EXOS-VM doesn't boot after adding more NICs


Userlevel 1
Thanks Stephane. So I created the vm from the iso image and powered it on and it booted successfully. I then followed the install guide to add more nics, but now when I power on the vm it does not boot. I keep getting a watchdog warning message that has seconds that count up each time the error message appears. Note: This conversation was created from a reply on: How to enable MPLS on ExOS VM ?.

Hi Darren,
A few questions...
  1. What platform are you running your VM on?
  2. How many NICs did you add?
  3. What's the exact error message?

Drew,
I did some more troubleshooting and i figured out what was causing the watchdog error. Adapters 3 and 4 were causing the issue. i created a new VM and disabled each adapter at a time starting with 4, and then i started the VM after disabling the individual adapters. The error went away when the VM booted after adapters 3 and 4 were both disabled. I then added 6 nics/ports and the VM booted without a problem. i hope this helps you narrow down the issue with the VM.

That would be worth to check with another hypervisor, the problem may come from VB. I'm not sure we did any change to the software dataplane recently.

I just launched a VM running EXOS 16.1.3.6 with VB 5.0.14r105127. That VM has the usual 4 adapters Up plus one more added manually. No issue.

Ok. Maybe I have to download the iso again. Thanks

yes. i downloaded the iso again and got it to boot up. but i still see the same watchdog error. ill put in some configurations on the switch and it appears. i then have to start my configurations again. i dont save the configs after each change i make because the save process takes a long time.

Darren,

Can you please execute the following command?
vboxmanage showvminfo [/code]If you are running virtualbox in a windows environment you will have to move to the installation directory of virtualbox (usually C:\Program Files\Oracle\VirtualBox)

I'm interested in the part that shows the nic configuration. Something like this:
