[ovirt-users] Import FC Storage as iSCSI

Tue Nov 4 07:57:46 UTC 2014

Hi.

I have managed to get my oVirt node running using oVirt Node Hypervisor 3.1.0_master-20140707.0. I hope this is not causing following issue, but this Is the only way for me to test 3.5.

When I try to import existing FC storage domain I get errors on Engine (see attached log).

Regards.

Raul
