Licensing - Vivado License Manager (VLM) shows my machine HostID as "000000000000"

Description

Vivado License Manager (VLM) shows my machine HostID as "000000000000"

The floating license utilities available with Vivado 2014.1 and earlier will not start on my machine (hostID does not match).

Lmutils returns a host ID of "000000000000"

[<User>@<address> ~]$ lmutil lmhostid

The FLEXnet host ID of this machine is "000000000000"

Solution

This issue occurs because the Ethernet port name for the machine is using a new format that is not recognized by the FlexLM tools.

Typical port names used on many new Linux machines are em0, em1, em2, etc ... instead of the traditional names, eth0, eth1, eth2, etc ...

Vivado 2014.1 uses Flex licensing version 11.11. Flex version 11.11.1 is required in order to read emX format port names.

The attached zip file contains license utilities (including xilinxd and lmgrd) which can be used to serve a license on a machine with IP address port names using the emX format.

An alternate solution would be to change the port names.

In the following example, the Ethernet Adapter is renamed to eth0:

    1. cd /etc/default
    2. sudo vi grub
    3. Add this to the end of GRUB_CMDLINE_LINUX: "net.ifnames=0 biosdevname=0"
    4. <esc>:wq
    5. grub2-mkconfig -o /boot/grub2/grub.cfg
    6. cd /etc/sysconfig/network-scripts
    7. sudo mv ifcfg-enp0s3 ifcfg-eth0
    8. sudo vi ifcfg-eth0
    9. Change NAME="enp0s3" to NAME="eth0"
    10. <esc>:wq
    11. reboot
