Hi nvmetcli developers.

Following the NVMe specs I understand that it should be possible to use 
host name or fully qualified domain name instead of an IP address in the 
traddr field.
Setting the host name works, but when I try to attach a device this fails. 
Just changing the host name to a valid IP address and then attaching a 
device works (see below).

May I  miss something or is this a bug?

Not a bug and you're not missing anything.  The kernel doesn't do
DNS lookups, so it need an ip address.  The only enhancement we could
do is to do the DNS lookup in the nvmetcli code, and then store the
resolved IP address in configfs for the kernel.
