Hi, I'm writing cause I working on hosted-engine deploy over fiber channel. If possible, I'd like to try it for developing purposes in a nested environment. So I thought it would be possible to simulate a SAN with LIO and a vn2vn FCoE connection using a couple of VirtIO devices. I had some troubles using fcoeadm over VirtIO but than I found your patch about libhbalinux and libudev. I applied it and it works or at least it seams to. Here I tracked what I did: http://www.ovirt.org/Features/Self_Hosted_Engine_FC_Support Now the problem is that VDSM sees the FCoE device but it reports as failed: 'pathstatus': [{'lun': '0', 'physdev': 'sda', 'state': 'failed', 'type': 'FCP'}], and I'm not sure if it's really an issue with VDSM or if it's something with my FCoE setup. Did someone ever used VDSM with FCoE? thanks, Simone
