Re: [libvirt] [PATCH 3/3] util: Report error if vhost-scsi device file cannot be found

https://bugzilla.redhat.com/show_bug.cgi?id=1523564 If the vhost-scsi device file cannot be found, the generic error "error: An error occurred, but the cause is unknown" is returned. Let's add a real error message to make it clear why the failure occurred. Signed-off-by: John Ferlan <jferlan(a)redhat.com&gt;
