If you issue the mount command does the path show.

mount |grep <path to vfd>

It looks like the ISO domain is on a NAS, so I would try a mount of the actual folder on the ovirt node to make sure you are able to access it. Also, can you place it in an export domain instead and try?

I think version 4.2+ it just needs to be in an export domain.

Also make sure the NAS path is correct. Most NAS use a data or shares for nfs mounts. (nasname:/shares/<file shares>

Subject: [ovirt-users] NFS permissions error on ISODomain file with correct permissions

Hi,

I asked this question in another thread but it seems to have been lost in the noise so I'm reposting with a more descriptive subject.

I'm trying to start a Windows VM and use the virtio-win VFD floppy to get the drivers but the VM startup fails due to a permissions issue detailed below.  The permissions look fine to me so why can't the VFD be read?

I found a permissions issue in the engine.log:

2020-03-25 21:28:41,662Z ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (ForkJoinPool-1-worker-14) [] EVENT_ID: VM_DOWN_ERROR(119), VM win-2019 is down with error.

But when I look at that path on the node in question, every folder and the final file have the correct vdsm:kvm permissions:

[root@ovirt-node-01 ~]# ll /rhev/data-center/mnt/nas-01.phoelex.com:_volume2_isostore/41cebb4b-c164-4956-8f44-6426170cd9f5/images/11111111-1111-1111-1111-111111111111/virtio-win_servers_amd64.vfd

The files were uploaded to the ISO domain using:

engine-iso-uploader --iso-domain=iso_storage upload virtio-win.iso virtio-win_servers_amd64.vfd
