== VPP_VAGRANT_NICS disappear after "vagrant halt" or "vagrant reload" ==
+
[[VPP/Troubleshooting/BuildIssues | Build issues]]
 
+
More than likely if you've added a NIC via the above env variable, its ended up an orphan after a "vagrant reload".
+
 
+
(many thanks for Damjan Marion for his help)
+
 
+
Sympton:
+
* "ip -o a" doesn't show any "ethx" type interfaces other than "eth0" mgmt
+
* on VPP startup (assuming emacs gud-gdb) you see:
+
  EAL: PCI device 0000:00:03.0 on NUMA socket -1
+
  EAL:  probe driver: 8086:100e rte_em_pmd
+
  EAL:  Device is blacklisted, not initializing
+
  EAL: PCI device 0000:00:08.0 on NUMA socket -1
+
  EAL:  probe driver: 8086:100e rte_em_pmd
+
  EAL:  Not managed by a supported kernel driver, skipped
+
 
+
Fix:
+
 
+
* Don't Panic - there is no need to "reboot" or "vagrant reload --provision"
+
* Do following:
+
  sudo su
+
