then have vNIC profiles on that interface which are using a custom hook for Openvswitch. I have created a specific vLAN for iSCSI traffic and on the initiator and targets have set their respective interface MTUs to be 9000. When I connect to a LUN it is timing out straight away with a 1011 error. If I drop the MTU back to 1500 all works okay. This is all fine on my other KVM, non-oVirt, system so am wondering if I have missed a step ?
There is a closed bug regarding differen MTU sizes maybe it applies here as well? https://bugzilla.redhat.com/show_bug.cgi?id=1071660 it was closed because of insufficient data HTH -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.
