Re: Vivado License Manager does not recognize CentOS 7 wireless MAC hostid

The workaround for this problem is to disable consistent network device naming by adding 'net.ifnames=0' to the kernel command line.

Re: Vivado License Manager does not recognize CentOS 7 wireless MAC hostid

Sorry for the delay in my reply, and many thanks for your response.  I'm working on my CentOS 7 system only on weekends.  I did make the change you suggested. 

 

cat /etc/default/grub
GRUB_TIMEOUT=5
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=centos00/swap rd.lvm.lv=centos00/root rhgb quiet net.ifnames=0 biosdevname=0"
GRUB_DISABLE_RECOVERY="true"

 

From what I can tell the only thing this change seems to have done is rename my Ethernet nic to wlan0.  Unfortunately, the Vivado License Manager still does not recognize my MAC address.  Here are the outputs of various commands which hopefully is enough to identify the issue.

 

ifconfig

Re: Vivado License Manager does not recognize CentOS 7 wireless MAC hostid

Hi mlegako@gmail.com

 

Rename your NIC card to ethX to recognized by the Vivado License Manager tool.

 

Thanks,

Vinay

Re: Vivado License Manager does not recognize CentOS 7 wireless MAC hostid

virbr0 is a virtual network device provided by libvirt and can't get renamed. I guess you are not inside the virtual enviroment. But do you have any other (wired) network adapter beside wlan0?
